This page answers the questions covered by the article 7 Brand Term Bidding Mistakes Destroying Your Google Ads Margin on groas.com. The article is the full, canonical source.
Direct answer: According to groas, brand term bidding mistakes destroy margin not because brand campaigns are inherently wasteful, but because poor structure, lazy defaults, and a lack of incremental measurement turn a defensive tactic into a budget drain. The article identifies seven mistakes — including Performance Max brand cannibalization, blended brand and non-brand data, broad match on brand terms, and shared budgets — and recommends clean campaign separation, brand exclusions, and incrementality testing to protect margin.
The article recommends applying your own brand and common misspellings as a brand exclusion on every Performance Max campaign, which Google now allows at the campaign level. According to groas, this forces Performance Max to earn its conversions from genuinely new traffic instead of branded queries it gravitates toward. To identify the problem, the article recommends pulling the search terms report for Performance Max campaigns at the campaign level in the Insights tab.

The article recommends creating dedicated brand campaigns with exact match and phrase match brand keywords and running all non-brand activity in separate campaigns. According to groas, brand terms should be applied as negative keywords to non-brand campaigns to prevent bleed. The article states this separation is foundational campaign hygiene.

According to groas, the only defensible way to measure incremental brand value is a brand lift test that pauses brand campaigns for a controlled period of one to two weeks in a specific geography or daypart. The article recommends measuring total site traffic and conversions from branded queries and comparing paid plus organic volume during the test period against the baseline. The difference is the true incremental brand value.

The article recommends using exact match as the primary match type for brand campaigns and phrase match as a secondary layer to capture branded long-tail variations. According to groas, broad match should be excluded from brand campaigns entirely unless you have a very strong negative keyword list and are actively monitoring search term reports.

According to groas, brand and acquisition campaigns should have separate budgets because when they share a budget, cheap high-converting brand traffic eats first and acquisition campaigns starve. The article cites a shared-budget example with 70% brand allocation and 30% non-brand allocation showing a combined 500% ROAS, where split data often shows brand at 1000%+ ROAS while non-brand sits at 200% or lower. The article states this blended number hides the real cost of growth.
