On this page you will find the best Wordpress plugins, ever. These are essential installations - but remember, Worpdress runs faster with fewer plugins, so don't be tempted to install them all!
Backup and Optimize
W3 Total Cache
The ultimate swiss-army knife of caching, from the basic page caching (keeping a static copy of the page), to CSS/JS/HTML minification (making your files smaller), as well as handling uploads to a Content Delivery Network.
If W3TC is too much for you, SuperCache is the answer. Very simply, it makes static HTML files to serve users, and much fewer settings to break.
Backup Buddy Premium ($75)
Expensive, but the only WordPress plugin that can truly handle both file and database backups easily. Only for pro-bloggers though at that price, but a license lasts a lifetime. Site migration too. ($75 for 2 site license)
Migrate an entire website from one domain to another, without messing around in the database, for free.
Vaultpress Premium ($15)
Another premium backup service from the guys that created WordPress, so you know it's rock solid. ($15 per month per site)
CloudFlare Caching Service
Though not really a plugin, this is a free service that works fantastically with WordPress to reduce the amount of spam requests for your page and cache certain resources in local CDNs around the world. Results in significant speed increases. Well worth it but requires you to adjust the name servers for your domain so can be a little tricky to set up.
Optimizes the database by running the optimize SQL command, removing post revisions, spam and unapproved comments. It's essential if you don't manually manage your database or run your own optimization scripts. Also includes functionality to rename users, useful for changing the default admin user.
From the WebSite Defender guys, this gives you a thorough security check and make a number of small adjustments to harden your Wp install, such as hiding the version number. Also available as an online service.
Monitor your site 404 errors and create simple 301 redirects easy to keep the Google link juice flowing and your readers free from 404 pages. Find what's 404ing, redirect it, easy.
Broken Link Checker
Dealing with broken links can be pain if you're waiting for readers to report them - get ahead of the game with this plugin and automatically check all the sites you've linked to before they become a problem.
This won't work for everyone's setup, but it's a fairly comprehensive free solution, and one of the best WordPress plugins for backups if you are lucky enough to get it working; includes email backups, Amazon S3, Dropbox; and does a full file and DB backup, not just post export.
Wordpress Backup To Dropbox
A simple solution for smaller sites; this plugin does what it says on the packet.
A complete (and free) WordPress security suite - firewall, malware scanning, strong password enforcement, plugin and theme file repairs, real time traffic overview. Just, wow.
Search Engine Optimisation
Wordpress SEO by Yoast
Widely regarded as the SEO plugin for WordPress. It has an extensive feature set and rave reviews. Give it a whirl, there are alternatives though. Includes XML sitemap features.
Another extensive feature set - this one has a 404 error tracker and well as link cloaking for your affiliate links, as well as the standard features. Each module can be disabled as required, so scales with your needs. Quite heavy when fully enabled though.
Google XML Sitemaps
Creates a site map for you to submit to Google and automatically updates it when you post new content. Essential for getting indexed quickly and accurately.
SEO Friendly Images
Adds ALT and TITLE meta tags to your images so you can start getting valuable Google Images traffic.
The only easy way to add robots meta tags to specific pages, search results or feeds. Includes options for deindexing from directories and search engine specific tags. Also lets you edit htaccess and robots.txt from within the WordPress admin.
Social and Commenting
Thank Me Later
Automatically sends a follow-up email to anyone who leaves a comment at your blog, thanking them for taking the time to comment and encouraging follow up visits.
OnePress Social Locker
Give visitors a reason to like or tweet your page by locking valuable content - this is a quick an easy 'pay with a like' system.
A full replacement comment system for WordPress offering a range of login options, share buttons, and serious spam protection. Syncs with your WordPress database to ensure you don't lose any should you decide it's not for you. Restricts your ability to add other commenting functionality and plugins though, beyond what Disqus provides.
Full set of social sharing buttons in a variety of styles - a vertical floating box is usually quite popular.
Make your own social spam with this auto-posting utility for a variety of social networks. Warning: may cause rapid loss of friends!
Comes with WordPress, but if you haven't activated and added an API key yet, you're missing out. It really does stop the hordes of spam comments that come every hour.
Creates a persistent slide-on sidebar widget you can fill with links to all your social profiles. Essential if you have a lot of accounts, but for one or two, just paste them onto a regular text sidebar widget.
A revolutionary real-time commenting system with added social login features, CommentLuv-like links to users latest blog posts, user profiles that encourage interaction and more. Definately worth considering to replace your standard WordPress comments!
Another floaty share bar, but this one has a lovely icon set and counter which brings up the actual share button when a user hovers over it. Keeps those ugly native buttons off your posts.
Shareaholic (formerly SexyBookmarks)
An attractive set of social bookmarking buttons with share count (except for G+), a content recommendation widget, and analytics.

Replaces the next/previous buttons with good looking paginated buttons. Customizable, and absolutely essential.
If you edit your post a lot, each autosave will result in a new revision stored in the database. Keep those under control by limiting them with this plugin.

Redirects your main feed to the Feedburner site. This reduces the load on your server as well as adding a host of additional features.
What Would Seth Godin Do
Odd name for a plugin, but it creates a welcome box for new users visiting the site. Disappears by default after the 5th visit. Use the box to encourage signup with the newsletter, or RSS feed, or just a personal greeting.
Enhance the search box with results as the user types. Uses a third party relevancy engine, so you'll get better search results than the basic WordPress engine as well - and the option to manually override results to your liking for specific searches.

Linktrackr Premium ($9)
Essential for anyone using affiliate marketing or conversion pages, this plugin performs link cloaking and A/B testing for various conversion page designs. Also includes a viral makreting (sharebar type) module. Full stats and dashboard, various plans available from $9/month.
Gravity Forms Premium ($39)
Expensive if you just need a form, but the feature set is incredible and the name deceiving. Multi-step, logic, limiting entries for competitions, even a full ordering system.
An enhanced version of the built-in WYSIWYG editor that gives you a customizable array of extra features, such as being able to add HTML tables. Essential if you use the standard editor but find it a little frustrating.
Dynamically adjust which widgets appear where - Widgets Controller uses a simple interface with checkboxes (rather than the similar and previously Widget Logic, which needed an understanding on conditional coding).
Syntax Highlighter Evolved
Essential for anyone who blogs about code, programming or web development - this plugin gives you an attractive and functional highlighted code block with optional line numbers. You might prefer Google Syntax Highlighter though, so check that out too - both are good.
Allows you create additional user levels, as well as crucially blocking actual post content from being viewed by users not of a certain level - so you can set up a premium area of your site for paying users and require membership. I don't recommend this tactic, but this is one of the best WordPress plugins that will handle it all for you smoothly.
Running a multilingual site with multiple translators is an incredibly difficult task; this plugin is absolutely essential if you plan on doing so in WordPress. No other multilingual plugins come close - but this comes at a price of $80 for the full version.

A premium drag'n'drop form builder, capable of building much more than your simple contact form. If you hope to gather lots of data or do surveys, this is probably the plugin you're after.
Fluid Video Embeds
Simple plugin to fix WordPress' auto-embed video sizes and keep their aspect ratio. Nothing difficult to configure here; just install and activate if videos are a big part of your blog.
Simply beautiful sliders, with support for a huge range of content and not just images; also capable of pulling more content from external sources like your YouTube channel or Flickr. Very customisable too, and a variety of prebuilt themes (lens). The free version is a little limited, but a full single site licence can be had for $49 to unlock everything and remove the watermark.
Allow PHP in Posts and Pages
If you need to add PHP functionality to WordPress posts and pages and don't want to alter the theme templates, install this plugin.

Ultimate Coming Soon Page
Develop and perform changes on your live site by using this plugin to keep out the masses with an Under Construction or Coming Soon message. Looks great, and even allows you to gather email addresses, ready for launch
Contact Form 7
A very popular contact form tool, this is more basic than others but nevertheless effective, dispensing with bells and whistles for core contact form effectiveness.
If you have multiple contributors on your blog, Edit Flow is the tool you need. Enables you to manage users in groups, set custom statuses for articles, get notifications via email when posts are ready to be published and even manage article budgets.
Custom Login Lite
Dispense with the WordPress branding on the login screen - use this plugin to display your website's own logo. Improves perception with commenters and contributors, producing a polished, professional look.
It's free, feature rich, widely supported and used by many successful shops. Additional features and plugins can be pricey, but the basic feature set should be enough for most small sites.
Shopp Premium ($55)
Payments modules and other plugin functionality cost extra; but with rock solid support and a much cleaner backend interface than the free solutions. If you're serious about eCommerce on WordPress, it should be a negligible expense for the peace of mind and support offered with a premium plugin.
Photography and Galleries
The built-in gallery and photo management in WordPress isn't ideal - this plugin creates a whole new gallery section to manage your photos, disassociating them from posts. You can then embed albums or galleries in posts or collect all your images on a single page. An extensive plugin in and of itself, you can also download plugins for NextGen Gallery to extend functionality further.
Smush.it is an image optimizer service from Yahoo that can reduce the size of your images by around 10-40% without any loss in quality, and with this plugin your images will automatically be run through the service (they're still hosted on your server though). There's also a bulk option to do all your previously uploaded images too. If your site is image heavy, this is absolute must and pretty amazing stuff really. (Note: it doesn't work on images over 1 MB).
Get Me Cooking
A rich-markup compatible recipe plugin; you can also submit your recipes to feature on the getmecooking.com recipe directory!
Leaflet Maps Marker
Need to add a map to your blog? Then you need this plugin. It's 100% free and give you a huge range of mapping providers and icons to choose from; even supports some augmented reality viewers. Then just add the maps to your page with shortcode. It's an immense and complicated plugin, but you should be able to figure it out.
Any blog hosting a podcast should have used the podPress plugin, which automatically produces feeds, enables you to create iTunes-compatible metadata and offers a slick, embeddable media player - it even gives detailed statistics!
