1. The Command "Site"
Not sure if all your pages are being seen by Google? Search for your site's address after the command "site", like [site:example.com].
When you see your pages in the results, check your snippet content and page titles. Include information that matches the topic of a particular page.
3. Image Search
Label your images appropriately. Users searching in Google Image Search will more easily find the image on your site.
Don't miss out on potential traffic because of [001.jpg] instead of [NintendoWii.jpg].
Manage your SiteLinks.
Your most valuable links may not be the ones that Google chooses as SiteLinks, so remember you can remove any that you don't think users will find useful.
