Adwords Analysis Part I

I just did an Adwords analysis on my personal blog www.htchan.com.  To my disappointment, it returned keywords mainly related to blog and weblog (see picture).  I believe the major reason of that was my poor choice of blog name and description.  My guess is that Google puts a quite heavy weight on a blog's name and catchphrase when deciding the adwords as they show up basically in every page.  Another reason of the poor result could be due to the fact that I had quite a few postings of technologies throughout.  That is probably one major thing that I was different from my teammates.  I guess one lesson learned from here is importance of having a focused topic for one's website.  Once Google thinks your blog is of certain kind of topic, it will take a long time for it to update the impression (it has to crawl your website again).  More important, we just don't know the algorithm it uses and it may cache your site's old content and thus you can never 100% refresh its impression to your site.  For example, this entry is already hurting my blog's relevance to Ann Arbor food.  I have updated my blog name and catchphrase to include "Ann Arbor Food".  Also, I plan to add more food postings to dilute my technology contents.  Hopefully, the right adwords will appear soon.
