Campaign Builder

No. This tool builds a bulk file, it does not read one. Everything comes from the form — SKUs, keywords, budgets, bids. When you are done, click Generate and a ready-to-upload .xlsx downloads straight to your computer.

On a new campaign, Amazon's Campaign ID and Ad Group ID columns are not real numbers — they are text labels you invent, reused across every row that belongs to that campaign to link them together. Get one character wrong across a dozen repeated rows and the link breaks silently; Amazon does not warn you until the upload has already happened. This tool generates that token once per campaign and applies it consistently everywhere it is needed, so it is simply not a place a mistake can occur.

Because that is how real launches actually happen — the same budget, bidding strategy and site restriction across a set of campaigns for one product, with only the keyword or match type changing between them. Change what needs to change on the new card; everything else is already right.

The ad group default bid applies to every keyword in the campaign that doesn't have its own. The Bid column beside each keyword overrides it for that one keyword only. Leave a keyword's bid blank and it inherits the default — the placeholder shows you which value it will inherit, so you can see at a glance what blank means. This mirrors how Amazon's bulk format works: a keyword row with an empty Bid column simply falls back to the ad group. Use the override where one keyword is worth noticeably more or less than the rest; leave it blank everywhere else.

Yes. The box beside Add keyword accepts a pasted list, one per line, and turns each line into its own row when you click away. If a line is written keyword | 1.25 the bid is picked up too, so a list copied out of a spreadsheet keeps its bids. Pasting adds to what's already there rather than replacing it.

No keyword list is needed or shown. Once an Auto campaign runs, Amazon automatically generates its own four targeting segments — loose match, close match, substitutes and complements — from your listing itself. You only need the campaign settings, the ad group bid, and the SKU.

Because branded search leaking into non-brand campaigns through broad and phrase match inflates their apparent performance and hides how your non-brand keywords are actually doing — a mistake covered in the campaign structure guide. List your brand name and its common variations once, and every campaign you add that is not itself flagged as a brand campaign gets them as negative phrase matches automatically.

Because Amazon's own upload template does the same checks — bids in two-decimal increments between $0.02 and $1000, daily budgets between $1 and $1,000,000, campaign names of 128 characters or fewer, start dates that are not in the past. A value outside those rules does not always throw a clear error on upload; sometimes it is silently rejected. Catching it here, on the specific field, is faster than discovering it after the file has already been submitted.

Not yet. Sponsored Products is the only ad type this version supports — Sponsored Brands and Display use a materially different set of required fields, including creative and brand assets that a spreadsheet cannot supply. The dropdown is left visible with the other types marked as coming soon so the door isn't a surprise later.

No. Everything you type stays in this browser tab and is used only to assemble the file you download. There is no server, no account, and nothing is sent anywhere until you choose to upload the generated file to Seller Central yourself.
