I’ve decided to create another case study, this time demonstrating whether or not writing comments on blogs that do not use the NOFOLLOW attribute will help search engine rankings from the links that are received.
To facilitate this, I’ve created a brand new AdSense site based around a niche theme. It has 11 unique articles on it (nothing from free article sites).
I’ve also written a script which did some massive data mining through Google to find about 600 blogs in a variety of subjects that do not use the NOFOLLOW attribute. (In case you don’t know what that is, the NOFOLLOW attribute prevents search engines from counting the link in their rankings.)
I’ve already had about 16 comments posted to these blogs. These are NOT spam comments. These are quality comments related to whatever post the comment is placed on.
It will take a couple of weeks for all 600 comments to be completed. Once they are, I will post an update letting you know how many comments were kept by the blog owners (some blog owners will not approve comments that use keywords as the comment author name for optimization purposes).
I’ve already seen some results from just the 16 comments made so far. Here’s my search engine crawler stats from the day after posting the first set of comments:
Notice that all 3 engines hit the site, and Google crawled the entire site, the next day after posting the comments.
Two days after posting the comments, the home page of the site is appearing in Google’s index.
So far, so good. Google is apparently following and counting the links. I’ll post an update in about two weeks.
=>> The Continue Post below :
I promised an update to my post above where I had 600 comments posted to 600 different blogs for a brand new site. My goal was to see 1) how many of the comments would “stick” (meaning the blog owner would not remove the keyword-targeted link from the comments) and 2) whether or not I would get any search engine value from these blog comments and links.
My gut told me “of course you will”, since Google loves links and this was a pretty easy way to get more inbound links. Get inbound links it did, too. Yahoo! is currently showing 195 links into the test site. That’s roughly 1/3 the number of comments made, but the reality is that many of the links Y! is showing are duplicates. The real number of successful comments with links is about 100.
Unfortunately, because so few of the links “stuck”, the site didn’t make it into Google’s top rankings for the keywords I was hoping for. The site has only received 77 unique visitors in the past 3 weeks, and of those only 4 were from Google (the rest were from the blogs I had comments posted on).
I think the lesson learned here is that you can get quality in-bound links from blogs, and you can do so very inexpensively, if you’re willing to do the work. Since only 1/6th of my comments were actually allowed to keep their links, and since the comments were very well-written, appropriate comments related to the posts, it seems that many blog owners just don’t like to see keyword links in place of the “name” field and will promptly delete the comments or remove the link from the name.
However, once you find the blogs that do let you keep those kinds of comments, you can greatly reduce your workload by posting only to those blogs.
So on a scale of 1 to 10, I’d give this method of getting links a 6. Worth the work, but only if you’re willing to do the upfront legwork required to discover where your comments are worth posting.
