H tags tell the search engine bots which parts of your site are the most important. Are they keywords related to my lead-generating content? Google will show less information in the search results on mobile than on a desktop. Your meta descriptions and your titles will be truncated if you made them too long. Thinks about that when you optimize your posts and pages. SEO (Search Engine Optimisation) is an approach to writing content on the internet that involves using a number of related keywords, titles and pages to help make the website more visible whenever anyone using a search engine enters those keywords.
