How to Fix: Local keyword research

Local keyword research is an important SEO check in the International SEO category. This is a high-priority SEO issue that should be addressed soon. It has a significant impact on your SEO performance.

What this check is really asking

This check verifies that your keyword targeting is grounded in how people in each specific market actually search — not in a single home-market keyword list translated word for word. When you sell into more than one country or language, the terms that convert are rarely the literal translations of your English keywords. Local keyword research is the work of finding the real phrase a real person in Munich or Mexico City types, in their own words, with their own intent.

When this check fails, it usually means one of two things: you are targeting the same keywords everywhere regardless of market, or you translated your keywords instead of researching them. Both leave you optimising for phrases your audience does not use.

Why translated keywords quietly fail

Search intent does not translate. It localises. The literal translation of a high-volume English term can be a phrase nobody in the target country would ever type — they use a borrowed English word, a regional synonym, or a completely different framing of the same need. Get this wrong and you rank beautifully for words with no searchers behind them.

• Different markets use different words for the identical product or service
• Search volume and competition for the “same” term vary wildly by country
• Local intent — what someone expects to find when they search — shifts across cultures
• Currency, units, spelling conventions and even seasonality change what converts

I learned this shipping software in six languages

Let me put my age on the table, because this lesson is old and it cost me. Back in the multimedia era I built multi-language CD-ROM projects — the same title pressed in six languages onto one disc. The first time, we did the naive thing: built everything in one language, then handed the strings to translators to swap in. It was a disaster. Menus overflowed their buttons because German words are longer. A label that was a friendly instruction in one language read as a command in another. Sorting order broke. We had treated language as a coat of paint you apply at the end.

The fix was to stop translating and start building each language as its own first-class thing from the source. Local keyword research is that exact lesson, thirty years later, wearing an SEO hat. You do not translate an English keyword list into German. You research how Germans search, in German, from scratch — the same way we learned to author each CD-ROM language as its own build instead of a translation layer bolted on at the end. The systems change; the mistake and its cure do not.

How to Fix This in WordPress

Difficulty Level: MEDIUM – This fix requires some technical knowledge or familiarity with WordPress settings and plugins.

Estimated Time: varies

Step 1: Research each market natively

For every target country or language, do keyword research in that language, using local search-volume data — set your keyword tool to the specific country and language, and where you can, get a native speaker to sanity-check the terms. Look at the local autocomplete and “people also ask” for the market. You are hunting for the phrase locals actually use, not the one your dictionary offers.

Step 2: Map keywords to a proper multilingual structure

In WordPress, run your international content through a real multilingual setup — Polylang or WPML, or a Multisite network per market — so each market’s pages carry its own researched keywords in titles, headings and copy. Do not machine-translate one page and hope. Give each language its own optimised page.

Step 3: Signal the targeting with hreflang

Implement hreflang annotations (WPML and Polylang generate these, or your SEO plugin can) so Google serves the right language version to the right market and does not treat your localised pages as duplicate content. This is the technical half of the job; the keyword research is the other half, and neither works alone.

Step 4: Verify the fix

1. Confirm each localised page targets market-specific keywords in its title and headings
2. Validate hreflang with Search Console’s International Targeting report or an hreflang tester
3. Clear your WordPress cache if you’re using a caching plugin
4. Re-run the SEO Roadmap audit, then watch per-market impressions in Google Search Console over the following weeks

Common Mistakes to Avoid

• Translating keywords instead of researching them in the target language
• Using global search volume when local volume tells a completely different story
• Shipping localised pages with no hreflang, so Google flags them as duplicates
• Assuming one Spanish page serves Spain, Mexico and Argentina equally — regional terms differ
