Protections tell Opteo which parts of an ad account it should leave alone, even if their recent performance looks weak. They only change which Improvements Opteo suggests. They don't change your ad account, and they don't remove exclusions or negative keywords you already have.
Protected Segments
Protected Segments stop the Segment Exclusions Improvements from suggesting you exclude them.
Open Algorithm Settings from the ad account's Improvements page.
Open Segment Exclusions.
Add the segments you want to protect under Protected Segments.
Click Save Algorithm Settings.
What you can protect depends on the ad platform, for example age, gender, device, network or location, and on LinkedIn Ads company, industry, job title or seniority.
Protected Segments apply to Segment Exclusions. The Location, Demographic and Device Bids & Exclusions sections on Google Ads have their own settings, so to stop those suggesting changes for a segment, adjust that section or switch off that Improvement type. See Choose which Improvement types you see.
Protected Terms (Google Ads)
Protected Terms stop Opteo suggesting n-gram negatives that contain them, like your brand name.
Open Algorithm Settings and open N-Gram Negatives & Bids.
Add terms under Protected Terms (Comma Separated).
Click Save Algorithm Settings.
The first time you open it, Opteo fills the list with the Brand Terms from the ad account's settings. If you change your brand terms later, update Protected Terms too.
A protected term covers any n-gram that contains it. Protecting "acme" also protects "acme tools".
