You can use this module to specify a <title> tag that is different from the H1 title of the page. Title tags are an essential element for on-page SEO.
Taxonomy essentially creates tags that can be used to categorize pages and posts. It also can create a new page for taxonomy terms, if you use terms that you want to rank for, having a page devoted to that term can boost your rankings.
Appropriate and unique meta descriptions are key in improving your rankings on the top search engines such as Google and Yahoo! You can also input meta keywords here which are still used in search results by some search engines like Ask.com
One simple button on your pages and posts allows users to tag your site on a variety of social networks. More bookmarks equals more internal links and better rankings.

One-stop-shop for 301 redirects and other redirects you might need.
This creates a valid sitemap for the website, and when submitted to search engines, can get your site indexed faster and crawled more often.
A regularly updated blog is included in any good SEO campaign. Continuous updates to your blog keep spiders crawling your site and can engage users to keep your traffic levels high.
