Google Ads gives you a huge amount of data to work with — which is a good thing, until it isn’t. Clients often ask us which metrics they should actually be focused on, and the honest answer is that it depends on your campaign stage and objectives. But there are a core set of metrics that we track for every travel PPC campaign we run, regardless of whether we’re working with a tour operator, a ferry company or an activity provider. Here’s how to read them and what they actually mean for travel.
Number of Impressions
An impression is recorded every time your ad appears on a search result page or a Google Network site. For travel campaigns, impression volume tells you whether your ads are showing up during the key planning windows — for example, are you visible in January when summer sun searches spike, or in October when ski holiday searches start picking up? If impressions are low, you’ve usually got a budget, bid or match type issue worth investigating. If they’re high but nothing else is performing, that’s when you look downstream.
Clicks and CTR
Click-through rate (CTR) measures clicks as a proportion of impressions. In our experience, travel CTRs tend to vary significantly by campaign type — branded campaigns regularly hit 10–15%, while generic destination or activity searches are lower, sometimes 3–5% on a well-optimised campaign. A low CTR usually points to one of three things: your ad copy isn’t compelling enough, you’re targeting too broadly, or your competitors are bidding more aggressively on the same terms. What we’ve found is that travel-specific ad copy — mentioning departures, specific destinations, or direct booking benefits — consistently outperforms generic ad text.
CPC and CPA
Cost-per-click (CPC) and cost-per-acquisition (CPA) are where PPC becomes directly tied to your business performance. CPC tells you how much each click costs; CPA tells you how much each conversion (enquiry, booking, or lead) costs. For travel, CPA benchmarks vary enormously — a short activity booking has very different economics to a long-haul escorted tour. We always set CPA targets relative to average booking value, not as an absolute figure. If a tour operator’s average booking is £2,500, a CPA of £80 is very different in value terms to the same CPA for a day trip at £60. This context is essential for making smart bidding decisions.
Quality Score
Quality Score is Google’s assessment of your ad relevance, expected CTR, and landing page experience. A higher Quality Score generally earns you better ad positions at lower CPCs — so it directly affects your return on ad spend. We tend to see Quality Score issues most often when there’s a mismatch between keywords, ad copy and landing page content. For travel, this is especially common when operators use generic landing pages for specific tour searches. If someone searches for “self-guided cycling tours in France” and lands on a general activity holidays page, Quality Score will suffer — and so will conversion rate.
Focus on your business goals
The most important thing to remember about Google Ads metrics is that they’re only meaningful in the context of your actual business goals. Impression share matters if you’re in a competitive OTA-dominated market and visibility is the primary challenge. CTR matters most when you’re trying to qualify traffic and reduce wasted spend. CPA matters most when you’re managing a fixed budget against a booking target. What we’ve found working with travel clients is that problems often arise when teams focus on the wrong metric for their current campaign stage — optimising for impressions when the real issue is conversion rate, or chasing low CPA when the priority should be volume during peak season. Get the metrics hierarchy right first, and the optimisation decisions become much clearer.
