    Keyword research


    Every SEO strategy should start with keyword research. Multiple tools can help you find out more about the keywords you’d like to rank for. Moz Pro Keyword Explorer will give you valuable information, like the number of searches, related searches, and competitiveness. Google Trends works well if you’d like to compare two different searches with each other. It will only give your relative numbers to compare, though.

    A marketing and benchmark tool for SEO is SEMRush. It helps to plan and focus your marketing efforts, by providing lots of information on the keywords and advertising strategies that your competitors use. Apart from that it also helps you analyze your backlinks and lets you compare domains.

    Google tools

    Apart from the specific Google tests mentioned above, there are two tools from Google that we can’t skip:

    Google Analytics

    This essential and free tool doesn’t need a long introduction. Most website owners are more or less familiar with Google Analytics. Basic analysis includes the number of users you get on your site and individual pages, what are your landing pages, what route do users follow on your site, what are the bounce and conversion rate of a page and what device do people use when visiting your site. A bit more advanced GA users will be able to set goals, use it for tracking of social media and newsletter traffic and conversion. The possibilities are substantial, which can make it a bit overwhelming for beginners.

    Google Search Console

    While Google Analytics is useful to monitor how users behave on your site, Google Search Console focuses more on your site’s overall health. With this free tool you can check what your site looks like in the search results, amongst others, it checks your structured data implementation, and for errors on your AMP pages. It also gives you insights into how Google indexes your site. In the crawl section, you can obviously find crawl errors (and if you connect this with our Yoast SEO plugin you can fix those right away!) and tests your robots.txt file. And lastly, in the search traffic section, you’ll find interesting info on search analytics, which tells you a lot about how often your site appears in the search results, click through rates and allows you to filter on various devices.

    All-in-one SEO suites

    Want to use comprehensive tools that bundle multiple features mentioned above? Then you might want to check these:


    Ryte is one of the primary tools we use to analyze the on-page SEO of a website. It analyzes if a website is indexable, by checking HTTP status codes, robots.txt file, canonicals, redirects, and pagination. It analyzes your site structure, and your link and URL structure and checks for flaws in your XML sitemap. On top of that, it will give you information on your site’s performance by checking response time and page speed.

    Another complete SEO suite is Searchmetrics. This tool mainly focuses on visibility. It calculates this with a bunch of metrics like how often your page and on which position it appears for a search term in a certain search engine. You can check your visibility changes over time, so you get an impression if your SEO efforts are effective.


    Sistrix is a similar tool as Searchmetrics, it only calculates visibility in a slightly different way. Apart from visibility, both tools will also provide lots of information on on-page SEO factors and backlinks.
