All of the site builders included here let you put Facebook Like and Twitter Follow buttons on your pages, and some even let you display feeds from the social networks. Some give you help building a Facebook Page and tying it into your site design and updates. Many products offer some sort of SEO tool, but too often this is just a form on which you can enter meta tags. You're mostly left to wrestle with that black magic known as SEO for yourself. It's very important to submit and verify your site to the search engines, unless you don't want anyone to find it!
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.
Absolutely. You have the option to customize your website based on your business needs. You can add site content wherever you’d like in a variety of sections; from multiple site pages, to scrollable sections that you can add to each of those pages, to a gallery of images, menus and price lists, and YouTube or Vimeo videos. Each section in your website is customizable as well, from the name of the page, to your website’s navigation bar. You’ll also have the ability to change text colors, styles and font. It’s important to make a responsive website that is mobile and desktop friendly. With Website Builder you’ll be able to choose tablet and desktop layouts to give your visitors the experience you want them to have.
