One of the oldest and easiest ways to rank on Google was to just hit blogs that are related to your niche. You just put up a link in the form of your name, you use your keyword as your name and link it to the target webpage. This was very effective if the blog that you are commenting on is a do-follow blog. Meaning the link on your comment profile will actually be followed by Google bot. As you can well imagine, spammers, the world over, got on the same bandwagon and just mercilessly blasted comments all over the planet in a bid to get links. Why would they do this? One of the ways Google ranks a webpage is to count how many backlinks linked to that page from many different websites. It also factors in the quality of those websites and other considerations. Thanks to Google Penguin 2.1, these easy tactics no longer work. This is why if you have been receiving take down notices from people that have commented on your website or sent in guest posts you would understand how widespread this problem is. A lot of reputable websites intentionally leave comments on in the hopes that the spammers and scammers who put up those links would get penalized by Google.
The SEO game has changed dramatically. Well, everybody knew that it was changing with Panda. As bad as panda was, because of its penalties based on content, things really got bad with Penguin. Penguin now factors in the links that go to your website. It didn’t used to be this way. Now, technically speaking, if a competitor wanted to sink your rankings all that competitor needed to do is to create tons of spam links and point it to your website. Another key development is Penguin 2.1, which tracks the quality of the websites linking to you. So a lot of blog comments and blog comment spam are basically counting against your website if you place those comments at the wrong sites.
So, where fo you go from here? According too many SEO experts, the focus should be on getting people to link to your content naturally. Of course, this is too slow or too timid for many SEO’s. As a result, these SEo specialists would send email to many websites that discusss certain issues on blog post and give them links as suggestions regarding what they wrote. For example, if somebody wrote about black lung disease or lung cancer, an SEO would send an email to that blog and say, “well, that’s a very interesting article but did you consider the fact that there is this new medical study that disputes what you said” and there is a link included. Of course, this is all in a bid for the recipient to publish that link. This is an interesting twist on the old blog comment spam approach.
Personally, I think this is a step to the right direction because at the very least it pushes SEO’s to work a little bit harder in providing a better match between what they want the recipient to link to and the content on the recipient’s website. Of course, this method is going to be abused since people are lazy. They don’t bother to read the actual post that is on the recipients website. Be that as it may, it does show a step in the right direction in terms of a better quality.
