It has probably happened to you: you're reading articles or watching videos on the web, and you come across some unrelated, gibberish comments. You may wonder what this is all about. Some webmasters abuse other sites by exploiting their comment fields, posting tons of links that point back to the poster's site in an attempt to boost their site's ranking. Others might tweak this approach a bit by posting a generic comment (like "Nice site!") with a commercial user name linking to their site.

Why is it bad?

FACT: Abusing comment fields of innocent sites is a bad and risky way of getting links to your site. If you choose to do so, you are tarnishing other people's hard work and lowering the quality of the web, transforming a potentially good resource of additional information into a list of nonsense keywords.

FACT: Comment spammers are often trying to improve their site's organic search ranking by creating dubious inbound links to their site. Google has an understanding of the link graph of the web, and has algorithmic ways of discovering those alterations and tackling them. At best, a link spammer might spend hours doing spammy linkdrops which would count for little or nothing because Google is pretty good at devaluing these types of links. Think of all the more productive things one could do with that time and energy that would provide much more value for one's site in the long run.


Promote your site without comment spam

If you want to improve your site's visibility in the search results, spamming comments is definitely not the way to go. Instead, think about whether your site offers what people are looking for, such as useful information and tools.

FACT: Having original and useful content and making your site search engine friendly is the best strategy for better ranking. With an appealing site, you'll be recognized by the web community as a reliable source and links to your site will build naturally.

Moreover, Google provides a list of advice in order to improve the crawlability and indexability of your site. Check out our Search Engine Optimization Starter Guide.

What can I do to avoid spam on my site?

Comments can be a really good source of information and an efficient way of engaging a site's users in discussions. This valuable content should not be replaced by gibberish nonsense keywords and links. For this reason there are many ways of securing your application and disincentivizing spammers.

• Disallow anonymous posting.
• Use CAPTCHAs and other methods to prevent automated comment spamming.
• Turn on comment moderation.
• Use the "nofollow" attribute for links in the comment field.
• Disallow hyperlinks in comments.
• Block comment pages using robots.txt or meta tags.

For detailed information about these topics, check out our Help Center document on comment spam.

My site is full of comment spam, what should I do?

It's never too late! Don't let spammers ruin the experience for others. Adopt security measures discussed above to stop the spam activity, then invest some time to clean up the spammy comments and ban the spammers from your site. Depending on you site's system, you may be able to save time by banning spammers and removing their comments all at once, rather than one by one.

If I spammed comment fields of third party sites, what should I do?

If you used this approach in the past and you want to solve this issue, you should have a look at your incoming links in Webmaster Tools. To do so, go to the Your site on the web section and click on Links to your site. If you see suspicious links coming from blogs or other platforms allowing comments, you should check these URLs. If you see a spammy link you created, try to delete it, else contact the webmaster to ask to remove the link. Once you've cleared the spammy inbound links you made, you can file a reconsideration request.

salam every one, this is a topic from google web master centrale blog: Co-written with Ryan Moulton and Kendra Carattini

We wanted to give a quick update about "Googlebombs." By improving our analysis of the link structure of the web, Google has begun minimizing the impact of many Googlebombs. Now we will typically return commentary, discussions, and articles about the Googlebombs instead. The actual scale of this change is pretty small (there are under a hundred well-known Googlebombs), but if you'd like to get more details about this topic, read on.

First off, let's back up and give some background. Unless you read all about search engines all day, you might wonder "What is a Googlebomb?" Technically, a "Googlebomb" (sometimes called a "linkbomb" since they're not specific to Google) refers to a prank where people attempt to cause someone else's site to rank for an obscure or meaningless query. Googlebombs very rarely happen for common queries, because the lack of any relevant results for that phrase is part of why a Googlebomb can work. One of the earliest Googlebombs was for the phrase "talentless hack," for example.

People have asked about how we feel about Googlebombs, and we have talked about them in the past. Because these pranks are normally for phrases that are well off the beaten path, they haven't been a very high priority for us. But over time, we've seen more people assume that they are Google's opinion, or that Google has hand-coded the results for these Googlebombed queries. That's not true, and it seemed like it was worth trying to correct that misperception. So a few of us who work here got together and came up with an algorithm that minimizes the impact of many Googlebombs.

The next natural question to ask is "Why doesn't Google just edit these search results by hand?" To answer that, you need to know a little bit about how Google works. When we're faced with a bad search result or a relevance problem, our first instinct is to look for an automatic way to solve the problem instead of trying to fix a particular search by hand. Algorithms are great because they scale well: computers can process lots of data very fast, and robust algorithms often work well in many different languages. That's what we did in this case, and the extra effort to find a good algorithm helps detect Googlebombs in many different languages. We wouldn't claim that this change handles every prank that someone has attempted. But if you are aware of other potential Googlebombs, we are happy to hear feedback in our Google Web Search Help Group.

Again, the impact of this new algorithm is very limited in scope and impact, but we hope that the affected queries are more relevant for searchers.this is a topic published in 2013... to get contents for your blog or your forum, just contact me at: devnasser@gmail.com
