What does an international SEO consultant actually do?

An international SEO consultant gets the right version of a site in front of searchers in each country or language. The work rests on a few decisions that Google sets out in its guide to managing multi-regional and multilingual sites:

URL structure. A country domain (example.de), a subdomain (de.example.com) or a subfolder (example.com/de/). Google lists the trade-offs: a country domain gives the clearest geotargeting but costs more to run and targets one country only, while a subfolder is easy to set up and maintain on one host.
Separate URLs per language. Google recommends a different URL for each language version, rather than switching content with cookies or browser settings, with hreflang annotations telling it which version is which.
No automatic redirects by guessed language. Google advises against redirecting visitors to a language version based on what you think they want, because it can stop people and search engines seeing every version.

When you are choosing someone for this work, ask how they would handle those three decisions on your site, and whether they can show you a site where they did it.
