Matt Cutts has some great words of wisdom for bloggers and website owners in this video on how technical you should get in content and blog posts. You can watch the video at YouTube.
In a nutshell, here are the takeaways on this important topic.
1. Clarity of what you write for your website or blog really matters to Google as it will determine relevancy and what queries your content will match in the Google index.
2. If you cannot make the content easy for people to understand then you do not really understand the content yourself. Matt says this not me! This does not mean that you need to “dumb down” what you write, but content should be informative and written in a manner that attracts those that may not have the depth of experience on a topic to your site to learn more.
3. There will always be a special place for higher level content on a topic but as far as Google is concerned the broader the appeal the better your placement will be.
4. When you make your content too technical or statistical heavy you lose the understandability of your content unless your audience is particularly coming to you for higher level information. Matt Cutts says err on the side of clarity and I say, write for the high school graduate in the bulk of your writing.
