This list of free SEO tools will hopefully help you in your daily SEO work. Because Google guidelines are perpetually moving, website optimization cannot be done without any support. These 13 tools and guide will help you gain time and optimize your website rankings.

#1 Google Page Speed Insights

The page speed refers to the time your web browser takes to load a page on a device. A slow loading page can affect how your website is ranking. A low page speed can also increase your bounce rate since your visitors will just go away if it takes too much time to display an information. Google PageSpeed Insights offers insights about your page speed starting from a URL of choice. The PageSpeed score ranges from 0 to 100 points. A score over 85 shows the page is performing well.

We tried this app with Moz website. The app draws a clear visualization of the website performances.  As you can see below, the app splits the results between UX and page speed. For instance Moz mobile website gets 66 points for its UX and 70 points for its page speed which means there is some improvements to do. It is also possible to access further informations to see the details.

From a range of parameters, the app draws a clear insight about your traffic and where it comes from, your audience features, the type of device used and other useful informations.

11# SEO keyword tool by SEOmonitor

SEOmonitor’s free keyword tool allows you to check your keywords’ current ranking on any Google TLD, their search volume, keyword opportunity and difficulty level. The opportunity level of each keyword is calculated against your entire list and for the specific website you are monitoring. Its value varies from 1 to 10, 1 indicating the keywords that are less likely to reach the top in SERP, while 10 represent the ones that require the least effort to maximize the revenue they bring. The difficulty level calculates how much effort you need to put in so you can outrank your competitors and reach the Top 3.

The tool comes in handy whether you want to analyze your website’s performance, a prospect, or any competitor.

    Hi Emma, thanks for the great list.

    I have a suggestion of my own: http://www.urlcheckr.com. It’s kind of shameless promoting a (free) tool I’m working on myself ;-) Would be pretty cool if you could add it to your great list.

    Cheers!

  2. Hi Emma,
    Thanks for the list and great stuff by the way. :-)

    We just made a free online tool that keeps you updated about your pagespeed and it notifies you if it changes.

    So you can have your own PageSpeedAlarm – and soon with history of your pagespeed and suggestion on how to optimize your website.

    Have a look at http://www.PageSpeedAlarm.com – and tell us what you think :-)

    Emma, thanks for compiling such a nice list with necessary tools for SEO boost!

    Google Webmaster Tool, Google Analytics and Google Trends are really must-have tools. Besides, Google Keywod Planner, which is a part of Google AdWords, could be a really great help! (Ha-ha, no I’m not totally crazy about Google Tools, they are really nice, without a doubt!)

    Was pleased to see Copyscape on the list, there was a time, when I used it very often ( long time ago, actually). The main cool features are paid, so for some time I was looking for alternatives and came to Unplag https://unplag.com/.

    Maybe you’ll have a look on it as well? It shows all sources, where are similarities with your blog posts and provides detailed reports.
