If you are using WordPress, you should know about wordpress spam injection. Otherwise, your blog may be hit and yet, you are not aware of them.

So, whose blogs are most likely to get hit?

1) Blog with high pagerank
2) Blog with good keywords
3) Blog with good traffic

How do we know?

We won’t know because it is not easy for us regular users to trace it. You cannot see the spam links inserted by viewing source codes. For us who are not experts, we won’t even know where to start searching. I read a few posts and still do not understand the workaround it.

What are the signs?

1) You are suddenly getting PSA ads on the main page.
2) Your traffic dropped
3) And if left unattended, you will lose your pagerank and get some good keywords de-indexed

Who are behind these?

Blackhat SEO who uses dirty tactics to inject their spammy links into your blog without your knowledge.

I saw PSA ads on my personal blog and wrote to Google Adsense. Here’s the reply I received :

Thanks for your email. I understand you are concerned about the fact that
public service ads are appearing on your site. Our specialists
investigated and found that pornographic links and links related to
prescription drug offers have been injected into the bottom of your pages.
These links are only visible to web crawlers so you may not see them if
you view the source of your pages. Because our system does not return ads
to pages detected to have adult content, relevant paid ads will not appear
until the links are removed. These links may have been placed on your site
without your knowledge in an attempt to boost other sites’ search engine
rank.

We’d recommend that you contact your webmaster to fix any site
vulnerabilities which may have allowed the links to be placed on your
site. For more information about security for webmasters, see

You may also with to perform a search for results related to “wordpress
spam injection” for more information about the issue.

Once the links have been successfully removed, paid ads or more relevant
ads should start appearing again within a week.

Cheers,

How to prevent it?

Hopefully, you have someone who is an expert who can trace where they had inserted the codes. Remember that these people who inserted the codes are really expert and they can breach WordPress security to get into our folders.

Also, let’s hope WordPress patch up this real fast. I have a list of some useful sites which I have bookmarked. But let me solve my problems on wordpress spam injection first and see which links’ recommendation works.
