5 of the Best Seo Plugins for WordPress

With more than 180 million blogs in existence, it can be difficult for people to find your content on the Internet. The key to successfully getting users onto your blog is with search engine optimization (SEO). SEO is the process of optimising your Blog for search engines with the aim of getting a high listing on the search results pages.

You can blog on a regularly basis with quality content but if you don’t have good SEO, then odds are you won’t have many readers. WordPress, the leading bloging platform takes Seo very seriously and provides a plugin community that values SEO and has developed a number of plugins to help. Plugins allows users to extend their WordPress blogs abilities beyond the features that are part of the base install; WordPress has a database of over 18,000 plugins with different features.
The five plugins listed below will increase traffic to your blog. They will enable you choose the right tags, tell search robots what to work on, optimize your post titles and more.
1. Automatic SEO Links – Automatic SEO Links allows you to choose a word or phrase for automatic linking, both internal and external, set anchor text, choose if it should be “nofollow” or not, and more.

2. Google XML Sitemaps – An important tool in any blogger’s SEO tools. While the name only mentions “Google,” this plugin creates an XML-sitemap that can be read by Ask, MSN and Yahoo also.

3. Nofollow Case by Case – This plugin allows you to strip the “nofollow” command from your comments, and then you can apply it to only the comments you don’t wish to support.

4. SEO for Paged Comments – With the introduction of paged comments in WordPress 2.7, there was a potential problem with search engines thinking you had duplicate content as the post would appear on each page.

5. SEO friendly and HTML valid subheadings – Some themes for WordPress will confuse your sub-header tags based on the page they are to be displayed on, but this plugin will automatically reset them to make them more SEO friendly by moving them down one spot in the hierarchical tree. In other words, h2 becomes h3, h3 becomes h4 and so on.
