What is Boost?
Boosted Proposals is an Upwork feature that lets freelancers pay extra Connects to pin their proposal at the top of the client's inbox for a given job. The placement is sold through an auction - freelancers submit a Connect bid alongside their proposal, and the highest bidders get the top slots in the client's view, marked with a Boosted label. Only a few slots are available per job, and the rest of the proposals sit below in the normal Best Match order. Boost does not change the proposal itself. It only changes how prominently the client sees it.
How Boost works on Upwork
When you submit a proposal to a job that supports Boost, Upwork shows you an option to boost it. You enter a bid in Connects on top of the standard Connect cost of applying. Upwork runs a sealed auction among all freelancers who choose to boost that same job. The top bids win the boosted slots at the top of the client's proposal list, and the freelancer is charged the second-highest bid amount, not their own bid - the same way many ad auctions work.
A few mechanics worth knowing:
- Limited slots. Only a small number of boosted positions are available per job. Most freelancers in the list are not boosted.
- You pay even if the client ignores you. Like regular Connects, Boost Connects are spent the moment the auction settles. No reply, no refund.
- The proposal content is unchanged. Boost only buys placement. A weak cover letter pinned to the top is still a weak cover letter - it just gets read first before being dismissed.
- Visible label. Clients see a Boosted badge on your proposal, so they know you paid for the slot. Some clients value the signal, others ignore it.
Boost is most useful on jobs that are a strong fit, where you are confident the cover letter will hold up to scrutiny, and where the applicant count is high enough that being in the top 50 proposals is a real risk. On a low-traffic job, regular submission is usually enough.
Example
A senior backend engineer sees a job posted by a well-reviewed client for a Stripe integration project. The job already has dozens of applicants within an hour, and his standard proposal would land somewhere in the middle of the list. He chooses to boost the proposal with a moderate Connect bid. He wins one of the top slots, the client sees his proposal first, opens it, and replies for a call. On a different job the same day, with a brand-new client and only a handful of applicants, he submits a regular proposal because Boost would just be paying for a slot he could earn for free.
Why Boost matters for freelancers
Boost matters because Upwork inboxes get crowded fast on good jobs. A strong cover letter that lands at position 80 in the list often never gets opened, no matter how well written it is. Buying the top slot on the right job can be the difference between a reply and silence.
It is also a budget question. Boost Connects stack on top of regular Connect costs, and they are not refunded if the client ignores you. Spending them on bad-fit jobs is the fastest way to burn through a monthly allowance with nothing to show. The freelancers who get value from Boost are picky about when they use it - high-fit jobs, credible clients, crowded applicant pools.

Boost vs Upwex Auto-Bidding
This is the most common confusion in the Upwex glossary, so it matters to be exact.
- Boost is Upwork's paid placement product. It pins a proposal you already wrote to the top of the client's list, in exchange for extra Connects. It is a one-job, pay-per-slot auction.
- Upwex Auto-Bidding is Upwex's scanning and submission tool. It watches new Upwork jobs that match the filters you set, scores them, generates a cover letter, and submits the proposal for you. It does not buy placement. It does not interact with Upwork's Boost auction.
The two are independent. You can boost a proposal that Auto-Bidding submitted, or send a boosted proposal manually, or do neither. Boost is about where your proposal sits in the client's list. Auto-Bidding is about which jobs get a proposal in the first place.
Frequently asked
How much does it cost to boost a proposal?
It varies by job and by how many other freelancers are bidding on the same boosted slots. You set the Connect amount you are willing to spend, and Upwork charges based on the second-highest winning bid in the auction. There is no fixed price.
Does Boost guarantee the client will reply?
No. Boost only pins your proposal at the top of the list. The client still has to read it, like the cover letter, and decide to reply. A weak proposal at the top still loses to a strong proposal further down.
Can I boost a proposal after I send it?
No. Boost has to be selected when you submit the proposal. You cannot go back and boost a proposal that is already in the client's inbox.
Is Upwex Auto-Bidding the same as Boost?
No, they are different products. Boost is Upwork's paid placement auction for a single proposal. Auto-Bidding is Upwex's tool that scans new jobs and submits proposals for you. They can be used together, but neither one replaces the other.
When is Boost worth the extra Connects?
Generally on high-fit jobs with a credible client and a crowded applicant pool, where being in the top 5 proposals meaningfully changes whether you get read. On low-traffic jobs or weak-fit ones, the extra Connects are usually better saved.
