Hi Mozzers,
Hope you're doing good. Well, we have a website, up and running for a decent tenure with millions of pages indexed in search engines. We're planning to go live with a new version of it i.e a new experience for our users, some changes in site architecture which includes change in URL structure for existing URLs and introduction of some new URLs as well.
Now, my question is, what's the best way to do a A/B test with the new version?
We can't launch it for a part of users (say, we'll make it live for 50% of the users, an remaining 50% of the users will see old/existing site only) because the URL structure is changed now and bots will get confused if they start landing on different versions.
Will this work if I reduce crawl rate to ZERO during this A/B tenure? How will this impact us from SEO perspective? How will those old to new 301 URL redirects will affect our users?
Have you ever faced/handled this kind of scenario? If yes, please share how you handled this along with the impact. If this is something new to you, would love to know your recommendations before taking the final call on this.
Note: We're taking care of all existing URLs, properly 301 redirecting them to their newer versions but there are some new URLs which are supported only on newer version (architectural changes I mentioned above), and these URLs aren't backward compatible, can't redirect them to a valid URL on old version.
