Ad assets (Google’s updated term for extensions) are one of the most underused elements of travel PPC – and one of the most impactful. They expand your ad’s footprint on the SERP, give you additional space to communicate expertise and trust signals, and can meaningfully improve both click-through rates and conversion quality. For tour operators competing against OTAs with massive brand recognition, making the most of every pixel of ad space matters.
There’s no additional cost to run ad assets – you pay the same CPC as without them. The question is simply how well you’re using the space available.
What are ad extensions?
Ad assets are additional pieces of information shown alongside your core ad – links to specific pages, phone numbers, callout text, structured information, and more. They give searchers more reasons to click and more ways to engage, and they signal to Google’s Quality Score algorithm that your ads are relevant and well-structured. Well-configured assets can increase CTR by 10–15% in our experience, and in competitive travel categories, that lift compounds significantly over a campaign period.
Sitelinks
Sitelinks are among the most valuable assets for tour operators because they let you surface multiple parts of the booking journey in a single ad. Rather than sending all clicks to one landing page, you can offer searchers direct routes to the content most relevant to where they are in the decision process.
A sitelink setup we’ve found effective for destination-based tour operator campaigns: one link to the main destination/tour page, one to a specific departure calendar or availability page, one to your customer reviews or Trustpilot profile, and one to a destination guide or brochure download. This structure addresses the searcher who’s ready to enquire, the one who wants to check dates, the one who wants social proof, and the one who’s still in research mode – all within the same ad.
- The click pattern on your sitelinks is useful data in its own right – it tells you what your audience is most focused on at the point of search. If your “Check Departure Dates” sitelink consistently outperforms “View Itinerary,” that’s a signal about what’s driving their decision.
- Sitelinks need good ad rank to show – another reason to maintain high Quality Scores through relevant keywords and landing pages.
Callouts
Callout assets are short text snippets (25 characters each) that highlight specific claims about your service. In travel, these are an opportunity to pack your most compelling trust signals and differentiators into the ad. Generic callouts (“Expert Team,” “Great Value”) are weak because every operator uses them. Specific callouts earn attention because they’re credible and distinctive.
Travel callouts that consistently perform well in our accounts: “ATOL Protected,” “Guaranteed Departures,” “Max 12 Guests Per Tour,” “25 Years East Africa Experience,” “No Single Supplement,” “Award-Winning Guides.” These address the specific anxieties and priorities that travel buyers carry – financial protection, availability certainty, group quality, specialist expertise. Pick the ones that are genuinely true for your operation and rotate between them to let Google test which resonate most.
Structured Snippets
Structured snippets let you list specific features of your service under a defined category header – “Destinations,” “Tour Types,” “Services,” or similar. For tour operators, this is a useful way to show the breadth of your destination range or the types of experiences you offer, without it taking up headline space.
A “Destinations” snippet listing “Kenya, Tanzania, Rwanda, Uganda, Zimbabwe” immediately tells a searcher that you’re an East Africa specialist, not a generic travel company. A “Tour Types” snippet listing “Small Group, Private, Family, Self-Drive” helps searchers pre-qualify themselves before clicking. This pre-qualification function is valuable: it reduces irrelevant clicks and improves the quality of the traffic you’re paying for.
Call Extensions
For tour operators selling high-value tours, phone calls are often the highest-converting lead type – a conversation with a knowledgeable specialist closes better than an email thread. Call assets make it easy for searchers to call directly from the ad, and on mobile they’re particularly powerful because the friction between “clicking the ad” and “speaking to someone” is minimal.
- Schedule call assets to show only during your staffed hours – a click-to-call that goes to voicemail is a wasted lead, and in competitive categories, the traveller will simply call your competitor.
- Enable call reporting in Google Ads to track calls as conversions – phone leads that aren’t tracked mean your bidding strategy is under-counting conversions and under-bidding on the traffic that produces them.
- The CPC for a call asset click is the same as for a standard ad click – it’s a free upgrade to your ad format.
Message Extensions
Message assets allow searchers to send a pre-filled text message to your business directly from the ad. For tour operators targeting mobile users – particularly younger travellers who prefer messaging over phone calls – these can be an effective additional enquiry channel. The pre-filled message can be customised: “I’d like to enquire about [destination] tours” gives your team immediate context when a message arrives.
As with call assets, schedule message assets to show when you have coverage to respond quickly. A message that takes 24 hours to receive a reply fails the basic test of fast response that shortens the travel sales cycle.
Location Extensions
For tour operators with physical showrooms or offices where travellers can visit to discuss bookings, location assets add credibility and facilitate in-person sales conversations. Even operators without public-facing offices sometimes use location assets to signal that they’re a real, UK-based operation – which addresses the “are these people legitimate?” concern that some travellers carry when booking with a specialist operator they haven’t heard of before.
Promotion Extensions
Promotion assets highlight current offers within the ad – early-bird discounts, seasonal promotions, specific departure savings. In travel, these work best when they’re tied to genuine, time-limited offers that align with real booking behaviour: an early-bird offer closing in January (when the January planning window is at its peak), or a departure-specific discount on availability that genuinely needs filling.
Fake or permanently-running “promotions” damage trust once travellers notice they’re always available – and experienced travel buyers notice. Authentic urgency converts; manufactured urgency erodes credibility.
Automated Extensions
Google Ads automatically generates some assets from your website content and existing ads – including dynamic sitelinks, callouts, and image assets. These can be useful, but they’re worth reviewing regularly, since Google’s automatic selections aren’t always aligned with your messaging priorities or current offerings. Audit your automated assets periodically and exclude any that are off-brand or inaccurate.
Seller Ratings
Seller ratings show your average review score alongside your ad – sourced from Google Customer Reviews or third-party review platforms like Trustpilot. For tour operators, where trust is the primary conversion barrier, a high seller rating in the ad itself (before a searcher has even visited your site) is a significant advantage. A 4.8/5 rating next to your ad in a SERP full of OTA listings is one of the clearest signals that you’re a credible, experienced operator.
If you’re not actively collecting reviews in a way that feeds into Google’s seller ratings, it’s worth setting up. The incremental lift in CTR and conversion rate from a visible review score typically justifies the effort of a structured review collection process.
