On the other hand, SEOs need to make sure they follow best practice and avoid common pitfalls in order to make sure traffic loss will be kept to a minimum.Disclaimer: The suggested site migration process isn't exhaustive and certainly there are several alternative or complimentary activities, depending on the size of the web site as well as the nature of the undertaken migration.
Whoishostingthis and Spy On Web can provide some really useful information.
Therefore, the migration shouldn't take place during busy times for the business or when time or resources are too tight.
If you're migrating a retail site, you shouldn't be taking any risks a couple of months before Christmas. If the site falls into the travel sector, you should avoid the spring and summer months as this is when most traffic and revenue is being generated.
This is certainly something no site owner wants to hear about, therefore play it as your last card and things are very likely to turn around.
No matter how proactive and organised you are, things can always go wrong.
