Lost in translation: why your title tag wins could hurt you in other markets

Start here: how our SEO split tests work

If you aren't familiar with the fundamentals of how we run controlled AI discovery and SEO experiments that form the basis of all our case studies, then you might find it useful to start by reading the explanation at the end of this article before digesting the details of the case study below.

The result: adding affordability wording to title tags cut organic traffic by 4.6% on a Spanish-language travel site, despite repeatedly driving uplifts for travel customers in the UK.

What We A/B Tested

Title tags are one of the clearest signals search engines use to decide which queries a page should rank for. They are also the first thing a searcher reads in the results, so they can affect click-through rate as well as rankings.

Across SearchPilot travel customers in the UK, adding affordability wording such as “Cheap” or “Best deals” to title tags has repeatedly driven organic traffic uplifts up to 9%, likely because it appeals to budget-conscious travellers.

With that much evidence, it would be tempting to roll the change out everywhere but we wanted to confirm if these learnings translate across markets. So we tested it in a Eurozone-based customer market: a travel customer’s Spanish-language site, on their route pages.

What we changed

We added the phrase “Best deals” (translated into Spanish) to the title tags on this customer’s Spanish-language site, on their route pages. The phrase went at the very start of each title, ahead of the existing route, starting price and brand name.

Control: Madrid to Barcelona train tickets, Variant: Best deals on Madrid to Barcelona train tickets

What did we learn?

Actual variant sessions and the algorithm were well correlated, after the test started, variant sessions were lower than forecasted leading to a negative result

The % impact of the test was negative at the 90% credible interval The % impact of the test was negative at the 90% credible interval, with the range of impact being from -9% to 0%, the best estimate impact being -4.6%.

The test returned a 4.6% drop in organic traffic, which was significant at the 90% credible interval. That is a sharp contrast with the 9% uplifts the same type of change has driven for UK-based travel customers.

The UK wins came from separate tests on other SearchPilot travel customers, where affordability wording appealed to budget-conscious travellers. In Spain, the same idea lost, likely because of cultural differences in how affordability messaging is perceived. UK searchers respond well to this language, but searchers in this market may have read it as a signal of lower quality.

That doesn’t mean price messaging can’t work here. Small changes in wording can attract a very different audience, in the same way “certified pre-owned” appeals to different buyers than “used car”. Copy that stresses value or transparent pricing rather than cheapness could be the next thing to test in this market.

This test shows why a win in one market isn’t proof that a change will work everywhere. Results can differ between markets for several reasons. User preferences vary, so wording that signals value to one audience can signal low quality to another. Search results pages differ too: the SERP features, ads and pricing information shown next to your listing change by country and language, which affects how much a title tag stands out. And the competitors ranking alongside you are different, so copy that sets you apart in one market can blend in, or look out of place, in another.

That’s why we recommend testing changes in each market and rolling them out selectively based on what works there. A loss like this isn’t a dead end: it tells you what this audience doesn’t respond to and points to the next test to run.

How our AI discovery and SEO split tests work

The most important thing to know is that our case studies are based on controlled experiments with control and variant pages:

  • By detecting changes in performance of the variant pages compared to the control, we know that the measured effect was not caused by seasonality, sitewide changes, Google algorithm updates, competitor changes, or any other external impact.
  • The statistical analysis compares the actual outcome to a forecast, and comes with a credible interval so we know how certain we are the effect is real.
  • We measure the impact on organic traffic in order to capture changes to rankings and/or changes to clickthrough rate (more here).
