The first step? Putting Weebly's many simple and powerful SEO features to use.
Page Titles & Descriptions
Page titles and descriptions appear directly in search results when someone finds your site on a search engine, giving you a great opportunity to influence searchers to visit your site. These also provide you with the ability to use search phrases you'd like to rank for. For example, let’s say you own a business in Oakland called Rockridge Bakery that has been around since 1972.
Page title: About Rockridge Bakery: Serving Oakland since 1972
Page description: Rockridge Bakery is a family-owned bakery and cafe that has been part of the North Oakland community since 1972.
The option to add Titles and Descriptions can be found in the same place as the permalinks discussed next.
Every page on your site has a name that you provide (separate from the title noted above), and this name is used by default to both generate your navigation and to create links for each individual page. You'll generally want to keep these names short and to the point for navigation purposes: Contact, About, Store, etc. And when you do this it also means that you end up with very short links: mysite.com/about, mysite.com/contact, etc.
The thing about using these short names for your links is that you're missing a valuable opportunity to use those links to highlight how you'd want them to be found via a search, since search engines take those names into consideration when ranking your site.
So for your About page, you could be more descriptive for your permalink (about-the-rockridge-bakery-team).
And don't go overboard. Still try to keep your permalinks to five or six words.
The Header & Footer Code
If you're moving a site from another host to Weebly, ideally you don't want to lose all the search engine history and optimization you gained from your time with that site. And, thankfully, there's a way to redirect both traffic and search engines from your old pages to your new ones within Weebly using the 301 Redirects feature.
This option is found under Settings > SEO in the editor, at the very bottom of that page. All you need do here is enter the page permalink from the old site and select which new page that should point to in the new one. Then Save.
Once you get these basic Search Engine Optimizations in place, you'll be well on your way to seeing your site ranking much higher in search results. Next up, read a more advanced SEO guide like Are the Right People Searching for You? or How to Create a Perfectly Optimized Page.
