This article explains some steps you can take to improve the search engine optimization on your site, as well as accessibility, all at the same time.
Headings, landmarks, and Alt Tags
When designing a site, many developers choose to add links to skip to navigation or content. Adding aria landmarks is a way to do this without impacting the appearance of your site. Search engines use this information to determine what part of your site is most important to search, and screen reader users can easily move between these landmarks.
Heading tags are also a powerful way to divide up content. Using tags for such things as article titles and major sections make the page more understandable for readers, easier to navigate for screen reader users, and indicates the relevance of each section to search engines. Alt tags are a way of labeling images without the text of that label being visible to viewers. Here’s an example:
<img src="myfile.jpg" alt="picture of a happy search engine"> The alt tag is readable by search engines, unlike pictures, and is readable by screen readers. This is especially useful for graphical links, because search engines use this information to better understand why the link is there, and what it links to.

Using the label to identify text fields and other elements is an excellent way to have a clear form layout, let search engines know more about your page, and keep screen reader users informed about what information is required. CAPTCHAs are commonly used to prevent spam from appearing. There are much better ways to accomplish this goal, including solving a simple math problem.
