After some abstenence on the SEO Sector i visited Google Webmaster Tools,
First thing i did was adding one of my domains.
One thing you need to do after adding a site is verify it ? There are 2 possibilities to do that.
One is uploading a File the Other one is Adding a Metatag to your site.
I decided for the Metatag which is lookling like this
<meta name="verify-v1" content="Ie1Yq6cHpdij9utSIedj3hIUOEI4d3S3Rh7QOHXUk=" />
After you have verified your site you can remove the Meta tag or file again.
First thing i tried out was the Web Crawl which gives you information about indexed HTTP Errors and Indexed not found faults.
What i found there were about 34 Indexed URLS which were pointing to an very old version of a gallery script,
so i decided to add an new role to my .htaccess file
RewriteCond %{REQUEST_URI} /oldgallery.php(.*)$
RewriteRule ^oldgallery.php$ /gallyery/newgallery.php [R=301,L]
I wasn´t able to rewrite the old query string so i, cause it seems a bit complicated changing ?oldvar=value to ?newvar=value by an RewriteRule after searching arround for one hour and finding some none working solutions i decided to save time and just make a change to my PHP script, but i ll keep on searching.
