    Ahrefs is one of my personal favorites. Sadly with keyword planner changing it’s usage requirements, I’ve moved onto using Keyword Keg as my main keyword search volume tool.

    You forget to add one of the most powerful keyword research tools out there;

  5. A strong list of free tools, although some of them (like MOZ) really require a paid subscription to get the best out of them, or to carry out analysis of more than a few pages.

    In terms of working on one of Google’s most important metrics for SEO, page speed, the free tool that we find really allows you to drill down & analyse elements of what is slowing a page down is, this allows you to analyse sites using a test location local to your website server, plus use different browsers to ensure consistent results for all users.
