With this kind of a sitemap on your blog, it is  easier for the crawlers to see the complete structure of your site instantly and retrieve it more efficiently. The plugin supports most kinds of wordpress generated pages as well as custom URLs. Additionally it notifies all major search engines every time you create a post about the new content.

#7: Redirection

For a range of factors you occasionally need to be able to move a page from one location on your weblog to another, however you are in danger of dropping that web page’s status in search results.  Redirection helps you with your 301 redirects and captures a log of the 404 errors so that you can then work on correcting them – it also sets up an RSS feed for these errors and much more.

301 redirects are mainly used to permanently move a site to a new location. Search engines do not apply penalties to 301 redirects the way they apply them to many other types of redirects. Generally whenever we do a 301 redirect, we need to create a .htaccess file and add the rules inside this file. This plugin simplifies the process and allows us to define these rule very easily without any knowledge of .htaccess.

It is a really important plugin that will help with google search engine optimization – especially so for small business seo – where sometimes companies buy other companies and you don’t want your users to get lots of 404 errors when the sites of these two companies are merged.

#8 SEO Friendly Images

Images can easily be an excellent source of traffic since visitors search for images of various topics. This plugin will help you to ensure that you have “ALT” and “TITLE” tags on all your images so that the search engines can index them correctly.

If these images do not have the ALT and TITLE tags set already, SEO Friendly Images can add them in accordance with the options that you define. Furthermore this makes the post XHTML valid. Adding the ALT tag is a very important part of the search engine optimization process. It describes your image to the search engines and whenever a user is searching for a certain image this tag is the key determining factor for a whether a match is found or not. TITLE attribute play lesser role but is important for visitors as this text will automatically appear in the tooltip when mouse is over the image. A nice addition to your effective seo campagin

#9 Google Positioner

It is critical to know your keywords phrases. This plugin will allow you to track the keywords that are bringing you  searches. It is really worthless to select  a few keywords, then write content for those keywords and hope that all goes well. Search Engine Optimization is not just being optimistic but is more about being proactive and tracing what  works and what does not work.

Once you put the right keywords in the right page, it is very important to keep a record of your keyword performance.  And now with this  plugin it is possible to track your website for your keywords in Google search engine. The main focus is on Google due to the fact that it’s  influence is so much greater then all the other search engines put together.

You should be able to track a particular keyword on a specific page, and hope to have a rising curve, which means that your web page has started to rank better for a certain query.

#10  SEO Slugs

Stop words are generally ignore by most search engines. Most of your post titles have them, but they are meaningless to the search engines. So when you have a post title like this: “What You Can Do Immediately For Higher Rankings” you have a permalink like this: ‘/what-you-can-do-immediately-for-higher-rankings’ but what you really want is for your permalink to look like this: /immediately-higher-rankings.

Blog post titles usually get an h1-h3 heading, which makes them critical for keyword optimization.  SEOSlug will optimize the blog post titles and improve search engine visibility by making edits to the keyword strings. It will remove conjunctions from titles, (words like “as” and “if”) to allow crawlers to more readily crawl main content keywords as a fluid string. This makes it far easier to rank higher and is another example of a cost effective seo technique that you can use for your website.

#11 Cross Linker

This wordpress plugin can automatically hyperlink selected words to a pre-defined URL. The hyperlinking process functions in posts and comments which is given as an option. If youupgrade from a previous version, then please don’t deactivate the original installation of this plugin. Awesome search engine optimization plugin.

#12 Ultimate Tag Warrior

This is really the best tag system for WordPress. With this plugin you can easily use the categories and tag system on your website. It makes it really easy by searching through all the tags you made for the posts.

The greatest challenge is in really in figuring out what tags to use in your wordpress theme to generate the tags. You have a couple of choices : you can use site search tags or Technorati Tags. You can add one or the other or both.

By default, these tags can be added automatically to the end of your posts by choosing that option in your Tags customization panel. You can choose to add Technorati or site search tags or both to the end of your posts. The problem with this is that the plugin just adds the tags to the end of the post.

The automatic tags are wrapped in a span <span class="localtags">. You can style that span, even adding a clear:both to put the tags on their own line, but I found that this doesn’t always work, depending upon your WordPress Theme layout.

You can turn off the automatic functions and manually add tags to your WordPress Theme template files to generate the tags. This works great and you can wrap them in your own style to control the look and placement of the tags.

#13 Landing Sites

Whenever visitors are referred to your web site from a search engine, they are  looking for something specific and often they just  check the page they land on very briefly and then close the window if they don’t find what they were looking for. This plugin helps them by showing them related posts to their search on your blog thereby giving a greater chance at stickiness and reducing your bounce rate.

#16 WP Super-Cache

This plug in contributes to your site speed and it helps your blog load faster. Since search engines are giving greater importance to site speed in their ranking algorithms, this has become an even more important plugin.  The number of pages on your blog that a search engine indexes on a daily basis increases with speed.  If the indexing on each page is a quicker exercise for the spiders, more pages will be indexed.

#19 Broken Links Remover

Broken links Remover wordpress plugin helps you fix bad and broken links and this applies to both text links (anchor tags) and image links (img tags).It blocks the display of such links on your wordpress post/page, until you fix them. These are not made visible to search engine robots as well, until you correct them.

Broken links are bad for your readers and bad for search engine robots.

Whenever a human visitor or a search engine robot requests a post or a page on your website, this plugin will check the status of all links on that post/page and If any of the links is bad or broken the plugin will log this information  and replaces the link with just the anchor text.

#20 Scribe SEO

Scribe SEO is plugin that works with WordPress to analyze your posts and gives you feedback about them and makes suggestions about how to improve your post from an Search Engine Optimization perspective. If you use the Thesis, the plugin interfaces without any hitch. It also seems to work well with Hybrid and Headway themes. If you are not using any of these themes the plugin will also work fine as long as you have the All in One SEO plugin.

Once you are done writing your post, this plugin does a check to make sure that you have written a well optimized version of your title in the custom title field. It then does a check to see if you have put a meta description. Despite the fact that  the meta description is not a part of the ranking algorithm of most search engines, your meta description is somewhat important because it appears under your page title in the Search Engine Results Pages (SERPs) and putting together a click-enticing meta description is always a good thing. Google uses click tracking data.

And then ultimately, this plugin does a check to see if you have got content for the post. Once all the checks are performed you will see three green arrows like in the screenshot below and then analyze button will “turn on.” Click on this button and the process will start. A really really awesome plugin to get your page with great search engine optimization

Please note that this is a paid plugin service and costs between $17 to $97 per month.
