Did you make the mistake of using Squarespace, Shopify or something else locks you into their servers to build your site? Do you want to own your data?
Owning your own data is important, especially if you are selling stuff through your website. You do not want your customer and order lists stuck on a platform that could disappear if the company goes out of business or decides they do not like your site. Having backup copies of your site on your own computer (or somewhere you can get it) is important for restoring your website quickly if something happens.
These hosting companies also have very sloppy and bloated code which can cause site to not work right or be really slow. If you look at the source code for the pages sent to your browser by these companies, you can see lots of of stuff where it does not belong and sometimes it lacks the actual content in a format easy for search engines to read.
We can get most of your data off of these restrictive systems and put it onto a standard platform, like WordPress, that you can take to any standard hosting company. Both types of sites can be backed-up and moved to a different host. Site transfers from hosting companies that use proprietary builders are treated like recoveries, so we charge $105/hour right now.
