What is this?
Exclude Industry is an Opteo Improvement for LinkedIn Ads. When a specific industry is consistently generating poor results compared to your campaign group average, Opteo recommends excluding it — stopping your ads from showing to people in that sector and redirecting your budget to better-performing audiences.
Why exclude industries?
LinkedIn lets you target people by the industry their company operates in — Financial Services, Healthcare, Technology, Retail, and hundreds of others. It's one of the most powerful dimensions for B2B campaigns, because the sector a prospect works in often determines how relevant your product is to them.
But broad industry targeting means your budget can end up spread across sectors where your offer doesn't land. An enterprise HR software campaign might convert well from Technology and Financial Services but consistently waste spend on Education or Non-Profit, where decision-making cycles are longer and budgets are tighter.
Identifying which industries are dragging down performance manually requires digging through segment data across multiple campaigns — a time-consuming process that's easy to overlook. Opteo does this automatically, surfacing the industries worth excluding so you can act on them in one click.
How does this Improvement work?
Opteo analyses industry performance across your LinkedIn campaigns using up to 365 days of data — the longest lookback window we use across any platform, which reflects LinkedIn's lower traffic volumes compared to search platforms.
We flag an industry for exclusion when:
Its CPA is more than 2x higher than your campaign group average
Or its ROAS is less than half your campaign group average
It has enough impressions for the data to be statistically reliable (minimum 30, scaling higher for accounts with more conversions — LinkedIn campaigns require a higher impressions threshold than other platforms before Opteo will act)
When those conditions are met, Opteo shows you the performance data for that industry alongside your campaign group average, and lets you exclude it with a single click. The exclusion is applied at the campaign level via the LinkedIn Ads API.
If an industry is still strategically relevant — for example, if you're deliberately building awareness in a sector you're expanding into — you can dismiss the Improvement.
Technical notes
Why this recommendation appeared:
Industry CPA is more than 2x your campaign group average, or ROAS is less than half your campaign group average
The industry has sufficient impressions to meet LinkedIn's higher data confidence threshold
The campaign is active and the industry segment is enabled
Why you might not see this recommendation:
All industries in your campaign perform within acceptable ranges
Insufficient impressions data — LinkedIn campaigns often need more data than other platforms before Opteo can make a confident recommendation
Only one industry is active in the campaign (Opteo won't recommend excluding your only audience segment)
How the analysis works:
Looks back up to 365 days of LinkedIn campaign data
Compares industry performance against the campaign group average (cost, conversions, and conversion value)
Applies a higher minimum impressions bar for LinkedIn than for Google Ads or Microsoft Ads, reflecting LinkedIn's lower traffic volumes
Exclusions are applied at campaign level
