Hello, First of all, this is just my opinion, so for sure any user can say that he used X plugin and it dropped his blog to the end of Google. Anyway, based on my own experiencie, there are 5 plugins that you need in WordPress if you want to create a good-looking site for Google, Yahoo, Bing and etc. 1. - SEO Friendly Images. Bored of adding manually the TITLE and the ALT Title of every image that you post? This plugins adds automatically -for example- the title of the entry to the tags of the image. I've configured it with %title, but you can also add the tags, the category and any other text -beware of over-optimization!-.

This plugin automatically adds links to your entries and you can configure it just exactly as you need. Download link: http: // wordpress. org/extend/plugins/seo-automatic-links/ 3. - WordPress SEO.

Okay, you can edit your theme and you can create a mobile version just with your skills. But if you only need some mobile-version of your site, this plugin is the best option.
