Boosted Proposals is Upwork's paid placement for proposals: a freelancer or agency bids extra Connects to have a proposal shown in the top positions of the client's list, with the slots going to the highest bids.
When submitting a proposal, Upwork offers the option to boost it by naming a number of Connects above the ordinary cost. The boosted slots at the top of the client's proposal list go to the highest bids at the time the client looks, in an auction that runs while the job is open. Upwork's Help Center sets out when the bid is charged and when it is returned; broadly, a bid that does not win a slot is not spent, and the rules are set by Upwork and may change. The client sees the boosted proposals first and marked as such.
The product exists because clients rarely read past the first page of proposals on a popular job, and the top of the list is worth paying for. It is one of several advertising products Upwork has added since 2022, alongside the availability badge, and together they are a growing part of Upwork's revenue and of its take rate.
Boosting changes position, not quality. A boosted proposal with a weak cover letter or a bid far from the budget is still rejected, only faster, and a client who filters by badge or location may never see the list order at all. Upwork publishes no figures on how much boosting raises hire rates, so any claim about its return is the freelancer's own experience, not a platform statistic.
