The search for the best Firefox Add-ons for SEO

The browser Mozilla Firefox is home to many useful SEO plugins and toolbars. I found 7 of the best Firefox addons that can make a difference to our daily SEO activities. The extensions that are recommended here are updated by the respective developer no later than the last quarter of 2015. The Firefox extensions are tested on Firefox 44.0.2 with no conflicts, but results may differ for you.

1. Ahrefs SEO Toolbar

Start to get insights on key SEO metrics for individual web pages, domains and even SERPs (see below image). Using the SEO toolbar from Ahref, it makes our keyword or SEO research much more effective. You get overview information such as the number of backlinks, number of referring domains, social media metrics for Facebook, Google+ & LinkedIn, and more.

However, free users do not get all the features. So for example, if you want to know where the backlinks are coming from, then either you subscribe to their monthly plans, or take advantage of their trial and use it while it lasts. firefox addons for seo

2. SeoQuake

SeoQuake is designed for webmasters who are constantly working on SEO (Search Engine Optimization) and SMO (Social Media Optimization). Similar to the Ahref addon, SeoQuake provides SEO metrics for the web page you are on, domains, and search engine results.

SeoQuake goes a step further by providing SEO parameters (within search results) for you to sort according to your preferences. Below is a screenshot captured during a Google search. SeoQuake provides default parameters, but you can customize it to what you want. Common parameters include but not limited to.

  • PageRank
  • Number of indexed pages
  • Number of links pointed to the domain/page
  • Similar parameters available for Yahoo, MNS, Yandex, Rambler, Baidu

What I like about SeoQuake is the integration it had with other 3rd party service providers such as Semrush, Wordstream, DomainTools, Alexa, etc. Because of these integrations, we are able to get more information like Whois records, domain age, keyword density and more. And if you have paid subscriptions to some of these 3rd party services, it really makes SEO activities more comfortable and effective.

 3. SEO Toolbar by Moz

In terms of overview SEO metrics provided by Moz, you don’t get as much as Ahref or SeoQuake. Metrics are shown on URL level, and search engine results. If you intend to use this as a free addon, probably the only useful feature is Open Site Explorer (OSE) which gives you key SEO metrics on any URL/domain. Other useful in-built tools are Whois records, page analysis (elements & attributes) and link data. What I like about OSE is that you can export data and links onto a CSV file. Again, there is a limitation on the amount of data we can get free. We can’t blame them since it’s just a way for Moz to get us to subscribe to their services if we find it useful. Anyway, limited or not, it is a good place to start with, especially for beginners.

Another piece of information that you can obtain with the SEO toolbar, is the MozRank (link popularity score) and MozTrust (trust score). If you are curious on how the scores are calculated or what it represents, you can read here and here.

4. SimilarWeb – Website Traffic Sources and Ranking

This is an awesome Firefox addon to have. It’s perfect to find out how are you doing against your competitors, identifying your strengths and weakness, and overview of your performance in different areas. Use the plugin to find out how you or your competitor are doing on:

  • rank by global, country and category,
  • traffic overview (visits, time on site, page views on average, bounce rate),
  • traffic by countries,
  • traffic sources,
  • referrals,
  • top referring sites,
  • top destination sites,
  • searches (organic and paid),
  • social traffic, and more!

One drawback is that you are not able to find information on new websites because of lack of data. However, what I like about SimilarWeb is that you can compare any websites to know their strengths and weakness, and plan your marketing strategies accordingly. Being able to export the reports out in PDF sweetens the deal.

5. Web of Trust, WOT: Website Reputation Rating

Once you install Web of Trust, your search results are going to look slightly different. The addon shows you the reputation each website when you conduct searches. The reputation ratings are displayed as traffic light-style icons at the end of each web page title.  It’s color coded as green, yellow or red, representing safe to visit, be cautious, and danger respectively.

The free Firefox add-on doesn’t provide lots of fanciful features, but it is handy to flag out any domains/URLs that can be detrimental should you link to them.

Trusted by millions of users, Web Of Trust (WOT) has also been featured in the New York Times, CNET, PC World, and many other media.

6. SEO Toolbar by Trellian

The SEO Toolbar shows PageRank, Alexa, Popularity Index, Compete & SEMRush rank for any website you visit. If you are to compare this toolbar with Ahref or SeoQuake, it doesn’t show you as much key SEO metrics. However the toolbar is useful as it groups different SEO activities under different folder on the toolbar. This gives you some kind of reminders and structure when you are doing research or marketing. For example:

  • PPC Engines
  • SEO tools
  • Keyword research
  • DNS tools
  • Forums

Personally, I think this plugin is more suitable for starters, and it can be made better if users are allowed to customize the toolbar.

7. RDS Bar

What I like about the this add-on is the amount of SEO metrics that are available in a glance (on search results). Below is a screen capture done on one of the Google search results.

If you are into link building, you will be happy to know that RDS connects with Majestic SEO to provide scores on Trust Flow (TF) and Citation Flow. There are many other metrics available, and you can even have the freedom to customize whatever metrics/parameters you the bar to display. The SEO toolbar is well designed with the users in mind.

I leave it to you to explore them. Have fun!
