Don't take the bait!
So, I published a post yesterday: Trackback Spam Be Gone: What I Use To Cut Down On Junk Trackbacks.
As the comments started to pour in, I realized that I had a bit more explaining to do on the topic.
Some of you might know what trackbacks and pingbacks are, some of you might THINK you know, but all of you might wonder why is this so important for me to write a whole post about.
And I will get to that… later.
For now, let me quickly tell you what trackbacks and pingbacks are.
Essentially, they both are ways for blogs to communicate with each other.
Because of the kind of technology trackbacks use, they are much more prone to spam than pingbacks.
What Are Trackbacks And Pingbacks?
Let me show you an example of a legitimate pingback.
1. This is what it looks like in my pending comments (click to enlarge).
2. When I click on it, it goes to Tia’s BizChicksBlog post, where I see that she linked to one of my posts via a hyperlink.

3. This is what the pingback looks like after I approve it - it will show up in the comment section all the way at the bottom.
Now here’s the important part of using pingbacks: you don’t have to do a thing to use them.
WordPress does all the work for you (assuming you are on WordPress platform, of course).
If you link to other WordPress sites in any blog post, they’ll be notified automatically using pingbacks, no other action necessary.
Your blog will tell their blog that you hyperlinked to their post. Their blog in turn will come back to your blog - automatically of course - and VERIFY that such a hyperlink indeed exists.
That verification process is what makes pingbacks a much better option over trackbacks and that’s what WordPress automatically uses.
Now, let’s take a look at the other side of the coin: spam trackbacks.
1. This is what they look like in my pending comments (click to enlarge).
2. This is what one of those sites looks like when I click on the trackback link (their link to my blog is highlighted in yellow - click to enlarge).
This is what is referred to as a spam blog or splog.
What makes a splog a splog?
- they provide no content and no value
- their sole purpose is to earn money via AdSense, etc. or build links for a primary site of sorts
- non-existent traffic, comments, or any other evidence of user engagement - after all, that’s not what they are for.
3. If I were to approve this spammy trackback, I would end up with this kind of link as part of my comment section:

You can see right away that it doesn’t make much sense, unlike the previous example with the legitimate pingback.
What’s the point?
So far I’ve given you a bunch of education on pingbacks and trackbacks. It might or might not make much sense to you and I understand that. To be quite honest, I am not completely in the clear on the issue myself.
And that’s OK.
As a blogger, the ONLY THING you need to learn out of this is what a splog is, what it looks like, and the fact that you should NEVER-EVER approve such trackbacks.
What’s the Big Problem with Spam Trackbacks?
Once approved, trackbacks and pingbacks provide links FROM your blog TO their blog.
Whether you know much about link building or not, you need to know at least this: you will never be penalized for the kind of links that are coming to your site (you just won’t rank well), but you MIGHT be penalized by Google for the outgoing links from your site, since they are completely under your control.
If you are hungry for comments as social proof, you might be tempted to approve a spam trackback or two or even a whole bunch of them just to get rid of the dead silence on your blog - “Hey, look at that, somebody actually links to me - they must really like me!”
Really bad idea.
So learn what splogs look like and stay away from them altogether.
Learn more about link building:
How To Use Trackbacks for Traffic Generation
Now on to the fun part.
There are ways you can use legitimate trackbacks to your advantage (notice, I use the words “trackback” and “pingback” interchangeably here - because as long as they are legit, who cares what they are called!)
Notice how I linked to Tia’s blog above?
When she sees my trackback in her pending comments queue, she will most likely come back to this post and maybe even leave me a comment (won’t you, Tia?
).
Once she approves the trackback, her readers will see it as well and might come back and check out my blog.
So….
TRACKBACKS = TRAFFIC
Now imagine you write a post with 5 trackbacks to 5 different blogs? Or 10? You see my point.
This is a great way to spark an interest among bloggers who might otherwise never have a reason to come to your blog.
Learn about more ways to generate traffic:
Trackback Traffic Generation Tip You Must Use
I noticed that many bloggers use trackbacks incorrectly.
Many of you mention other blogs and bloggers on your sites, but when you link to them, you link to THEIR HOME PAGE.
BIG mistake!
Home page doesn’t have comments, so those trackbacks have no way of showing up in their comment queue. That basically means they will most likely never know you linked to them.
Solution: ALWAYS link to a post. Any post.

Hi Ana I have a question that maybe I missed in one of the post above. I use some article marketing to build links I know it is not as good as it once was but I do see some pages rank well. I receive alot of trackbacks from these sites. Should I approve them or just delete them. Most of them go back to my article but I don’t see any real value in having them on my blog in the comment section. What is your opinion
Definitely don’t approve them, Lester.
Thanks for the reply I didn’t think I should approve them just wasn’t sure thanks for the help
Hi Ana, This post is a life saver for me since I was just thinking about trackbacks and pingbacks yesterday. I know now what to accept and what to get rid of on my blog. It’s really cool to know what to look for to get rid of what you reffered to as splog. The way you explained it is clear and since I know you to be the go to gal for this kind of information, I will definitely put it to use A.S.A.P.
I appreciate how you put this together…simple and to the point.
Thank you so much Ana
Stephane
You are very welcome, Stephane; glad I could help.
Hi Ana,
Is it useful to approve pingbacks that come through from your own blog. E.g. a pingback from a link from one of your own pages to another of your own pages bcz you provided a link in your own article? Does that make sense? Or am I just better to delete the “internal” pingbacks?
Thanks, Eileen.
The only reason to approve your own pingbacks is for internal linking purposes, Eileen.
However, if you are using a related posts plugin of sort or link to relevant posts within your content, then you don’t need them.
I never publish them personally.
Thanks for that golden nugget you provided at the end of your post, much appreciated!
You are very welcome, Tyronne.
Hey Ana,
thanks for publishing this. I reckon I was about 80% of the way there with understanding trackbacks and pingbacks - as it happens I was doing the right thing as I always check out where they come from and if the site looks dodgy I don’t approve & trash it.
Now I think I get it almost completely - and I’m off to read your related posts on the subject to make sure!
Thanks again Ana,
Alan
You are welcome, Alan - thanks for coming by!
Hi Ana!
This post was the most valuable one I have read in regards to Wordpress, as I am a wordpress ‘newbie’ blogger. So to speak. I did not know what trackback or pingbacks were and how they can be both damaging and valuable. Very glad i have subscribed to your email and site.
Have a great day!
crystal
Thanks for such enthusiastic thumbs up, Crystal!
This is definitely great to know early on. I didn’t know this when I started and now paying for it!
Great advice to link to posts and not to homepage, I should begin to use pingbacks too. As for me on my blog I use Lyvefire so there is pratically no spam but I’ll surely go to check any old tracback I received before using it. Anyway my way to deal with them was to check the link and if it was a splog throw it into the spam bin. Which happened 95 % of times.
Let me ask a question pretty unrelated, have you ever written a review about SiteBuildIt? Honestly I’ll stick with WP and won’t change but I know a lot of people talk about it and I’d like to know, just for curiosity, if there is something else beside a good affiliate plan with it. Who better than you can write a honest review? And if you’ve already done it forget the question, I haven’t read all your articles.
Thanks again for another great article.
I’ve never personally used it, Andrea, but I did have a client who wanted to improve his design and SEO and we ended up moving him to Thesis theme on WP.
I’ll stick with WP. lol
I see Ana, but given that SBI is pushed a lot, for its affiliate program probably, in many places a honest review would keep things in balance. At least before buying it customers would have a chance to hear another version. Unbiased as you don’t earn a penny saying that WP is better and why.
Anyway I understand what you mean.
Have a great weekend!
Love the idea, but that would require me to build an SBI site, and that takes quite a bit of work. lol
Yea, trackback spam is annoying as captchas dont block them. So you have to manually check the link(s), and report accordingly. Annoying at best.
Brad invites you to read: Google updates Chrome stable to make it safer/faster
Annoying it is, Brad.
Thank you so much for this super post, Ana. I’ve already linked to it from my post about the dirty, rotten trackback spammers who are KILLING trackbacks. Their selfishness has ruined an effective tool for raising awareness as I explain in my post about trackback spam tools to avoid.
Many legitimate bloggers are falling for these plugins that are being heavily promoted on places like Warrior Forum. They need to know they are ruining their reputation and will be blacklisted by many influential bloggers.
Some of my favorite most popular blogs have already blocked all trackbacks because they (and GrowMap) are being simply flooded with spammy phony trackbacks. While link building IS necessary, doing it by spamming blogs is NOT the way to do it!
I just wish pingbacks consistently worked. They don’t. The wisest bloggers who are blocking trackbacks are using alerts and setting up searches to let them know when other bloggers link to them so they can support their efforts and share the posts that include references or links to them.
Maybe we should even tell each other to make sure? We could leave a comment in a post, or send a tweet or I could add a section for that to the new forum @VernessaTaylor and I are setting up for DoFollow CommentLuv bloggers. I encourage all of your readers who are DF CL bloggers to leave a comment in my blog so I can get them on my lists.
Gail Gardner invites you to read: Guest Posting: Guest Blogging Tips ~ My Guest Posts
You are so right, Gail - it’s a catch 22 in many ways.
We are tired of the spam trackbacks, but because we block them every way we can, we also end up blocking the legitimate ones.
I started sending email/tweets to the people I mention in my posts. Lots of extra work, but it’s the only way that works for now.
Thanks for coming by and the link!
Hmmm. From now on I’ll try to always link to a specific post on your blog, Ana!
Also Ana, there are a LOT of spammers on G+ - men and “women” from India - all marketing BS. I now delete all emails from G+ without even bothering to look at who is linking or circling me or whatever it is they do…
I’m also compiling a list of bot blogs, so should anybody find one - find me and leave the link here:
http://dave-lucas.blogspot.com/2012/02/blog-or-bot.html
Dave Lucas invites you to read: #Wordless Wednesday
I choose not to be notified about anything from G+ - it can definitely get too overwhelming too quickly.
Thanks for the link and I’ll let you know if I see any bots crawling around.
Hi Ana,
I was one of the ones mentioned at the beginning of this post that “thought I knew all about trackbacks”. I had read several explanations regarding it and it seemed okay to accept. I also heard about Digi Links and had no idea it was a spammer plugin. I bought the CommentLuv plugin from you some time ago, but haven’t got it installed on all of my sites..been awful busy and a bit lazy too I’m afraid. Thanks again for very useful information and helping to avoid penalties for bad linking.
Glad I could shed some light on the issue, Gustav.
Now onto more serious matters: I do appreciate your purchase, but now I have to give you a virtual kick in the you-know-where.
You haven’t take advantage of CL Premium yet???
DO IT!
Hi Ana, I believe in one word, LinkBacks (Trackbacks and Pingbacks ) allow you to notify another site that you wrote something related to what is written on a specific page…. but it is unfortunate how human beings can take good ideas and abuse it.
It seems like spammers are always one step ahead of us, Sharon.
Thanks for writing this about trackbacks and pingbacks, Ana. Before reading this post, I was mostly ignorant about trackbacks and pingbacks. Now I have a much better idea about how they work. Once again, thanks.

I was confused until I researched the topic, Kathy - most of these things are not intuitive at all!
evening Ana,
I’m so sick of spam on my site that I’ve turned comments, pingbacks etc off. Tonight while posting an article that I’d written and was recently published, I debated about turning ping/trackbacks on because the content of the article is important to a non profit org that needs some notice right now. In my mini debate I did a search on the topic and found your post. This is a great help! Thanks for taking the time to illustrate the ping/track thing.
all the best to you,
Cindy O’Neil
Cindy O’Neil invites you to read: Song Proceeds to ‘Give Them Wings’
Glad I could help, Cindy.
I’d highly recommend you install a free anti-spam plugin called GASP - it’s great at controlling both spam bots and trackbacks.
wow, you’re fast. at some point i certainly will check out your recommendation. to be honest, i’m putting every bit of energy i have into a donation event for the World Parrot Refuge. there’s just so much to learn and figure out with technology evolving at warp speed. wouldn’t it be great if compassion developed that fast too
all the best to you Ana.
Cindy
Cindy O’Neil invites you to read: Song Proceeds to ‘Give Them Wings’
Thanks, Cindy - you too.
Ana, this article is so informative. I became intrigued by all the trackbacks that were being “moderated” by G.A.S.P., the plugin that also blocks robospam comments. Was GASP being too conservative and blocking good trackbacks? I checked out a couple. They were splogs! I didn’t know the name before I read your article, but even then I could see that they were bogus. So I don’t question GASP any more. It’s protecting my blog. BTW GASP comes “bundled” with the CommentLuv Premium plugin.
Yes, Astro, I have CL Premium on this blog and love GASP.
Thanks Ana. Yours is the first clear explanation of Pingbacks I have come across after searching for more than an hour.
Glad to hear the buck stopped here, George! LOL
Thanks for making this distinction, Ana. I’m still a little confused why sometimes I get the pingback from other WordPress blogs and sometimes I do not.
In the past week, I had 5 links included in posts on WordPress blogs but haven’t received a pingback from them. I would not even know about these posts had it not been for Twitter. What gives? I would gladly approve these pingbacks.
I’ve had the same issues when I link to my other blogs. Sometimes these pingbacks appear, and sometimes they do not. It makes me wonder how many times I’m linking out to someone and they don’t know about it.
Any suggestions?
Nice article, I was always confused about the difference between pingbacks and trackbacks
Enjoying your posts Ana. Nice to see you talk about both inbound and outbound links, which form a site’s overall link neighborhood. Most people miss this. Quality over quantity always required - on both sides. Keep up the great work!

In WordPress.org, is there a way to auto approve ping backs? I get at least 15 a day and it adds junk to my email box.
Deepak invites you to read: Calling all American Manufacturing Facilities!
Hi, Deepak:
Do you autoapprove comments on your blog?
If so, it should take care of pingbacks as well. If not, then I don’t think there is a way to do it.
By the way, pingbacks can still be spammy.
I get on average about 10 spam pingbacks on my blog, so I wouldn’t recommend autoapproving them for that simple reason.
Ana
Ana,
Thanks for your advice. Later on last night, I went to my gmail account and marked certain criteria to make the pingbacks already read messages. Now I can just approve or dissapprove all at one time every few days - efficiency!
Deepak

Brilliant solution, Deepak; thanks for sharing.
Ana
Ana, thanks for explaining what trackbacks and pings mean. There are a lot of people out there that don’t understand this.
As for linking to a individual post instead of a post, never thought of doing it for trackbacks. I normally do it because an article is worth mentioned or is part of my article. In the future, I will keep this in mind when mentioning a website. I will try and search their site for a related topic and see how well it works.

If you are linking to someone’s blog, might as well get a link back and possibly even some traffic, huh?
Good for them and good for you.
Plus, I hate finding out that someone wrote an article about me and I had no clue simply they linked to my home page.
Ana
Hi Ana.
This is the best explanation of trackbacks vs pingbacks that I have come across. I was not totally clear on the two in functionality before, but fully understand now thanks to you.
I will rummage through my archives and seek out any undesirables.
Good stuff!

Hi Ana, thanks for the articles. I was not in clear about these two earlier until I did my own research like you did in your article. After I found out about the trackback (since I got a lot of those and deep down, I know there are spams), nowadays I mostly approved pingback.
I wrote about the difference in one of my blog post but in my local language. Since I found your article, I will link back to your post here for an English version. Thanks a lot.

Rob invites you to read: 2 Print Design Samples For Various Use
You are exactly right, Rob - it doesn’t seem like the kind of thing that should take a priority.
However, now that I’ve done all the research, there should be no excuses to not know the ill effects that can have on your blog.
Have a great Sunday.
Hi Anna. I now know what a splog is. I was getting trackbacks in my comments and when I followed it I had an entire poem I had written on one of these sites. I commented to get it removed and it was never approved so I went to their web host and complained. They do come in very handy to find out who’s scraping your content.
Hi Karen,
I can imagine how frustrating that incident was and how you need to waste your time just to get rid of it and solve the problem. At least now you can be more careful with it.
Carry on,
Ana
You’re right. Wordpress makes the pingback procedure effortless since it is completed automated. I didn’t really have a clue to what trackbacks were but I have seen them numerous times around the web. T
hank you for the in-depth information on what trackbacks really are and how to use them properly. I have never used them before, but see how effective they could be.
You are welcome, John.
I thought it was important for my readers to know how to link to good site and stay away from spam; glad you agreed.
Ana
Wow, you did it again, Ana!
I’ll have to go through my blog and see what splog I’ve approved unknowingly. Thanks for the tip (and for adding ONE MORE thing to my to-do list!) LOL
Also thanks for all the visuals. They really helped me to understand!
Thanks!

Just make sure you stay away from spam - the entire point of the post.
Ana
At one point, I was getting consistent spam from 1 specific IP adddress. I was so fed up I contacted my hosting company, Midphase, and told them directly to block & put up a firewall from that IP. It was some Russian based server & Russian base site with the same spammy links.
I actually just installed the Growmap plugin myself. But I still do use Akismet as well.
The one thing I wonder however, is choosing between a good and the right, or most efficient commenting system. I see a lot of bloggers using Disqus, but there are also IntenseDebate. I think Auttomatic needs to start taking commenting on their system more seriously though.
Darrin Kuykendall - Converting Non-Believers invites you to read: Mission Review- Business Process Systemizing
You know, Darrin - I do get a lot of spam links from certain IP addresses; one of these days, I’ll get mad enough to call my hosting company!
One thing about Disqus - it’s a nofollow comment system, and I have a dofollow blog. So that doesn’t work too well. I am not sure about Intense Debate.
Also, if you use the defaul tWP comment system, your comments can actually rank on Google as any other page on your blog would; not any other comment system though.
Ana
Yeah, that’s a great point about Disqus being no-follow. I didn’t even think about that.
One feature I do kinda miss is from Seesmic — when they had the ability to video comments. I’m not sure if the plugin is still around anymore or has been updated to the latest versions. Video commenting may have not picked up that much in the past, but, the way things are moving towards more active engagement & focus on getting quality comments, it might be a something bigger int he future.
Darrin Kuykendall - Converting Non-Believers invites you to read: Mission Review- Business Process Systemizing
Wow, video comments - the first one for me, quite honestly.
Would be interesting to see if they come back!
Hi Ana,
Great to have had the semantics sorted here. To be honest I have always discerned these by those that are useful which I like and those that have nothing at all to do with value for my blog. I have a tad more insight now after your explanation. Thank you.

It’s the other type I want readers to be aware of.
Good to see you!
Thanks for the information Ana - but I am not much wiser - I see pingbacks etc on my blogs - but don’t know how to do them - e.g. say to this blog of yours - bit thick I know! LOL
cheers
Pete
Hi Pete,
I’m sure by now you already have an idea how to recognize pingbacks and trackbacks.
Carry on,
Ana
I would recommend linking to a post on their blog that has some relevance, at least, to the post your are linking from. And if I have to leave a good impression, I would make sure the link is never nofollowed.
Good suggestion, Pulkit.
In cases, I can’t find/don’t have time to find a relevant post, I simply trackback to the latest post.
Anything is better that the home page.
Ana
Thanks Ana for an easy to understand explanation of this topic. I am learning so much by visiting experienced bloggers sites like yours. So far are all my trackbacks have been genuine but now I will know if any are not. Thanks so much for sharing this Ana. Much appreciated.

This is an exceptional explanation. Thank you for making it so easy to read and idiot proof
- and for including so many examples. Like you said, sometimes we think we know what they are. It seems I had a lot more to learn on the topic.
I have a Question for you if you don’t mind.
How do you get your pingbacks to look all nice and neat like that? I mean with just the title and without all the added html and so forth. Mine don’t look very pretty
. Do I need to install something or just tweak the settings somewhere?
Thanks again for this very efficient and helpful tutorial.

Ingrid Abboud invites you to read: 17 Things About Me- If You’re Curious to Know – My Special Bday Post!
I took a look at your trackbacks, Ingrid, and my educated guess is it’s because you are using Disqus comment system.
I used to use it on my blog as well, but dropped it after a while; mostly because it’s a nofollow system and I wanted to keep my blog dofollow, but also because of the looks.
Love seeing you here; are you kidding me?
Ana
Ana,
Thanks so much for taking the time to check that out for me. I absolutely want to be a DoFollow blog. I’m embarrassed to say that I actually thought it already was
!
As for Disqus - although I switched to it from IntenseDebate several months ago and I seemed to like it - I think I will be switching again very soon (I mean now) to CommentLuv. I think readers can also benefit from this much more and I love the engaging community.
I think Patricia from Lavenderuses will also be happy to hear that lol
.
Now all I need to do is not screw up and lose all my comments in the transfer process! Cause I lost a couple here and there when switching the second time.
PS - Love the fact that you love seeing me here
. Cause you know I’ll be back!
