Compare your performance

Compared against LocaliQ's Search Advertising benchmark dataset (Google Ads and Microsoft Advertising Search campaigns, combined) — not a Google-Ads-exclusive figure.

Industry

Benchmarks are directional context from third-party aggregated data, not guaranteed performance targets. Actual results vary by business, market conditions, and campaign execution.

How each metric is calculated

CTR (click-through rate): Clicks ÷ Impressions × 100
CPC (cost per click): Ad spend ÷ Clicks
CPM (cost per 1,000 impressions): Ad spend ÷ Impressions × 1,000
Conversion rate: Conversions ÷ Clicks × 100
CPA (cost per conversion): Ad spend ÷ Conversions
ROAS (return on ad spend): Revenue ÷ Ad spend; Shown as a multiple, e.g. 4.00x means $4 of revenue per $1 spent.

Worked example: a $1,500 search campaign

With $1,500 ad spend, 50,000 impressions, 2,000 clicks, 80 conversions and $6,000 revenue, the calculator shows CTR 4.00%, CPC $0.75, CPM $30.00, conversion rate 4.00%, CPA $18.75 and ROAS 4.00x. Leave revenue blank and only ROAS changes to “—”; every other metric still calculates.

Assumptions and limitations

Each metric needs both of its inputs. A blank, negative or non-numeric input, or a zero denominator, shows “—” instead of a guessed number.
Results are rounded to two decimal places for display. Inputs are not checked against each other, so a click count higher than impressions gives a CTR above 100%.
All figures are treated as one currency; the $ sign is a label and nothing is converted.
Industry comparison uses the LocaliQ 2026 search advertising figures (Google Ads and Microsoft Advertising, Search Network combined, region not stated by the source). Display, video and other non-search campaigns are not part of that dataset, so compare them with the display benchmarks instead.
Your CPA is compared with the industry cost per lead. That is like-for-like only when your conversions are leads; for purchases or sign-ups treat the difference as context, not a target.
CPM and ROAS have no benchmark in the source, so they are calculated but never compared.
