The pages that bring the most traffic to a software company are usually the ones least likely to produce a customer: broad guides, definitions and trend posts read by students, job seekers and other vendors. Meanwhile the searches that come just before a trial or a demo, such as a product compared with a competitor, an alternative to a tool someone is leaving, or an integration with a system they already run, are small, specific and often unanswered.
So a traffic chart can rise for a year while signups stay flat. The fix is to start from the account, not the visit: which searches did paying customers run, which page answered them, and can the signup or demo form say where each one came from?
That is the method we use for our own site and the one we would use on yours: research the phrases buyers run while they compare, build the pages that answer them, verify every page technically, and read Search Console against the trials and demos your systems record.
