Site migrations are probably not on most people’s fun list. Alas, sometimes they’re necessary to ensure the continued health of a website. Once you’ve decided you need to do a migration, it’s important to make sure you know what you’re doing and make a plan for how to approach things beforehand. Whether you’re moving from HTTP to HTTPS, switching your TLD, or moving to another domain: think about what you need to change, and make sure you can easily pinpoint the cause if something goes wrong.
In any case, take into account that you may experience lower traffic, the first few weeks after your migration, simply because your new URLs need to be properly indexed again. If everything goes well and you don’t break things, your rankings will improve over time. Let’s discuss a case where this might happen in some more detail in today’s Ask Yoast!
