1. Communicate all the resources a client will need to go international with their SEO from the beginning of the process – language translation, seasonality factors, international shipping for products etc. These may not be areas SEO’s traditionally advise on, but making your client aware of these factors will make your recommendations more useful.
2. Identify your profitable markets from the start and map your expansion. Look at search volume for your keywords and test some landing pages before so you don’t over-invest in a market.
3. Don’t assume the behaviour and preferences of your international audience. This means you’ll have to do keyword research. Even markets that speak the same language as you can have different behaviours.
4. Don’t use automated content translations e.g. Google translate. This needs to be done by a native speaker of the language in the market you’re targeting. If it seems like an expensive task, just start off small by getting a few pages translated to a high quality.
5. Measure each market you do in SEO independently, but also consider the interconnectedness of your markets.
