There is little doubt that WordPress blogs are some of the most favored blogs by the search engine spiders. Because of the platform’s popularity, developers are constantly coming up with new plugins to make your WordPress experience better. Last time we looked at some of the most popular plugins used by many bloggers. This post continues that list with a few more of the biggies you don’t want to miss.

If you want your readers to be able to contact you (and hire you!) you need to provide some sort of contact form on your blog. Contact Form 7 is one of the easiest, most flexible content form plugins around. You can manage several contact forms and customize your forms so you get the information you need without overwhelming your reader.

Your blog is all about developing relationships with your readers, so in addition to a contact form, you want to make it easy for them to interact with you. Social media is a great way to carry on the conversation. Add a WPFollowMe plugin so your readers can follow you on Twitter with a mouse click. You can add your tweets to your blog with TweetMyBlog or a number of other plugins and widgets.

If Facebook is your meeting place, there are plugins for that as well. Try WP-Facebook Connect to add Facebook functionality to your blog. Add To Facebook is another plugin that will add your posts to your Facebook account through a footer link. The Facebook Dashboard Widget lets you see all your friends Facebook updates from the Admin page of your blog, so YOU can keep in touch while you’re working without needing to head over to Facebook.

Because your readers love social media too, one of the best plugins you can put on your blog is ShareThis. ShareThis offers your readers a number of social networking and bookmarking sites they can share your posts to with a simple click. Why not boost your traffic through the power of your readers by making it easy for them to share your words of wisdom? Another great sharing plugin for your readers is SexyBookmarks. Don’t let the name scare you off- there’s nothing seedy going on here. This plugin just offers your readers the ability to share your posts in a cute friendly icon sort of way.

Running a blog is all about interacting with your readers in order to build a relationship with them. That relationship is what will lead to bigger sales and business growth for your blog. When you take advantage of some these plugins on your WordPress blog, you make relationship building easier for you and your readers. Combine relationship building techniques with great SEO techniques and you’ll find your blog traffic, readership and subscription lists growing out of sight in no time.
