A redesign is the occasion to keep the existing visibility of the website and make the most out of technical resources to start with better & saner SEO bases. It is an ideal time to fix all existing blocking issues in order to significantly improve performances.
Testing of recommendations on staging website and production site
In the first integrations and developments, it is necessary to grant your SEO team access to your staging site in order to correct potential technical or structural issues.
Plan at least 2 WEEKS of testing prior to the launch of the new website to make the right adjustments with your technical team.
Even during the launch, the website will be tested and monitored the following weeks after the release to ensure that the new version of the website has a good visibility.
