How to Know When to Raise Bids for an Amazon Search Term
← Back to Amazon Search Term Impression Share: When Should You Increase Bids?
Quick answer
Amazon search term bid increases are justified when a keyword or search term has proven conversion strength but is not capturing enough available impressions. Advertisers typically assess impression share, return on ad spend, and conversion rate together. A term that converts well at a low impression share may deserve a higher bid to gain more reach and incremental sales. The decision should still account for search relevance, margin, and the campaign’s overall efficiency.
In practice, a bid increase should not be based on a single metric. When a search term already makes money but shows a smaller slice of available auctions, adding bid pressure can uncover more volume without starting from scratch.
Read the three signals together
Impression share, return on ad spend, and conversion rate are most useful when viewed as a set. A term with high ROAS and strong conversion but a low impression share is often a viable candidate for a higher bid. By contrast, a term with weak conversion may need better ad copy, listing relevance, or negative keyword work before more bid is added.
Start with a reporting view that groups search terms by these metrics. Amazon Ads Dashboard by Todoza consolidates Amazon Ads data, making it easier to spot a term that converts well but is limited by visibility.
When this matters most
This decision matters when a product has enough click and conversion history to make the term meaningful. New or low-traffic terms do not offer the same confidence. It also matters for higher-margin items, where a higher cost per click can remain profitable even if the conversion rate stays flat.
Reviewing terms after a listing change, a pricing update, or a seasonal demand shift can also reveal whether the old bid is still appropriate. A previously limited term may now deserve more exposure.
A practical check before you raise the bid
Before increasing a bid, confirm the search term is still relevant to the product detail page and that the campaign is not limited by budget. Then check placement performance. If a term is strong but mostly appears in lower-placement positions, a bid adjustment may improve placement, but it can also change cost per click quickly.
- Confirm the term’s match type and search intent align with the ASIN.
- Check whether budget caps are hiding additional impression opportunities.
- Review recent conversion data rather than relying on a long historical average alone.
