What is SEO?
SEO stands for Search Engine Optimization. Search engine optimization (SEO) is the process of increasing the quality and quantity of website traffic by increasing the visibility of a website or a web page to users of a web search engine.
How does it work?
A search engine uses a crawler that gathers information on all the content that can be searched on the web. Then, the search engine builds an index, analyzing the content, images, videos of the page.
Each search engine has its own algorithm that determines the relevance of each page in its index to the search query and organically generates a list of best matched results.

Tips for description:
- Accurately summarize the page content
- Use unique descriptions for each page
In MODX: Depending on when your site was created, the site configurations set up may differ. For older sites, there is an option to set a site description, a global description that applies to all pages within your site under the Extras dropdown in the top menu bar. On all MODX sites, page-specific meta description is available by filling out the Description textarea in the Document tab.

- Using headings. Headings create a hierarchy and structure information for better readability. This also helps search engines crawl and index the webpage. See more information on How to Use Heading Tags to Get More Search Engine Traffic.
