there are so many factors that govern when google will visit like santa claus that it is not funny. So, bear in mind this will take some time.
I will advise the following simple SEO tips for wordpress:
Firstly, create yourself a robots.txt file. The amount of sites out there trying to raise their ranking without one is ridiculous.
So, create a file and name it robots.txt and place this in the root directory of your site.
If you want google and all other robots to crawl like crazy put the following in the file:
User-agent: *
Disallow:
If you want a robot to not index a particular part of the site, then your robots.txt should have something like:
User-agent: *
Disallow: /images/
Disallow: /mysecretfile.html
etc etc etc....
in wordpress speak, this might be a way you wish to go:
Disallow: /wp-admin
Disallow: /wp-includes
Disallow: /wp-content/plugins
Disallow: /wp-content/cache
Disallow: /wp-content/themes
Disallow: /trackback
Disallow: /cgi-bin
Disallow: /search
Disallow: /feed
Disallow: /rss
Disallow: /comments/feed
Disallow: /feed/$
Disallow: /*/feed/$
Disallow: /*/feed/rss/$
Disallow: /*/trackback/$
Now, I recommend two plugins for your site:
SEO Title Tag
Google XML Sitemaps
Both very easy to install and configure. The title tag will allow you to configure your own more search-engine-friendly titles for pages. This will help the search results...
The sitemap is self-explanatory.
I would also strongly recommend turning on permalinks. the ?=1 stuff is not search engine friendly really.
And of course, you will need descriptive, well designed text on your site to cater towards possible search strings. People are never going to search for your site directly if they don't know it exists already.
Remember that an image heavy site is not search-engine friendly. Bots crawl text primarily, alt and title tags for images must be put in.
Outside of those sorts of things.. the only other way you can really boost your page ranking, is by having sites link to you. The higher the page ranking of the site linking to you, the more it will help you.
So get on out and market the bejesus out of your slice of the web :)
hope that helps.
