Changing URL's During a Site Redesign

[jennifer-garcia]

What are the effects of changing URL's during a site redesign following all of the important processes (ie: 301 redirects, reindexing in google, submitting a new sitemap) ?

Hi Jennifer,

Considering that you tackle everything needed in a migration (such as proper 301 redirects, new sitemaps and all that).. What you should spect in an organic traffic perspective:

1. Rankings will vary for some days while google is understanding the new site, hopefully wont take longer than a month.
2. Visits could be down for the time where rankings are fluctuating
3. Google will show both site in SERPs for some time

Keep in mind that this is a migration, like any other. So it could come handy these resources:

Hope it helps.
Best luck.
