Well-established tech sites are suddenly super-interested in crypto and gambling. They make brand-new pages that rank top three in months for hard keywords, outpacing sites that have ranked consistently for those keywords for years.
How does a general tech site wind up ranking in the top five for gambling-related search terms all over the world? Tech sites ranking for gambling keywords.
The answer is called parasite SEO. If you’re an SEO, skip this part, you know it. But for everyone else, Google changed the way it ranks content recently. Domain authority, which is basically how much Google respects your domain, counts for a lot more now. Older sites that have been building a reputation for years have higher domain authority.
Parasite SEO is when you use a site with high domain authority to host content that has nothing to do with the site. Like writing pet insurance content on a business site. You’re parasitising on the domain authority to get the content to rank. (There’s a good general guide to parasite SEO here.)
Steve says it as well as anyone. Parasite SEO just cancels the rules of good SEO. (https://www.seroundtable.com/google-parasite-seo-steps-36526.html)
