Global SEO Strategy

I start with market selection, not technical setup. I look at search volume trends for my niche in each country, competitive density using tools like Ahrefs, and cultural fit. For example, when I expanded into Germany, I found that the keyword 'website optimierung' had high volume but low competition compared to 'SEO' — so I prioritised that market. I also check whether the local search engine matters. In China, Baidu dominates, so I would need a separate approach for [Baidu SEO](/baidu-seo/). In Russia, Yandex is the primary engine.

Once I have a shortlist of markets, I do dedicated keyword research for each. I never translate my English list. For France, 'agence SEO' might be the right term, but the French market also searches for 'référencement naturel' — two different intents. I use [International SEO Keyword Research](/international-seo-keyword-research/) to find demand and competition per market.

Then I decide the URL structure. ccTLDs are expensive but signal strong country targeting. Subdirectories with hreflang are cheaper and consolidate authority. I lean towards subdirectories for most projects because they keep link equity under one domain. But if the market is large enough to justify a separate brand, a ccTLD works. I document the decision in a strategy document so every team member knows why.

With structure set, I implement hreflang. I use self-referencing hreflang tags on every page, including the original. I also include x-default for the fallback page. I test the implementation using Google Search Console's URL inspection tool. After that, I create localised content. This is not just translation — it is [Localization SEO](/localization-seo/). I adapt examples, currency, units, and cultural references. For example, a page about 'best running shoes' in the UK uses miles, not kilometres.

Finally, I build local backlinks. I reach out to regional bloggers, directories, and news sites. [International Link Building](/international-link-building/) is slower than domestic link building, but it pays off. I track each market's authority separately using domain rating per country.

I also set up Google Search Console for each country and language. I monitor impressions and clicks by market, and I adjust content based on performance. The whole process takes about three months before I expect meaningful traffic from a new market.

The biggest watch-out is hreflang misimplementation. I have seen sites that use hreflang only for translated versions but forget to include a self-referencing tag for the original. Google then ignores the cluster entirely. Another common mistake is using incorrect language codes, like 'en-uk' instead of 'en-gb'. Use the ISO 639-1 language code and ISO 3166-1 region code. I always validate with the hreflang test in Google Search Console or a third-party tool.

Another trap: assuming one keyword research for the English market will guide global strategy. Search behaviour differs. In Japan, users search for 'SEO 会社' not 'SEO company'. If you translate your English keywords, you miss the natural language. I learned this the hard way — more on that in the next section.

Cultural tone is another watch-out. A direct sales pitch works in the US but can offend in Japan, where indirect, trust-building content is preferred. I always hire a native speaker to review content for tone, not just grammar. [SEO Translations](/seo-translations/) are not enough; you need cultural adaptation.

Don't forget local search engines. In China, Baidu doesn't use hreflang; it uses a separate sitemap. In South Korea, Naver requires its own registration. Ignoring these means missing entire markets. If you target China, you need Baidu SEO knowledge. For Russia, learn about Yandex.

Finally, watch out for duplicate content across language versions. Even with hreflang, if you have near-identical content for different regions, Google may treat one as a duplicate. I add at least 20% unique content per market — local statistics, references, or examples. This also helps with regional relevance.

Also, internal links should stay within the same language version. If you link from a French page to an English page, you confuse the user and the search engine. Use absolute URLs with the correct language prefix or subdomain.

I used to think that a single keyword research for the English market would be enough to guide global strategy. I was wrong. When I expanded an e-commerce store into France, I simply translated the English keyword list and built pages for those terms. Traffic from France was negligible for months. After digging into the data, I discovered that French users search for 'chaussures de course' not 'running shoes', and they use different queries for 'trail running' versus 'road running'. I had missed an entire segment of long-tail keywords.

The mistake went deeper. I had also assumed that the same content structure would work across markets. I modelled the French site after the UK site: same categories, same product descriptions. But French users expected more detail about materials and sizing, and they trusted third-party reviews more than brand claims. The bounce rate was high, and conversions were low. I had to redo the entire content strategy, this time with a native French SEO consultant.

Another error: I ignored local search engines. I focused on Google, but I later learned that Baidu holds over 60% market share in China. I had a client who wanted to target China, and I recommended standard hreflang. That was useless. Baidu doesn't support hreflang. I had to set up a separate Chinese domain and register with Baidu Webmaster Tools. That delay cost the client six months of visibility.

I also got the URL structure wrong. For a project targeting Germany and France, I used subdirectories with a ccTLD for the main domain. That worked fine. But for a Japan project, I used a subdomain and later realised that I should have used a ccTLD – Google treats subdomains as separate entities, and I struggled to build authority for the Japanese subdomain from scratch. Now I match the structure to the market maturity and budget.

Those mistakes taught me to do proper market research first, invest in local keyword research, and treat each market as its own project. Global SEO is not a single strategy; it is a collection of parallel strategies.
