Today let’s take a look at the SEOpen Firefox extension. This extension can be downloaded from https://addons.mozilla.org/firefox/570/. This extension adds a toolbar on Firefox, from where you can view SEO-related information from Google, Yahoo!, MSN, Alexa, and several other resources on the page you are at.
Below is a screenshot of what the extension looks like when clicking on “Other Tools”.
Below is the score for each category:
Ease of installation: 5
Ease of use: 3
Amount of time for the information to appear: 4
Usefulness of information presented: 3
Amount of real estate taken up: 3
Ease of installation: Installation was quick and problem free.
Ease of use: There was a problem with one of the links (page size, which returned a 404).
Amount of time for the information to appear: It takes two clicks to get to the desired information. Once the metrics are selected, though, information does appear quickly.
Usefulness of information presented: Good for getting info on the page you are on. A minus is that it shows backlinks info from Google, and it is known that the link: command in Google returns incorrect numbers.
Amount of real estate taken up: An additional toolbar appears on the browser.
Documentation: Adequate documentation is available at http://seopen.com/firefox-extension/index.php.
Make sure all links are valid.
Take out information that is known to be highly inaccurate (such as backlinks from Google).
