Should You Update All Amazon Bids Every Time?

Why Blanket Bid Changes Usually Fail

Changing every bid at the same time treats all keywords and products as if they have identical performance. In most Amazon accounts, a small share of targets drives most of the sales. The rest may be wasting spend or sitting in a wait-and-see range.

If you reset every bid, you can accidentally lower bids on top performers that were profitable. You can also raise bids on weak targets that need negatives or structural changes instead. A blanket approach hides those differences inside a single upload.

How to Decide Which Bids to Update

Start with performance thresholds that match your campaign goals. For example, look for targets where spend has increased but sales have not, or where ACOS has moved well above the account target over a consistent period. Also flag targets that have become cheaper and are starting to convert, because those may deserve higher bids.

Use your existing Amazon reports to sort by sales, ACOS, clicks, and spend. If you have a dashboard or analytics tool such as the Amazon Ads Dashboard by Todoza, use it to group that data before touching a bulksheet. Then update only the bids that show a clear reason to move.

Common reasons to update a bid include:

• ACOS is consistently above target over the last 14 days
• Sales dropped while clicks and spend stayed flat
• Conversion rate improved sharply after a listing change

When This Matters

This approach matters most when you manage multiple campaigns or marketplaces. A single bulksheet can update hundreds of targets in minutes, which makes it easy to over-edit. If you audit a focused list of changes first, you keep the speed of bulk editing without letting the size of the file dictate the strategy.

It also matters during seasonal shifts, new product launches, or after a major listing change. Those events affect some targets much more than others, making selective updates the safer path.
