I’m not talking about your common SEO plugin for WordPress. I’ve already covered those in a previous post. I’m talking specifically about plugins that are popular in the WordPress community that unintentionally boost SEO. All 10 plugins that I mention here have 1 thing in common. They accomplish a primary objective, while benefiting SEO as a secondary objective.

1. WordPress Mobile Pack = A Mobile Version Of Your Site/Blog
While more and more searchers are using mobile devices, Google is having to constantly improve not only search results pages for normal browsers but for Mobile browsers as well. What this means is that if you don’t have a mobile version of your site/blog, you could potentially be missing out on a large percentage of visitors through mobile browsers. Get a mobile version of your site and get higher ranked for organic mobile search results.
2. WP Super Cache = Increase Site and Page Speed
Now that Google search results are now “instant” thanks to their new implementation of Google Instant, page load speed is now more important than ever. WordPress blogs because they are database driven, can get bogged down especially if you have decent traffic. This plugin will cache your pages as static .html files to increase page load speed like crazy!
3. ShareDaddy = Promoting Content Through Social Media
There are many plugins as you probably already know that give added social functionality to your blog. Whichever one you choose to use is entirely up to you and your personal preferences. Now that Google is confirming that Facebook and Twitter influence SEO, it’s now more important than ever to get your visitors to “like” and “retweet” your content.
4. Secure WordPress = Preventing Your Site From Being Hacked
Nothing will kill your hard-earned SEO efforts faster than getting hacked!!! Trust me when I say it’s one of the most painful experiences in life. All that hard work could disappear in seconds. Take some action to better secure your WordPress site/blog and prevent this sort of disaster from happening.
5. Askimet = Keeping Out The Spam
Another thing you don’t want is a bunch of spammers “spamming” your comment threads with links to “viagra” and “pharmacy” and junk like that. Askimet will help you by filtering out all of the spam so you don’t lose any potential link weight to these evil black-hatters.
6. Subscribe to Comments = More User-Generated Content
The more user-generated content the better when it comes to SEO. Which is why this plugin is so important. It allows commenters to subscribe to a comment thread so they can receive an email when someone replies to their comment(s). This increases the conversations on your blog like you wouldn’t believe!
7. Yet Another Related Posts Plugin = Creating Engagement & Lowering Bounce %
So you get a new visitor to come across your site via a Google search. Now what? Can you keep that visitor engaged? Can you get that visitor to click to another page and read more of your content? Data shows that if you can decrease your bounce rate on a given page you can improve your rankings for that page. One way to accomplish this is by displaying relevant content to your visitors that’s related to the content they are reading at that moment.
8. Popular Posts = Creating Engagement & Lowering Bounce %
This plugin will help you accomplish nearly the same thing as the previous mentioned Related Posts plugin. Showing off your most popular content is another way of keeping a new visitor on your site and reading more of your content and thus… lowering your bounce rate.
9. Affiliate Plugin = Generating Thousands of Back Links
Magic Affiliate & WordPress Affiliate Platform
One crafty way to generate a ton of back-links for SEO is by starting up an Affiliate Program for your products and/or services that affiliates can sign up for and promote. While typically these URL’s are unique for each affiliate, the SEO benefit is still there because of the promotion that is taking place when an affiliate sends traffic your way.
Note: in all my research I could not find an open-source affiliate plugin for WordPress. Both of these mentioned cost $
10. Google Analytics for WordPress = Tracking + Being Google Friendly
I have a theory (and i’m not the only one) that utilizing the Google “family” of products helps improve transparency between you and Google and thus improves SEO rankings. Products such as Adwords, Website Optimizer, and yes Google Analytics. This is in my opinion the very best Google Analytics plugin for WordPress created by none other than Yoast.
So what are you waiting for? Get these plugins installed and track the results that follow. You will be pleased with what you see! And be sure to read my Free SEO Report called the SEO BlackBook to learn some other SEO tricks as well.

WP Super Cache is good and we recommended it to high traffic blogs when I was a linux admin for Hostgator.com, but I found that if you use plugins that load dynamic sidebars based on searches, traffic or content on the fly, this plugin does not work so well as the pages are cached and not really dynamic.
With most hosts and specially Hostgator, the number of queries to the search engine is what will get you, not the loading of html, php or images. The plugin I suggest is DB Cache Reloaded, which caches the actual database queries, instead of all the content.

I agree. A site that gets hacked, sends out spam or links to dodgy websites, then gets indexed by Google isn’t going to have a nice time! Nice idea; never thought of it that way!
