Not all of the keywords the SEO team has pulled will rank immediately - but your Growth Lead should keep an eye out, and, once your site and business have been live for a couple of weeks or months, they should analyse the results.
They should monitor the number of ranked keywords and look at opportunities to further capitalise on those keywords with experimentation. On the other hand, if nothing seems to be ranking, your Growth Lead should work with the SEO team on a new strategy.
