Installing Manually

  1. Upload the seo-booster folder to the /wp-content/plugins/ directory
  2. Activate the SEO Booster plugin through the ‘Plugins’ menu in WordPress
Is this a replacement for WordPress SEO by Yoast or the All in One SEO Pack by Michael Torbert?

No! These plugins are great and I use and recommend using those to everyone that works with WordPress and who are serious about optimizing their SEO.

This plugin does not do a single thing they do, SEO Booster does a lot of things that they dont do.

SEO Booster was born in 2008 from another need. The original version was premium and was focused on gathering keyword data and rankings from Google. Back then a lot more information was given by Google about what keywords visitors used to find your website, but often even the actual position on the search result page – SERP for short.

It has been years since Google stopped doing that, and SEO Booster evolved to monitoring vistors from 400+ different sources – giving much more details about how your content is found by people searching online.

Most websites will get over 90% of their search engine traffic from Google, but almost no keyword data.

By listening to many other sources you will get a much better picture of your keyword traffic.

You can use the keywords module to dive in to the keyword data – fast using AJAX so you can navigate without waiting for page to reload.

Over the years SEO Booster grew up and went through many different variations and new features.


Not only does SEO Booster listen to visitors from search engines, every time a visitor comes via a link from another website, this is recorded also. The amount of visitors, first visit and so on.

The PRO version actually visits the pages and verifies if the link exists and if so, which anchor text is used, is it an image, is it nofollowed and so on.

To help discover new backlinks quicker, there is also an RSS feed you can subscribe to listing new backlinks as the come in.

404 Errors

Every time a visitor follows a link to your website that does not exist, a 404 Error Page Not Found is displayed. Having any 404 errors on your website gives a bad experience for your visitors and Google is not too happy about those either.

Some times you need to let the page be forgotten by letting it give a 404 error, other times you need to redirect to somewhere else.

This module gives you the list of most visited 404 errors and which you should pay most attention to.

Forgotten Pages

Google changes their algorithm regularly, and your competitors are not sitting idly by. By monitoring visitors from search engines, SEO Booster can tell you which pages on your website is no longer getting any traffic.

These pages used to get traffic from search engines, but are now no longer visited.

Weekly Email Reports

Get a weekly email report with a summary of new keywords and most popular pages.

Dynamic Tagging

Dynamic tagging links your posts by creating terms and automatically tagging related posts or pages.

  • Works with any taxonomy
    Choose which taxonomy to use – Taxonomies are created based on different criteria, such as minimum and maximum length of the keyword.

  • Works with Custom Post Types – CPT
    You can choose which custom post types to link with the taxonomy if it is not already associated.


  • Use any taxonomy.
  • Assign all post types to taxonomy.
  • Set minimum and maximum length of term to create terms automatically.
  • Set a maximum of terms/tags per post.
Logging Details
  • Turn on detailed logging to get more information shown in the log. On heavily visited sites this can add a lot of details.
  • Turn on debugging for helpful information when trying to find a bug.

  • Remember, you should noindex all terms and taxonomies in general. Unless you know what your are doing SEO-wise, you may hurt your rankings. User this to help you interlink and group your content. *

or any Custom Post Type (works with other plugins and themes)

Crawled pages – PRO only

The PRO version also comes with:

This module track visits by search engine robots and crawlers, helping you identify which pages are crawled, and which are not regularly visited.

  • Crawled pages module – Every visit by a search robot crawler is recorded and this will give you a chance to see which pages are most frequently visited, but also which could need some help getting more attention.
Export – PRO only

In the Pro version you can also export backlinks and keywords to .csv
