I'm an SEO who specializes in Wix website optimization and nothing else. I've optimized over 150 Wixsites and have noticed the same mistakes being made again and again. So much so that every time I send an SEO report to a new client, I'm practically repeating myself. I'd like to help you avoid those mistakes.
Most site owners I've come across don't have time to sit down and learn the intricacies of SEO. Many originally believed that once their site has been made, it would simply show up in search results whenever people searched for the products or services they had to offer.
Because of that, pretty much all every Wix website owner I've worked with aimed to build the most beautiful site possible, entirely unaware that every additional slideshow, gallery, animation, video background etc they added was slowing their site down and detracting from their chances of being found online. As a result, I've often began by telling clients that they own the most beautiful website that would never be found.
Some Wix website owners created their site through the Wix ADI automatic set-up process, whereby clicking on a preferred template and entering a few basic details allows your new site to appear as if by magic. They're never told that Wixsites created using the Wix ADI feature are hopelessly out of touch with both SEO best practice and Google guidelines and are, at most, only useful for advertising campaigns. They cannot be optimized and will never bring organic traffic.
Other Wix website owners chose to go it alone and created their own website using one of the over 100 Wix website templates available. Each one does look "stunning", just like Wix promised. Unfortunately, site owners who don't know anything about SEO will just assume that each template is equally search-friendly and choose the one that best catches their eye. Because of that, they are taken down a path that leads to a beautiful but bloated JavaScript heavy site, stuffed full of unnecessary extras and too poorly laid out for Google spiders to efficiently crawl or understand.
Finally, the third type of site owner I see are the unluckiest. They choose a site designer to create their website for them and burn through a significant advertising budget as a result. Because site designers are not SEOs, the site owner not only ends up with site that is poorly optimized, they are also left mystified and frustrated as to why they aren't getting organic traffic.
