WordPress out of the box is already technically quite a good platform for SEO. This was true when Joost wrote his original WordPress SEO article in 2008 (updated every few months) and it’s still true today, but that doesn’t mean you can’t improve it further! This plugin is written from the ground up by Joost de Valk and his team at Yoast to improve your site’s SEO on all needed aspects. While this Yoast SEO plugin goes the extra mile to take care of all the technical optimization, more on that below, it first and foremost helps you write better content. Yoast SEO forces you to choose a focus keyword when you’re writing your articles, and then makes sure you use that focus keyword everywhere.
The Yoast team does not always provide active support for the Yoast SEO plugin on the WordPress.org forums. One-on-one email support is available to people who bought the Premium Yoast SEO plugin only.
Note that the Premium SEO plugin has several extra features too, including the option to have multiple focus keywords and a redirect manager, so it might be well worth your investment!
You should also check out the Yoast Local SEO, Yoast News SEO and Yoast Video SEO extensions to Yoast SEO. These of course come with support too.
Bug reports for Yoast SEO are welcomed on GitHub. Please note GitHub is not a support forum, and issues that aren’t properly qualified as bugs will be closed.
Write better content with Yoast SEO
Using the snippet preview, you can see a rendering of what your post or page will look like in the search results, whether your title is too long or too short, and whether your meta description makes sense in the context of a search result. This way the plugin will help you not only increase rankings but also increase the click through rate for organic search results.
The Yoast SEO plugins Page Analysis functionality checks simple things you’re bound to forget. It checks, for instance, if you have images in your post and whether they have an alt tag containing the focus keyword for that post. It also checks whether your posts are long enough, whether you’ve written a meta description and if that meta description contains your focus keyword, if you’ve used any subheadings within your post, etc. etc.
The plugin alsgruo allows you to write meta titles and descriptions for all your category, tag and custom taxonomy archives, giving you the option to further optimize those pages.
Combined, this plugin makes sure that your content is the type of content search engines will love!
Technical WordPress Search Engine Optimization
While out of the box WordPress is pretty good for SEO, it needs some tweaks here and there. This Yoast SEO plugin guides you through some of the settings needed, for instance by reminding you to enable pretty permalinks. But it also goes beyond that, by automatically optimizing and inserting the meta tags and link elements that Google and other search engines like so much:
Meta & Link Elements
With the Yoast SEO plugin you can control which pages Google shows in its search results and which pages it doesn’t show. By default, it will tell search engines to index all of your pages, including category and tag archives, but to only show the first pages in the search results. It’s not very useful for a user to end up on the third page of your “personal” category, right?
WordPress itself only shows canonical link elements on single pages, but Yoast SEO makes it output canonical link elements everywhere. Google has recently announced they would also use rel=”next” and rel=”prev” link elements in the head section of your paginated archives. This plugin adds those automatically. See this post for more info.
The Yoast SEO plugin has the most advanced XML Sitemaps functionality in any WordPress plugin. Once you check the box, it automatically creates XML sitemaps and notifies Google & Bing of the sitemaps’ existence. These XML sitemaps include the images in your posts & pages too, so that your images may be found better in the search engines too.
These XML Sitemaps will even work on large sites, because of how they’re created, using one index sitemap that links to sub-sitemaps for each 1,000 posts. They will also work with custom post types and custom taxonomies automatically, while giving you the option to remove those from the XML sitemap should you wish to.
Because of using XSL stylesheets for these XML Sitemaps, the XML sitemaps are easily readable for the human eye too, so you can spot things that shouldn’t be in there.
Are you being outranked by scrapers? Instead of cursing at them, use them to your advantage! By automatically adding a link to your RSS feed pointing back to the original article, you’re telling the search engine where they should be looking for the original. This way, the Yoast SEO plugin increases your own chance of ranking for your chosen keywords and gets rid of scrapers in one go!
If your theme is compatible, and themes based on for instance Genesis or by WooThemes often are, you can use the built-in Breadcrumbs functionality. This allows you to create an easy navigation that is great for both users and search engines, and will support the search engines in understanding the structure of your site.
Making your theme compatible isn’t hard either, check these instructions.
Edit your .htaccess and robots.txt file
Using the built-in file editor, you can edit your WordPress blog’s .htaccess and robots.txt file, giving you direct access to the two most powerful files, from an SEO perspective, in your WordPress install.
SEO and Social Media are heavily intertwined. That’s why this plugin also comes with a Facebook OpenGraph implementation and will soon also support Google+ sharing tags.
The Yoast SEO plugin, unlike some others, is fully Multi-Site compatible. The XML Sitemaps work fine in all setups and you even have the option, in the Network settings, to copy the settings from one blog to another, or make blogs default to the settings for a specific blog.
Import & Export functionality
If you have multiple blogs, setting up plugins like this one on all of them might seem like a daunting task. Except that it’s not, because what you can do is simple: you set up the plugin once. You then export your settings and simply import them on all your other sites. It’s that simple!
Import functionality for other WordPress SEO plugins
If you’ve used All In One SEO Pack or HeadSpace2 before using this plugin, you might want to import all your old titles and descriptions. You can do that easily using the built-in import functionality. There’s also import functionality for some of the older Yoast plugins, like Robots Meta and RSS footer.
Should you have a need to import from another SEO plugin to Yoast SEO, or from a theme like Genesis or Thesis, you can use the SEO Data Transporter plugin, which will easily convert your SEO meta data from and to a whole set of plugins like Platinum SEO, SEO Ultimate, Greg’s High Performance SEO, and themes like Headway, Hybrid, WooFramework, Catalyst etc.
