WordPress plugins easily add new features and increase the functionality of your site, usually with just a few mouse clicks.
Below is a list of my favorite plugins that we’re currently using on this and our other wordpress sites.
Thank Me Later
Sends a thank you e-mail to anyone that leaves a comment on your blog.
Creates an alternate theme for visitors using mobile devices to view your site.
WP Super Cache
Caches your posts and pages so that each page doesn’t have to be dynamically generated for every single page view. Makes your site load a lot faster and cuts down on server load
SEO Smart Links
Automatically links keywords and phrases in your posts to other posts. Fully customizable so that you can pick what links to where.
SEO Friendly Images
Adds alt tags and titles to all your images in your posts.
Contact Form 7
Lets you create custom contact forms to use in your pages or posts.
Subscribe to Comments http://wordpress.org/extend/plugins/subscribe-to-comments/
Notifies a commenter when there is a reply to their comment. This is great for keeping a discussion going in your comments area and for getting return visits to your site.
Update: Subscribe to Comments Reloaded!
Like the old one but with more features, less bugs and other cool stuff that makes it worth the “reloaded” title.
All in one SEO pack
Lots of SEO options to choose from to make your site more attractive to the search engines.
If you get a premium theme (highly recommended) then a lot of the features in this plug in will already be included and you shouldn’t need it.
Google XML Sitemaps
This creates a sitemap for your site, keeps it updated and submits it to google. Basically it lets google know what and where all the content on your site is so it can better list your content in the search results.
Adds social buttons to your posts and your RSS feed.
Add a poll to a post or page.
WP Auto Tagger
Uses Yahoo API to scan your post and suggest tags to use.
Tweet Old Post
Randomly pics old posts and tweets them on twitter.
A very popular plugin for letting commenters place a link back to the last post on thier own site.
No 404 Errors
Gets rid of 404 errors from missing or moved pages on your site by redirecting to a page of your choosing.
