The useful first step doesn't happen on the pages. It's deciding which questions you want to be the cited answer for. Lean Labs, a HubSpot agency, describes its AEO process as starting there. It builds a managed question set from HubSpot sales calls, CRM insights, Search Console demand and competitor prompts, and then writes the answers in HubSpot. If your team logs calls and deal notes in HubSpot, part of that material is already in your account.
With the list in hand, match each question to a page you've already published before you plan a new one. A blog that has run for several years has often touched the same question more than once, in posts written years apart.
Suppose buyers keep asking how long implementation takes for a team of about 50. Suppose your blog has three posts written to answer that same question, from 2021, 2023 and 2024, and none of them states a number. The 2023 post is the most complete of the three and also gets the most search traffic. In that case you'd keep the 2023 URL, put a direct answer near the top, add the figure your customer success team can stand behind, and say what it's based on. You'd bring over anything from the other two posts that's still true, then retire those two and redirect them to the one you kept.
You'd then have one complete page where there were three partial ones, at an address search engines already know.
