nofollow
In one sentence
A link attribute telling the engine not to follow the link or count it as an endorsement.
Analogy Mental model
A guide saying he does not know that shop and will not vouch for it. Go and look, on your own judgement.
In practice What you actually do
Apply it to user-contributed links, paid placements and anything you cannot verify. The sponsored and UGC attributes are more precise than a blanket nofollow, and the engine reads all three as hints rather than orders.
Where people get burned Pitfalls
Using it on internal links is a self-inflicted wound: you keep the visitor and throw away the signal. The old idea of sculpting internal equity this way has not worked for years.
