If you designed your law firm website on Wix, you’ve got a problem. While your website is still there, Google has probably deindexed it. That means nobody will be able to find it on Google — which effectively means nobody will be able to find it.
[W]hen one Wix site starts having problems, all Wix sites are likely to suffer a similar fate.
Google is working to reindex Wix sites that aren’t causing problems, but this does illustrate a problem with big website networks like Wix. Even if it is a bit more difficult, you might be better off installing WordPress and setting up your website yourself, instead of trusting it to a big network.
