When it comes to your website’s SEO, search engines like Google don’t differentiate between one website builder or any other content management system (CMS) your site is built on. The key ingredients for great SEO consist of lots of fresh quality content, a dash of backlinks, and providing the best possible experience for your visitors. Also, the tools that Wix provides has improved a lot and are now much more powerful, that 80% of users have seen improvements in their ranking. So I don’t think you will face difficulty in optimizing Wix website.
