Responsive design is a popular web design strategy used by some of these site builders. This approach reformats the same webpage content to fit different screens. But in terms of SEO (search engine optimization), the search engines only care about whether a site displays suitably on mobile screen sizes. Both Bing and Google have pages where you can enter your URL to see if your site plays on mobile acceptably.
Where they should improve: Some of their templates are modern and slick looking, but most of them look a bit aged. A big limitation of the free plan is that your website will go down, every day, for one hour; if you ask me, this is a no go. It has some of the basic features and add-ons, but there are key elements missing (e.g. a blog or on-site search). When you change to a new template, all the content you had will be lost.
This is a great review post on website builders. I have tried some of them myself but most of them were hard on the budget and too clunky for me to actually use. Weebly and Squarespace did have what I was looking for but decided to abandon them for lack of time. The customer service on most of these is pretty bad (except the top3). I was actually going to do a review on most of these website builders myself but you’ve done a good job here.
Thanks for a great review! My only “con” would be that you didn’t included customer service. But I understand the work it would have involved. I LOVE WIX. I have been with them since they started. But their customer service stinks. I don’t like having to search through a database of questions other users have submitted to find an answer to my problem. They make it hard to find a phone number. Otherwise, besides a few technical beefs I have, it is a great option.
