Google Blog Search is a new tool that is gaining popularity on the Internet lately. The Blog Search might also be a good source of visitors if your blog rank on the first positions for specific keywords, but what factors does Google take into account to elaborate the search results?

The “Seo by the Sea” blog has an interesting article analyzing a new patent from Google that contains some indicators about the positive and negative factors affecting blog ranking, check it out:

Positive Factors:

  • Popularity of the blog (RSS subscriptions)
  • Implied popularity (how many clicks search results get)
  • Inclusion in blogrolls
  • Inclusion in “high quality” blogrolls
  • Tagging of posts (also from users)
  • References to the blog by sources other than blogs
  • Pagerank

Negative Factors:

  • Predictable frequency of posts (short bursts of posts might indicate spam)
  • Content of the blog does not match content of the feed
  • Content includes spam keywords
  • Duplicated content
  • Posts have all the same size
  • Link distribution of the blog
  • Posts primarily link to one page or site

    Please, if it isn’t much of a trouble, could you define what “spam tags” look like.

    Does that mean tags that are used over and over again, or what?

    You weren’t really clear on that…

    I assume on the tagging that they are talking about tags and such that point to your blog.

    1. I think Google uses the data from Google Reader and Google Personalized homepage and extrapolate the results.

    2. I was curious about this one as well. Pehaps Google considers not only the tags present on your blog but also tags on other posts that are linkind to your blog.

    I am not sure how one would implement a “tagging” system to allow users to tag your stuff, and I am not sure if that would be a good thing either 🙂

    Interesting points Daniel. I was wondering about 2 of the positive things:

    1 : RSS Subscriptions : Do you know how does Google access this information? Is it counting the number of hits to the internal RSS feeds on a site, or does it have access to the information by RSS services like Feedburner?

    2 : Tagging of posts from users : Does Google have a way to find out whether or not a site/blog allows readers to add tags to a post? Also, do you know of a way to allow users to add tags to a site? I am using the UTW plugin, and as far as I know, it allows only site/blog owners with WP admin area access to add tags to a post.

    Thanks for sharing. 🙂

    I cannot see that either. I agree with you and jpmelos. The content is much more important to evaluate. The size or frequency aspect makes no sense to me.

  • Daniel

    I also find not complete clear 2 negative factors, the post size and the frequency of posts. Most established blogs have a very predictable post frequency, just like spam blogs… so I can’t see how they are going to figure the difference.

  • Manta SEO Solutions

    very interesting points. I guess the positive factors all rely on how well you’ve marketed your blog. The age of you blog plays a role too but I guess that the quality of your content is most important which should help with getting your blog “blogrolled” much quicker.

    If people like your content, then they’ll bookmark it o link to it…

  • jpmelos

    Where’s the point in the “Negative factor” of “Posts have all the same size”? If they want find spam and/or duplicate content, they should analyze content instead of size… That sounds too obvious to me…
