SEO is a common acronym used among website developers to describe methods used to to improve websites in the eye of search engines, primarily the big G. It stands for search engine optimization and can be as simple as adding those dandy little title tags to your header to as specific as making sure you have your post titles wrapped in h1 tags up as high on the page as you can get them.
I recommend following these tips that I picked up throughout my escapades as a theme developer to make sure your beautiful and elegant-looking WordPress theme is as SEO friendly as it can get, trust me, this could only add more value to it.
This is very simple. When search engines see H1 tags, it is assumed that whatever is inside the tags is an important element on the page. Since post titles are important elements so should they be wrapped in H1 tags.
Simple wrap that in H1 tags and you’re good to go. You may have to make changes to your stylesheet after you make the change so don’t go doing this on a live website without testing it first.
If you have a theme that displays the title and slogan of a website rather than a banner image or something, then this tip applies to you. Be sure to wrap the title of the website in H1 tags and the slogan in H2 tags.
If you have a theme that uses banners instead of displaying the title and slogan of a website, then this tip applies to you. Instead of using regular image tags to show your banner, use H1 tags instead.
These are some of the more important SEO features you can build into your theme to make it more susceptible to being treated well by search engines.
