Link building sounds like an old SEO trick, but it hasn't gone anywhere. It's still one of the clearest signals search engines use to decide who to trust.
Here's the short version. Every time another site links back to yours, Google reads that as a small vote of confidence. Enough of the right votes and your content starts showing up higher for the people searching for it.
The part that catches most people off guard is what this means for AI search. Tools like ChatGPT and Gemini don't crawl the web and count links the way Google does. But they lean heavily on Google and Bing's indexes to figure out who's worth citing. So the sites already building strong backlink profiles are quietly getting an edge in AI answers too, even if that was never the original goal.
If your biotech site hasn't touched link building yet, it's worth a look. It's not just about rankings anymore. It's about whether AI tools even know you exist when someone asks a question in your space.
