SEO Tools do not have to be expensive. For smaller websites, tools like Ryte or Seobility extensive OnPage analyses are made free of charge. With the gained information and data you get a good overview of the current state of a website with all its problems and potentials. For large websites with more than 100 subpages or even websites that have been on the Internet for many years and have many backlinks, free SEO Tools can reach their limits. Because these are mostly limited in functionality and provide only limited information, such as the number of maximum crawlable websites or data on backlinks. Free SEO Tools like Google Analytics, Google Search Console or Bing Webmaster Tools can help here and provide a variety of useful reports and functions. Every Webmaster should use these tools for their websites and projects.
