Native advertising glossary for travel marketers

Plain definitions of 29 native advertising terms for travel marketers, from cost per click to wave season, each with a travel example and a source.

This glossary defines 29 terms travel marketers meet when they buy native advertising. Each entry gives a plain definition, a travel example and a source, checked 23 Oct 2026.

One term to read with care is click-through rate. A high rate means the ad drew clicks, not that it brought bookings, which is why each site is best judged by its click-to-booking rate.

New to the channel? What native advertising is, and what an ad looks like covers the basics.

Ad formats and labels

Native advertising

Native advertising is paid advertising that matches the look and feel of the page or feed where it appears. A 2019 IAB playbook names three core types: in-feed ads, content recommendation ads and branded content. It says all three need a label showing they are paid.

The rules on labels differ by market:

US: the FTC's guide (Dec 2015) says "Ad" and "Paid Advertisement" are likely to be understood. It says advertisers should not use "Promoted", which it calls at best ambiguous.
UK: the ASA's advice (dated 23 Oct 2026) says people must know when they are looking at an ad.

Example: a tour operator places a labeled headline about walking trips in Portugal in a news site's feed. The click leads to a page about the trip.

Advertorial

An advertorial is a paid article written to read like the editorial content around it. In the UK, the ASA (23 Mar 2023) deals with content a brand pays a publisher to create, in money or in kind. That content is likely to fall under consumer protection law and need disclosure as advertising. If the brand also has editorial control, the CAP Code applies too. The ASA adds that the CAP Code names "Advertisement Feature" as an appropriate label.

In the US, the FTC (Dec 2015) says the page where the full ad appears needs its own clear label. People can reach that page without passing through the publisher's site. The exception is a page that is obviously an ad.

Example: a DMO pays for a "48 hours in the city" article that features partner hotels, labeled above the headline. Some native advertising campaigns send clicks to an advertorial first, then on to the brand's own site.

Recommendation widget

A recommendation widget is a block of headline links, below or beside an article, that mixes paid ads with links to other stories. A 2019 IAB playbook renamed these "content recommendation ads". It says a click always leads to an outside page or another page on the same site.

The FTC (Dec 2015) describes an ad styled like a site's own headlines, in a box headed "From Around the Web". It says readers are likely to take it for an independent news story. Where a widget mixes ads with links to stories, the FTC says each ad needs its own label. One label for a group of ads needs visual cues, such as shading or a border.

The ASA (dated 23 Oct 2026) says clear labels are likely to be needed if the context does not show which links are ads. It reports that CAP's Industry Advisory Panel suggested "paid-for ad", "ad" or "ad link" in 2014, placed near the heading.

Example: a hotel's headline about a spa weekend appears in a widget under a city news story.

Prices and rates

Cost per click (CPC)

Cost per click (CPC) is the price an advertiser pays each time someone clicks an ad. Google's definition separates the maximum an advertiser will pay from the "actual CPC" charged, which is often lower. Google notes that CPC pricing is also called pay-per-click (PPC).

CPC tells you what traffic costs, not what it earns. A low CPC can still mean a high cost per booking if few visitors book. Example: a tour operator pays per click on a headline about small-group trips to Japan. It then checks how many of those clicks turn into brochure requests.

Cost per thousand impressions (CPM)

Cost per thousand impressions (CPM) is the price of showing an ad 1,000 times, whether or not anyone clicks. The "M" is the Roman numeral for a thousand. Google describes CPM as paying per thousand views. It also offers viewable CPM, which charges only when an ad can be seen.

CPM moves the risk to the buyer: you pay for views even if nobody clicks. It suits campaigns meant to make a name known. Example: a DMO buys CPM ads to build awareness of a new winter festival before tickets go on sale.

Click-through rate (CTR)

Click-through rate (CTR) is the share of people who saw an ad and clicked it. Google gives the formula as clicks ÷ impressions, so 5 clicks from 100 impressions is a 5% CTR. Google adds that a good CTR depends on what you advertise and where.

CTR measures interest in a headline and image. It says nothing about whether a click turns into a booking. Example: a cruise seller tests two headlines for a Norway fjords sailing. If one gets more clicks but the other brings more brochure requests, the second is doing the job.

Conversion rate

Conversion rate is the share of ad clicks that end in the action you want, such as an inquiry or a booking. Google divides conversions by the ad interactions in the same period. Its example: 50 conversions from 1,000 interactions is 5%.

Google notes the rate can pass 100% when one click leads to several counted actions. So check what counts as a conversion before comparing rates. Example: a hotel counts a visit to its booking engine as a conversion. Its rate will look high next to a hotel that counts only paid bookings.

Cost per inquiry (cost per lead)

Cost per inquiry, also called cost per lead, is your ad spend divided by the number of inquiries it brought. An inquiry might be a brochure request, a quote form or a phone call. Google's cost per action formula works the same way: marketing cost divided by the number of actions.

The figure depends on what you count. A newsletter sign-up and a quote request are not the same inquiry, so count them apart. Example: a tour operator spends $2,000 in a month and gets 40 quote requests. That is $50 per inquiry. These numbers are an example, not a benchmark.

Cost per booking (CPA)

Cost per booking is ad spend divided by the bookings it brought. Ad platforms usually call it cost per acquisition or cost per action (CPA). Google gives the formula as marketing cost ÷ number of actions.

For travel brands, the hard part is counting the bookings. A booking can come days or weeks after the click, by phone or through an agent. So the count depends on tracking and on the attribution window.

Example: a cruise line divides a month's native advertising spend by the bookings traced to those ads. Phone bookings that follow a brochure request need their own route back to the ad.

Click-to-booking rate

Click-to-booking rate is the share of ad clicks that end in a booking. It is a conversion rate where the conversion is a booking. It also joins up the steps in between: click, inquiry and booking.

This worked example for a tour operator shows how the steps multiply. It is an example, not a benchmark:

1,000 clicks at $1 each cost $1,000.
4% of clicks send an inquiry: 40 inquiries, or $25 per inquiry.
10% of inquiries book: 4 bookings, or $250 per booking.
Click-to-booking rate: 4 ÷ 1,000 = 0.4%.

Halve the inquiry rate and the cost per booking doubles to $500, with the click price unchanged.

Pages and tests

Landing page

A landing page is the web page people reach after they click an ad. Google judges a landing page by its relevance and usefulness, how easy it is to use, and whether it meets what the ad promised. The FTC (Dec 2015) says a native ad's landing page needs its own label unless it is obviously an ad.

In native advertising, the landing page can be an advertorial rather than a booking page. A reader who clicked a story headline may expect a story, not a booking form. Example: a hotel's ad about a spa weekend should land on the spa weekend page, not the home page.

Split test (A/B test)

A split test, or A/B test, shows two versions of a page or ad to people at random and compares the results. Optimizely describes it as showing two variants at random, then using statistics to judge which does better against a goal.

The limit is traffic. With few clicks, a gap between versions can be chance, so a test needs enough visitors before anyone names a winner.

Example: a tour operator runs two advertorials for the same safari, one a story and one a list. Each gets half the clicks, and the one that brings more inquiries wins. On Itinex, two page versions run on an even split until the numbers name a winner (the platform).

Audiences and data

Retargeting pixel

A retargeting pixel is a small piece of code on a web page that records visitors, so an ad platform can show them ads later. Google now calls these audiences "your data", formerly "remarketing".

Consent rules differ by market:

UK: the ICO's guidance (29 Apr 2026) says tools that store or read information on a person's device need consent for online advertising. The ICO lists tracking pixels among them, alongside cookies.
US: California's CCPA (page updated 28 Aug 2026) lets people opt out of "sharing" for cross-context behavioral advertising.

Example: a cruise line shows a reminder ad to people who read its Alaska page but did not book. On Itinex, a client's own pixels can ride on its ads and its advertorial pages, with the reader's consent where it is required (the platform). In the UK and Europe, the network holds the ad pixels back without consent, and the pages ask first.

Lookalike audience

A lookalike audience is a group of new people chosen because they resemble a list of existing customers, called the seed list. Google's developer guide (updated 14 Oct 2026) says its lookalike segments are built from first-party data, such as lists of past customers. In the UK, the ICO (2 Apr 2026) says you must have a valid lawful basis to handle personal information.

From March 2026, Google began treating the seed list as a signal rather than a strict limit in Demand Gen campaigns.

The result follows the seed. A seed of brochure requesters looks for people like brochure requesters, not like bookers. Example: a hotel group seeds an audience with past guests who booked suites.

Contextual targeting

Contextual targeting places ads next to content on a related topic, based on the page rather than the person reading it. Google describes it as matching ads to sites using keywords or topics the advertiser chooses. Context alone is not native advertising. The ASA (dated 23 Oct 2026) says native advertising goes beyond a car ad next to a motoring article.

Example: a ski tour operator's ad appears beside articles about winter sports. The limit is timing, since a reader of a ski article may have booked this season already.

Intent data

Intent data is information suggesting a person is planning to buy, such as their searches or the pages they read. Google calls its version "in-market segments": people researching a product and actively considering buying. Travel signals include destination searches and reading trip guides. Signals age, so how recent they are matters.

Example: a cruise line reaches people who searched for Caribbean cruises in the past month. Itinex builds its audiences from intent signals, such as search terms and the newsletters people received from travel brands. It sees no names or email addresses (how we find travelers).

First-party data

First-party data is information a business collects directly from its own customers and visitors, such as bookings, inquiries and email sign-ups. Ad platforms let advertisers upload it to reach those customers again or find similar people. Google's Customer Match is one example. Since early March 2024, Customer Match lists no longer run on Google's partner sites or third-party exchanges in the EEA, the UK and Switzerland. They still run on Google's own properties.

Privacy law applies in both markets:

UK: the ICO (2 Apr 2026) says you must have a valid lawful basis to handle personal information.
US: California's CCPA (page updated 28 Aug 2026) gives people the right to opt out of the sale or sharing of their data.

Example: a tour operator uploads past guests' emails to leave them out of a first-trip offer.

Measurement and traffic quality

Invalid traffic (IVT)

Invalid traffic (IVT) is ad clicks or views that do not come from a real person with genuine interest. The Media Rating Council's June 2020 standard splits it in two. General invalid traffic is caught by routine filters, such as lists of known bots and data centers. Sophisticated invalid traffic needs deeper analysis. It includes hijacked devices, click farms and forced clicks.

Google also counts accidental clicks as invalid, and does not charge for invalid clicks it detects. Example: a DMO sees hundreds of clicks from one site but no partner referrals. That pattern is worth checking for IVT before blaming the ad.

Attribution window

An attribution window is the number of days after an ad click or view during which a sale or inquiry is credited to that ad. Google calls it a conversion window. Its default is 30 days, and it can be set from 1 to 90 days, depending on the source. Anything after the window is not counted.

If people take longer than the window to book, those bookings vanish from the report. Two platforms with different windows will report different results for the same campaign. Example: a cruise line whose guests book weeks after a brochure request needs a window long enough to catch them.

Travel trade terms

Co-op advertising (destination marketing)

Co-op advertising is a campaign paid for jointly by a destination body and its partners, such as hotels, attractions or airlines. The rules depend on who puts in the money:

US: Utah's Cooperative Marketing Grant (2026 guidelines) requires a 1:1 cash match. Tier 1 applicants, such as counties and DMOs, can request up to $215,000.
UK: VisitBritain's GREAT Gateway Innovation Fund 2026/27 asks for 2:1 matched funding, in cash and in kind. It also requires at least one airline or airport partner.

Example: a city DMO runs one campaign featuring five partner hotels, each paying a share. Each hotel will want to see what its share bought.

Wave season

Wave season is the cruise industry's main sales period, which generally runs from January to the end of March. The Points Guy (Jan 2025) describes it as when cruise lines run some of their most competitive sales.

In January 2026, Royal Caribbean Group reported "the highest seven booking weeks" in its history (earnings release, 29 Jan 2026). It credited Cyber sales and the start of wave season. Carnival Corporation (19 Dec 2025) called strong bookings from Black Friday to Cyber Monday "a favorable indicator for wave season".

Example: a river cruise seller has its ads and landing pages ready before January.

Online travel agency (OTA)

An online travel agency (OTA) is a website or app that sells other companies' hotels, flights or trips, often for a commission.

The UK's CMA (6 Feb 2019) secured changes from six hotel booking sites, including Expedia, Booking.com and Agoda. They agreed to say when commission affects how hotels are ranked, and to show compulsory charges in the headline price. The CMA made no finding on whether the sites had broken consumer law. It says their commitments are not an admission of a breach.

In hotel marketing, "native ads" can also mean paid placements inside an OTA's own search results. Skift reported in 2021 that Booking.com was testing them in destination searches. Example: a hotel pays an OTA commission on each booking while running its own ads to win direct bookings.

Destination marketing organization (DMO)

A destination marketing organization (DMO) is the body that promotes a city, region or country to visitors. Tourist boards and convention and visitors bureaus (CVBs) are both types. How DMOs are set up and paid for differs by market:

US: most money is public. A 2022 Destinations International post put public sources at 92% of destination organizations' revenue.
UK: in England, VisitEngland's Local Visitor Economy Partnerships (LVEPs) "lead, market and manage" their destinations. The program came from the government's response to an independent review of DMOs, the de Bois Review.

Example: a regional tourist board promotes its partner hotels and attractions to travelers in its main origin markets.
