I recommend all bloggers setup Akismet because it’s the best solution for managing comment spam.
It’s been developed by the company who owns WordPress, Automattic, and is one of the most essential plugins that every blogger should install.
Allow REL= and HTML in Author Bios
This plugin enables you to add the code in order to link your Google + profile picture to your posts so your face appears next to your url’s indexed in Google’s search results.
The functions contained within this plugin allow you to setup & verify author ownership of your sites post content.
BWP Google XML Sitemaps
The reason i use this sitemap is because it works perfectly on the server which i host WP Sites.
The sitemap included in the WordPress Seo by Yoast plugin doesn’t currently work properly on all theme’s which is why i have deactivated it and installed this plugin.
Another reason is this plugin lowers the resources used by other sitemap plugins like Google’s XML Sitemap plugin.
FeedBurner FeedSmith Extend
This plugin redirects all feeds to your Feedburner acccount.
It even finds feeds for categories and tags and also redirects them to your account.
Genesis Simple Hooks
One of the many benefits of using the Genesis framework is the plugins which have been specifically developed for this theme framework.
Genesis plugins add more functions on top of the standard framework functions.
Genesis Simple Sidebars
This plugin enables you to easily create and display specific sidebars on different pages of your site.
You can then add different sidebar widgets to specific posts & pages and display different content on these pages.
I only use it on the pages for my video guide to display a custom menu of 24 pages included in the guide.
Displays next and previous posts links on single posts only to enhance navigation for your readers.
This plugin increases page views as it make it easy for your readers to move back and forward to read more posts.
Jetpack by WordPress.com
One of the best plugins for WordPress in my opinion.
Jetpack includes many different modules which can be enabled or disabled depending on your needs.
You’ll need to create and connect Jetpack to a WordPress.com account.
Did you know you can also use some of JetPacks modules as stand alone plugins? This way there’s no need for you to connect to a WordPress.com account.
This plugin works with the native WordPress gallery.
It enables you to select which images you want to include in your galleries out of the images you have uploaded for that particular page or post.
It also allows you to select images for use in multiple galleries within the same post/page.
The easiest way to install a video player in WordPress is to activate Pro Player.
Proplayer is one of the best video player plugins and its free.
This plugin enables you to show videos on your site within minutes without needing any technical knowledge.
The plugin is an enhanced version of JW Player.
Keyword Density Checker
Another essential plugin which i recommend all bloggers use.
The keyword density checker enables you to make sure you don’t stuff your content with too many keywords and risk suffering an over optimization penalty from Google.
This plugin provides the easiest way to check the keyword density of your posts content.
The most complete and comprehensive Seo plugin for WordPress.
One of the reasons i decided to setup WordPress Seo on WP Sites is the snippet Preview. This feature allows you to view the description of the post which is included below each of the url’s you have indexed in Google’s search results.
You can also create custom descriptions for Facebook and Google Plus which are displayed when you share your posts to those networks.
Includes a built in sitemap, 301 redirects and no follow/no index options on all pages and posts.
