If entries relevant to the technologies which concern us use different terminology, it can be an interesting avenue to explore.
Wikipedia can have a role to play in SEO when we struggle to come up with terms that people may be looking for. Most entries relevant to the technology and market sectors which concern us will have been written by other experts, and if they use different terminology, that can be an interesting avenue to explore.
There’s also an interesting and little-known page view tool for the site which can be revealing when we’re investigating the interest in a topic.
While adding links to our sites on Wikipedia pages has no SEO benefit, it can provide some good traffic. However, we should only ever add links if they’re to facts and data where our sites are genuinely the primary source on the internet. Spurious commercial links not only look tacky, they get removed pretty quickly.
