It is very important to make sure your homepage is as well-represented on Google as possible.
Most people tend to think that if you get a high placement on Google for your chosen keyword(s) that it is enough. It is also very important to ensure what the searchers see on Google is relevant.
Not only is the title-text very important, but the text beneath your link is extremely important as well. This text is scanned by the people that search on Google, and if your title did not convince them to come to your homepage, the description text will be the final chance.
In the following screen shot you can see how Google first indexed the front page of this website.
As you can see, the text is hardly convincing for people to click on, and to fix that, there are several plugins available to help. For this website, I use HeadSpace 2, but I also use All in One SEO Pack and Platinum SEO Pack, especially for sites that I want to automate as much as possible, as their default settings work great straight away.
There are several problems with above screen shot:
First of all, “myWordPress” is in the front of the title. This is not very relevant, since I am looking to get traffic from the search engines, and the name of the homepage should be in the back of the title.
Furthermore, “Tip:” and “Posted by admin on 03 21st, 2009” and the “No comments”, is not at all relevant.
Google decides by themselves if they want to use the meta description you supply, or if they take part of the homepage instead. So, if you install one of above plugins, check back on Google after a while.
As you can see in the following screen shot, Google updated the listing after a few days, and it is now a lot more relevant and appealing to the people searching on Google.
It can take a while before Google updates the description of your homepage, so do not worry if it does not happen immediately.
