I recently launched my first website, using Wordpress, and submitted the sitemap to Google. I have an about, contact us and sitemap page. Since Wordpress(or at least my particular review-style theme) doesn't really allow you to edit the Home page, I'm not able to add any text to it and thusly Google is not able to extract any information on what it thinks my website is about. Because of this, whenever I search for my website in Google the little snippet of information that comes up is only the domain name repeated a few times and the line 'Powered by Wordpress'.
I thought maybe uploading a Sitemap would allow Google to extract the information from my 'About' page, but I guess not. Since my theme is review-style, the Home page is simply a list of all of the products and I'm not able to delete it just to re-create one of my own. Is there anything I can do to somehow alert Google what my sites about and allow it to summarize my website correctly?
Thanks in advance,
