Any serious SEO consultant worth their salt will tell you that they rely on a suite of SEO tools. If you ask them which ones they use, there's going to be many references to popular, unique tools like SEOmoz's Page Strength or SEO Book's SEO for Firefox extension. But then many sites offers tools that provide the same functionality, and SEO experts will cite a variety of places for such common things as rank checking or keyword research.
SEO ROI Services' tools are not me-too tools. Either a tool will be completely original, or it will improve the functionality of those tools already in existence. Bookmark this page and check back regularly as more tools are added and others updated.
This tool allows you to set keywords to automatically link to a given page. Whenever that keyword appears on your blog, it will link to the page that you designated, like Wikipedia (which ranks pretty well...). The result is that you build link value to your important pages and rank them higher.
In order to increase conversions, minisites feature about pages, contact pages and other "credibility" type pages. The problem is that with a standard Wordpress installation, these standard credibility pages link to all the landing pages on the site. This makes for a weird user experience for visitors, decreasing credibility and decreasing conversions.
The 1 Minisite, 10 Landing Pages Plugin solves that problem by controlling the navigation a visitor sees, based on a cookie placed on his computer. To the visitor, it only looks like there's one landing page.
