Search engine optimization (SEO) is the process of improving a website's visibility and ranking in search engines like Google, Bing, and Yahoo. The goal of SEO is to help users find a website and decide if they want to visit it. Here are some things to know about SEO: How it works Search engines use a three-step process to rank websites: crawling, indexing, and ranking. Search engines send out web crawlers to find new pages and record information about them. If a search engine deems a page worthy, it's added to its index and ranked. How to improve SEO There are many ways to improve a website's SEO, including: On-page optimization: Use relevant keywords in titles, meta descriptions, and headlines. For example, if you're writing a blog post about making ice cream, you might include the keyword "homemade ice cream" in all of these places. Off-page optimization: Improve link popularity. Local SEO: Create a Google My Business account and optimize it for local searches.
