Three different pages, three different jobs — and a lot of small business sites quietly use the same generic copy across all of them, because nobody wrote them with a specific reader’s entry point in mind.
A home page has to orient someone who doesn’t yet know exactly what they need — broad enough to cover what the business does, structured so a visitor can self-sort into the right next step. A landing page is the opposite: built for one specific traffic source and one specific promise, matching exactly what got that particular reader to click in the first place. Send someone who clicked a very specific ad to a general home page instead of a landing page built around that exact offer, and the whole reason they clicked gets lost the moment they arrive. A sales page is different again — built to carry a complete argument for one specific decision, for a reader who’s already past the orienting stage and needs the case made in full, not just an overview.
Treating all three as interchangeable — one page, reused everywhere, with the headline swapped — is one of the more common ways a business quietly loses the specific advantage each entry point actually offers. Paid traffic in particular pays for this mistake directly: the ad earns a very specific click, and a generic page then fails to honour the specific promise that earned it.
None of this means every business needs all three built out immediately. It means knowing which one a given page actually is, and writing it for that job specifically, rather than one all-purpose page trying to do all three at once.

FAQ
Can one page realistically do the job of more than one of these? For a very small site, sometimes — a combined home-and-sales page can work for a single-offer business. The trade-off is that it has to do double duty for two different kinds of reader at once, which usually means it does neither job as sharply as a dedicated page would.
