A suggested route
Read the first entry before anything else: the rest assume you know why localisation goes further than translation. From there, keyword research and hreflang belong together, since one decides the words and the other makes sure each page reaches the right readers. Site structure and duplication pair up next, because most duplication problems begin with a structural decision. Leave content localisation for when a first market is chosen and translators are about to start work.
How the journal is kept current
Rules on age checks, privacy and marketing change across Europe every year, and search engines update their guidance too. Each entry shows the date it was last revised, and we revisit them whenever a regulator, court or search engine changes something they rely on, in any market we cover. If you spot something out of date, the contact page reaches us directly, and we will correct it with a note of the change.
Who the journal is for
These guides are written for the owners, marketers and developers at lawful adult businesses planning to sell or publish in more than one language. They assume no knowledge of other languages, and they explain each technical term the first time it appears. Each one stands alone; start with the one that matches your next decision, whether that is a first market or a fifth, then follow the links to the others where topics meet. If you would rather have the work done for you, the services are described on website localisation and multilingual SEO.
