Search intent tiering: high vs mid vs low intent

The three intent tiers

Tier	Query language	Searcher's stage	Conversion expectation
High-intent commercial	"buy", "price", "near me", brand+product, comparison shopping	Ready to transact	5-15% on a strong landing page
Mid-intent research	"best", "reviews", "vs", "how to choose", "guide"	Evaluating options	1-3% on a comparison/review landing page
Low-intent awareness	"what is", "why does", problem-symptom queries, broad category	Identifying problem or category	Often 0% direct, 5-15% to email capture

Why tiering matters

Without tiering, every non-branded keyword competes for the same budget at the same bid strategy. The high-intent keywords are under-bid (you should be paying more for "buy [product]" than for "what is [category]"). The low-intent keywords are over-bid (you're paying $15 for a click that converts to email at 5%, not to sale at all). Net effect: budget bleeds toward keywords with worse economics, and the campaign as a whole underperforms.

With tiering, each tier runs its own economics. High-intent gets aggressive bidding and a buy-now landing page. Mid-intent gets a softer CPA target and a comparison landing page. Low-intent gets the lowest bids and an educational landing page focused on email capture.

How to tier your keyword list

Practical heuristic:

1. High-intent: contains a transactional verb (buy, order, get, find), a price modifier (cheap, affordable, $X), a location modifier (near me, [city]), or a brand+product combination.
2. Mid-intent: contains a research modifier (best, top, reviews, vs, compared), a recommendation modifier (recommend, suggested), or a decision-aid modifier (how to choose, which, guide).
3. Low-intent: contains a question word (what, why, how), a problem-symptom description, or a category-level descriptor without commercial language.

Edge cases: "[brand] reviews" is mid-intent if the searcher is evaluating you against competitors, high-intent if they're checking reviews before buying. Decide based on your typical user behavior or split test.

Campaign structure for tiered intent

Three separate campaigns minimum, often more if you have product lines or verticals to split:

Campaign	Bid strategy	Landing page	Negative keywords
High-intent	Target ROAS or Maximize Conversion Value	Product or pricing page with primary CTA	All mid-intent and low-intent query patterns
Mid-intent research	Target CPA at a softer threshold	Comparison or buyer's-guide page with both primary CTA and email capture	High-intent transactional patterns and low-intent awareness patterns
Low-intent awareness	Maximize Clicks within capped budget	Educational article with email capture as primary CTA, soft secondary CTA to product	High-intent and mid-intent commercial patterns

The negative-keyword pattern

Mutually-exclusive negatives prevent the same query from triggering ads in multiple campaigns. Without this, a high-intent campaign could trigger on a mid-intent query and over-bid for it. Pattern:

• High-intent campaign has: "best", "reviews", "vs", "how to choose", "what is", "why", "how to", "guide" as negative phrases.
• Mid-intent campaign has: "buy", "price", "cheap", "near me", "what is", "why" as negative phrases.
• Low-intent campaign has: "buy", "price", "cheap", "best", "reviews", "vs" as negative phrases.

Audit weekly. New search-term variants will trigger cross-tier; add them to the appropriate negative lists.

Budget allocation across tiers

Typical mature account split: 50-65% high-intent, 25-35% mid-intent, 5-15% low-intent. The exact mix depends on category. Commodity categories (consumer goods) skew higher to high-intent because the funnel is short. Considered-purchase categories (B2B, healthcare, financial) skew higher to mid- and low-intent because the funnel is long and education matters.

Measurement across tiers

Last-click attribution understates the value of mid- and low-intent traffic. A searcher who reads your "what is X" article today may not convert from that visit, but if they convert via brand search 30 days later, last-click credits brand and ignores the awareness content. Use data-driven attribution or position-based attribution to give partial credit to mid- and low-intent touches.

For low-intent campaigns, track email-capture conversions and downstream conversion from those emails as the success metric. Direct ROAS will look terrible; lifecycle ROAS may be excellent.

Landing pages by tier

The most-skipped optimization. The same landing page does not serve all three tiers:

• High-intent wants: clear pricing, a buy button, social proof above the fold, fast load. Friction kills high-intent conversion.
• Mid-intent wants: comparison content, third-party validation (reviews, ratings), a buyer's-guide structure that walks through trade-offs, both a primary buy CTA and a secondary email-capture CTA.
• Low-intent wants: educational content that answers the searcher's question, soft email capture (newsletter or guide download), a clear path to deeper content for engaged readers.

Can I run all three tiers in one campaign with different ad groups?

Technically yes. Practically, no. Different tiers want different bid strategies (and Google Ads applies bid strategies at the campaign level, not ad group level). Different tiers want different daily budgets. Different tiers want different conversion goals. Separate campaigns are the cleaner architecture.

How big is the lift from intent tiering?

For accounts that haven't tiered, expect 20-40% improvement on non-branded ROAS within 60 days of implementing tiering, mostly from re-allocating budget away from low-intent traffic that was eating spend without converting. Larger lifts are common in accounts with broad keyword lists or heavy DSA usage.

Do I need separate tracking for each tier?

Each tier should be tagged in your UTMs (utm_campaign = brand vs ni-high vs ni-mid vs ni-low) so you can break out reporting in GA4 and your CDP. Conversion goals can be shared across tiers — just the reporting needs to segment.

Where does Performance Max fit in tiered intent?

PMax behaves like a multi-tier campaign with the operator giving up direct control over the tier mix. With brand exclusions on, PMax mostly operates in mid- and low-intent space across surfaces; with brand exclusions off, it cannibalizes high-intent brand search. Run Search at the three tiers explicitly; let PMax run alongside for surface diversity and discovery.

How does intent tiering map to the AIDA funnel?

High-intent ≈ Action stage. Mid-intent ≈ Desire/Interest stage. Low-intent ≈ Attention/Interest stage. Tiering is essentially funnel-stage targeting in Search-specific language. The advantage of using intent terms over funnel terms is that intent describes what the searcher just typed, which is objective; funnel stage requires interpretation.

How often should I re-tier the keyword list?

Quarterly review of intent assignment, weekly review of search-term reports to add new variants. Intent of a query can shift over time — "what is X" may have been low-intent in 2022 but mid-intent in 2026 if the category has matured.

Operating checklist

1. Map every keyword to one of three intent tiers before opening Google Ads.
2. Set tier-specific bid strategies, budgets, and landing pages.
3. Build mutually-exclusive negatives between tiers.
4. Verify each tier's CPA target matches its expected conversion rate.
5. Pull search-term reports weekly; re-tier keywords as intent shifts.
6. Run incrementality tests against each tier quarterly.
7. Document the tiering taxonomy in a runbook your successor can read.
