A/B testing & SEO

This tells search engines such as Google that the redirect is temporary và that they should keep the original URL indexed rather than the demo URL.

Run experiments only as long as necessary: Running tests for longer than necessary, especially if you are serving one variation of your page to lớn a large percentage of users, can be seen as an attempt lớn deceive tìm kiếm engines. Google recommends updating your site and removing all test variations your site as soon as a thử nghiệm concludes and avoid running tests unnecessarily long.
