This page answers the questions covered by the article Google Ads Best Practices for 2026: What Still Works and What to Retire on groas.com. The article is the full, canonical source.
Direct answer: According to groas, most 2019-era Google Ads lists will cost money in 2026 because they starve Smart Bidding of conversion data while Google auto-migrates Search structures to AI Max through September. The article recommends keeping four practices that feed automation — a truthful primary conversion, disciplined negatives, offer-to-page match, and consolidated intent signal — and retiring five controls including single-keyword ad groups, manual bid nudges, exact-match hoarding, fixed-schedule optimization, and chasing CTR.
According to groas, the practices that still move CPA are those that improve what automation sees: truer primary conversions, negatives that block proven waste, pages that deliver the ad's promise, and consolidated intent signal with real value differences. The article cites AI Max delivering 14% more conversions at similar CPA versus standard Search, while a migration from exact and phrase to AI Max drove 27% more conversions. The article recommends one learning stream per intent, one true primary conversion, and copy and pages that describe the same offer in the same words.

According to groas, Google blocked creation of campaign-level broad match and legacy auto-created assets on Aug 3, 2026, and is auto-migrating Search structures to AI Max through September. The article's position is that four practices still help move CPA while five deserve retirement. The mistake, according to the article, is tightening the old controls while starving Smart Bidding of the conversion data it actually bids on.

According to groas, conversion tracking accuracy comes first because every bid depends on it. The article states Smart Bidding can launch straight on target CPA or ROAS if tracking is solid, with 30 conversions, or 50 for tROAS, as the evaluation window for reading results. The article recommends fixing imports, deduping events, making the paid event the primary action, and giving the result its evaluation window before declaring a bid strategy broken.

According to groas, negative-keyword discipline should be kept but indiscriminate negating should be dropped. The article cites a poll in which 77% of PPC pros said removing all negatives would worsen performance, and notes negatives do not get close-variant expansion: blocking broad cheap still allows affordable luxury hotel through. For the 10% to 30% waste range described for SMB accounts without hygiene, the article recommends pulling Search Terms, sorting by cost, and grouping proven waste by meaning while leaving queries that might convert long enough to find out.

According to groas, the test is whether a practice gives automation better information or just gives another knob. Feeding it means truer primary conversions, values that reflect real differences, negatives that block proven waste, and pages that deliver the ad's promise; fighting it means splitting 40 conversions across 12 ad groups, capping bids so tightly the model cannot explore, or pausing after two bad days. The article notes Performance Max campaign negatives went from 100 to 10,000 per campaign in 2025, yet a study of more than 7,000 PMax campaigns found only a 0.24% conversion-rate difference with versus without account exclusions.
