Spam Links on WordPress site can affect your Website SEO and Google adwords (This may lead to Google adwords suspension or Google ads disapproved due to malware). As a WordPress website owner, spam injection is one of the dreaded and well-disguised hacks you should be aware of. If you have been a victim of a spam link injection , it can be an extremely exasperating experience to find and fix the hack. Black Hat Hackers infect WordPress sites, by injecting spam links directly into the database.

Also know more about – What is SEO Spam & How to Remove it
Spam URL Injection can be defined as a malicious activity initiated by hackers to gain access to your WP website. This particular theme is termed as spamdexing or SEO spam.
Instead of making the best possible efforts to rank the pages legitimately on search engine ranking pages (SERPs), the hackers will use the top-ranking pages of your website to take away your years of accomplishments.
Let us discuss the things they include –
- They will insert particular keywords that we deem as spam in all those pages that are well-ranked on SERPs (search engine result pages).
- The hacker will insert hyperlinks on your website’s pages. All your users on wordpress site redirects to another spam website whenever they click on these hyperlinks.
- They will also send spam emails to your customer database.
- At times, they create new pages as well.
- These hackers also display ads and banners of their products on your website.
Using SEO spam injections, the hackers can hide the website from its owners for as long as they can, this is what makes this malicious activity dodgy.
So, before we move any further, you have to ensure that you are a victim of SEO spam, after which we can move ahead and learn how to fix it.
Link Injection Hack bots look for known exploits (WordPress SQL Injection, incorrect WordPress folder permissions, etc) This allows them to insert spam files/links into your WordPress Themes, plugins, and core files.
Let us understand the Spam Link Injection with the help of an example –
<div style=\"\\64\\69\\73\\70\\6c\\61\\79:\\6e\\6f\\6e\\65\"> <a href=\"http://www.fcit.usf.edu/li/viagra.html\">viagra</a>\r\n<a href=\"http://www.fcit.usf.edu/li/free-viagra.html\">free viagra</a>\r\n ... lots more ... </div>
The moment that “style” attribute (inline CSS) was rendered in a browser, it converted into display: none and therefore were not visible.
The hackers decided to use this method because they think that the owner of the blog may not be aware of the fact that the links were inserted since they are not visible. Google does not provide link credit to the links that are within a container having display: none. However, the hacker believes that Google bot will not be able to identify that this div is hidden because of the unnatural code.
How spam Links can affect your site’s SEO?
If you engage in low-quality link building, your website is more likely to be penalized by Google. Your website will also face punitive action and as a result, the rankings will also plunge down. Here you can look at how Google penalizes the link manipulators.
This is the case where Google will apply a penalty manually after going through your profile. The review is triggered due to the following reasons –
- ü Your standing as a competitor in your niche.
- ü Spam accusation by a competitor.
- ü Activation of algorithmic search because of the presence of spam links on the website.
Google may send you following message in your search console –
Algorithmic Link Spam Penalty
To abate the link manipulators, Google has rolled out Penguin and also to reward high-quality websites. Through the years with the updates, Penguin can catch spam links and penalize the websites. In case, of late, you have received an algorithmic penalty, you will not get any notification, but rather you will witness a significant fall in the organic traffic, something like this –
Signs That Your Site Is Hacked With Spam Links
If you are skeptical of being hacked or just want to be sure, consider the following ways in which you can be sure you have been hacked.
If you have malware on your website that can prove detrimental for the users, then Google will blacklist you. Such hacks go unnoticed for a long time usually, this gets detected by Google before you, as the owner of the website, do.
Since Google has found malware on your website, you will receive an email carrying a message that your website has been blacklisted. Your users, trying to access your website, will be shown a notification or warning message like this –
Your website may also carry a warning on the SERPs – “This site may be Hacked” warning message.
These actions are initiated by Google as user experience is its first concern. They aim to provide the users with quick, safe and relevant results. Therefore they ensure that, no matter what happens, the security of the users is not jeopardized.
Web host suspension
Pretty much like Google, your wordpress site can be suspended by your web host as well. Your web host will notify you that your web hosting has been suspended. They will either claim that you have malware on your website or ask you to get in touch with them to know the reason behind the suspension of the account.
There is a reason why these web host providers suspend hacked accounts. Each website is provided with a certain amount of resources. In case your website is hacked, chances are that it will surpass these allotted resources. Besides, if you have a shared server, you will put other websites, on the same server, at risk.
