Why do posts with links get less reach?
Because a link takes the user off the platform, and platforms are optimised to keep people on it — so outbound links are ranked down, whether or not anyone says so explicitly.
The incentive, stated plainly. A platform's revenue comes from attention it can show advertising against. Time spent on another website is time not spent there. Content that keeps people scrolling is worth more than content that sends them away, and ranking systems trained on engagement will learn that without anyone needing to write a rule.
What the evidence looks like. Creators and publishers have reported for years that link posts receive materially lower reach than native content on the same account. Some platforms have acknowledged deprioritising links; others have not, while producing the same effect. Referral traffic from social platforms to news sites has fallen substantially, which is the same phenomenon measured from the other end.
It is not only deliberate downranking. Link posts genuinely produce less on-platform engagement — people click away instead of commenting — so an engagement-optimised system deprioritises them on measured behaviour alone. The distinction between policy and emergent effect matters less than the outcome.
What creators do about it:
"Link in bio" — the whole convention exists because of this. It is a workaround for platforms that suppress or disallow links in posts.
Putting the link in the first comment, on the theory that the post itself is then ranked as native content. Widely done; effectiveness is debated and changes.
Native content first. Posting the substance on the platform and linking as secondary, which works but gives away the reason for linking at all.
Uploading video natively rather than linking to it elsewhere, which is heavily favoured.
The consequences beyond reach:
Publishers lost control of distribution, having built audiences on platforms that then reduced referrals — a costly lesson repeated across the industry.
The open web is weakened when linking is disincentivised, since links are the connective structure of the web itself.
Screenshots replace links, which strips sourcing and makes verification harder — a direct information-quality cost.
