Technical SEO tools you probably haven’t heard of
Technical SEO is defined by configurations that can be implemented to the website and server (website’s code and server configuration). With technical SEO, you can help search engines access, crawl, interpret and index your website without any problems. As such, technical SEO doesn’t include analytics, keyword research, backlink profile development or social media strategies. By improving your website’s technical SEO, you can earn higher rankings in search results, drive more traffic to your website, and increase your conversion rates. There are literally hundreds of free technical SEO tools out there, so in this article I want to focus on only the best and most useful ones. You don’t have to be a developer to use them as they are all fairly user-friendly and can save you time having to bother a developer as well.
