Personalisation and Localisation

Personalization, Localization 12 minSearch results change with the searcher's location, language and device, and to a smaller degree with their own history, so there is no single ranking that everyone sees.

Personalisation and Localisation

Asha searches "plant nursery" at her desk in Pune, and Leafline's nursery appears on the map near the top. Delighted, she asks her cousin in Delhi to check. He sees a completely different list, with no Leafline anywhere. Neither of them is wrong. They are looking at different results pages.

The rule

There is no single ranking, only rankings for a place, language and person.

Search engines adapt results to the searcher's situation:

  • Location (localisation). Queries with local intent, such as "plant nursery", "repotting service" or anything with "near me", show nearby businesses, often on a map with a short list of places. Even without local words, the searcher's country and city shape the results.
  • Language and region. Someone searching in Hindi, or searching from another country, is served pages in that language or for that market.
  • Device. Phones and computers can see different layouts and features on the results page.
  • Personal history (personalisation). Some results can shift based on what the person searched for or visited before. For most everyday searches this effect is small compared with location and language.

Two consequences for SEO:

  1. "What position are we?" needs a place attached. A rank checked in your own browser, logged in, in your own city, is one sample, not the truth. Rank-tracking tools deliberately fix a location and a device for every check.
  2. Local visibility is its own discipline. For a business with a physical location, accurate listings, with its name, address and opening hours on maps and business profiles, matter as much as its pages.

The shortcut

Before trusting any ranking, name its three coordinates: where, which language, which device. A rank without them is a rumour.

Checking the nursery's visibility properlyStep 1 of 4
  1. Name the coordinates

    Where: Pune. Language: English. Device: mobile, because most people look for nurseries on their phones.

The trap: searching from your own logged-in browser, in your own city, and reporting that single view as "our position". It feels precise, but it is one sample out of many.

Remember

  • There is no single ranking: results depend on place, language, device and, a little, the person.
  • Name the three coordinates before trusting a rank.
  • The trap: checking rankings in your own logged-in browser and treating that as the truth.

ExplainWhy do our rankings disagree?

Leafline's intern reports 'we rank number 1 for plant nursery', while a customer in Mumbai says she has never seen Leafline in search. Explain how localisation and personalisation can make both statements true, and describe how Leafline should measure its rankings instead.
