Search engine optimization is the work of making your pages easy to find, crawl, understand and choose in organic search results. This hub covers the parts of SEO that practitioners deal with every week: technical foundations such as crawling, indexing, site speed and structured data; keyword research and search intent; content that answers the query better than the pages already ranking; internal linking; and earning links without buying them. Guides here focus on Google, because it sends most organic search traffic for most sites, but the principles apply to Bing and other engines as well. Where Google publishes official documentation, articles link to it so you can check the source yourself. SEO also overlaps more and more with GEO, the practice of getting cited in AI answers, so you will find links between the two hubs where the work is the same. Start with the guides below, or filter by subject.
Google has no official meta description character limit: it truncates snippets to fit the device width, so the real limit is measured in pixels. In practice, write around 120 to 160 characters and put the key message in the first 120.
