Functionality
Gravity Forms: Makes form management easier than ever. Especially useful for sites that publish user-generated content.
Duplicate Post Checker: Will check for similar posts that already exist. Great for sites that publish jokes, quotes, poems, etc.
Viper’s Video Quicktags: If you embed videos into your posts, you’ll definitely want this plugin. Once the plugin is installed, you can configure how the videos are displayed (width, height, alignment, etc.). Then all you need to do is paste the url (that the video is located at), and it will show up in your post.
Yet Another Related Posts Plugin: Uses an advanced algorithm to show related articles (from your blog) for each post. The plugin also caches the related posts that are shown, which significantly improves performance over other related posts plugins.
WP-Polls: Allows you to place a poll on your site. Easily customized via templates and css styles.
Feedburner Feedsmith: Detects all the ways to access your feed, and redirects them to your Feedburner feed (allowing you to track all of your subscribers).
WPtouch iPhone Theme: Transforms your blog into an iPhone application-style theme when viewed from popular smartphones (iPhone, Android, Blackberry, Palm Pre, etc.).
Monetizing
OiOPublisher: Allows you to sell your own advertising through a fully automated system. Also makes it easy to sell digital products.
Amazon Auto Affiliate Linker: Automatically adds your Amazon affiliate id to every link pointing to Amazon from your blog.
Performance
WP Super Cache: This plugin generates static html files from your dynamic blog; dramatically reducing server load during high traffic spikes.
Security
WP Security Scan: Scans your Wordpress installation for security vulnerabilities and suggests corrective actions.
Limit Login Attempts: Limits the number of login attempts from an IP address, making a brute-force attack difficult. The plugin will also log the activity, and notify you via email if you choose.
Akismet: Checks your comments against the Akismet web service to prevent spam from getting published. Also allows you to review the spam it catches.
RSS Footer: Makes it easy to add a line of content to the beginning or the end of all the articles in your feed. This is great for adding a link back to your site (to counter scraper sites that are stealing your content).
SEO
All-in-One SEO Pack: A must have plugin for SEO. Here are just a few actions that are easily performed using this plugin:
- Setup canonical urls
- Rewrite titles
- Set meta description and keywords
- Optimize title format
- Enable noindex on specific pages, to avoid duplicate content penalties
SEO Friendly Images: Automatically updates images with ALT and TITLE attributes.
SEO Smart Links: Allows you to interlink posts on your site, or link to affiliate sites through keywords that you specify. When these words appear in your posts, they will automatically link to the url you set.
Google XML Sitemaps: Generates a XML-Sitemap of your site. Supported by Google, Yahoo, MSN, and Ask – this will help search engines crawl your site.
More Useful WordPress Plugins
Come on, you didn’t expect us to stop there did you? That would only leave you wanting more. Which is exactly why we’ve added 10 more plugins to the list.
Why didn’t these make the top list? To maintain performance, we believe you should aim to keep plugins to a minimum. Additional plugins mean longer load times, stress on the server, the possibility of complicated upgrades, and maybe even trouble with your web host (depending on the provider).
We also took into consideration how useful the plugins are, and how easy they would be to replace by simple theme revisions, or manual actions. In other words, if the plugins only added a minor convenience, we preferred to avoid the unnecessary bloat.
Even so, many bloggers will find these plugins useful, so we’ve added them to cater to everyone.
WP-DBManager: Allows you to optimize, repair, and backup your database.
Why it didn’t make the top list: We prefer doing a manual backup of the entire site (not just the database).
W3 Total Cache: The ultimate plugin to improve server performance; this plugin has it all. Seriously the author thought of everything.
Why it didn’t make the top list: Unless you’re advanced in dealing with the backend of your site, you won’t be able to take advantage of many of the features offered in this plugin. You’d be better off using the WP Super Cache plugin mentioned above.
Robots Meta: Easily add meta robot tags to Wordpress pages.
Why it didn’t make the top list: All-in-One SEO Pack already gives you the ability to noindex the important stuff. This plugin just goes overboard in our opinion.
Breadcrumb NavXT: Generates locational breadcrumb trails for your blog.
Why it didn’t make the top list: Breadcrumb navigation is situational. In fact, some studies show that breadcrumb navigation can actually confuse the user. Even so, breadcrumb nvaigation is easy enough to implement without a plugin if needed.
SEO Slugs: Removes common words (the, in, a, what, you, can) from post slugs to improve search engine optimization.
Why it didn’t make the top list: We’re not convinced that this is going to make a big difference in your rankings.
We’ll be adding more plugins to the list soon. Be sure to bookmark this page!
