N-gram analysis is used by Google Ads marketers to identify individual words, pairs, or trios of words within the search term report that are performing particularly well, or particularly poorly. For a detailed overview of n-gram analysis and how it can help enhance Google Ads performance, check out the help article here.

The Reduce N-Gram Bid Improvement in Opteo is designed to reduce wasted spend by identifying low-performing keyword n-grams and recommending bid reductions where appropriate.

If Opteo finds a word in the search term report that has 0 conversions, costs three times more than the average or target CPA, and you have manual CPC keywords that contain the word, Opteo will recommend that you reduce its bid.

Opteo calculates the appropriate bid adjustment to bring performance back in line with the average for the campaign group, or your target CPA. Opteo will never recommend reducing a bid to below the first page bid estimate. Opteo will also never recommend lowering a bid by less than 3% because this will make little impact

To help you decide whether you'd like to push this Improvement live to Google Ads, Opteo will show you exactly which keywords, and in which campaigns, the bid reduction will apply to.

Opteo will only ever reduce bids on keywords with 0 conversions. If any keywords containing the n-gram do have conversions, Opteo will filter those out when applying the bid adjustment.

Note: If Opteo finds a poorly performing n-gram that you aren't directly targeting in your keyword list, it will generate an Add N-Gram Negative Improvement instead.
