A product landing page does two jobs that pull in opposite directions. It has to persuade a visitor who arrived mid search, and it has to answer the follow up questions that persuasion creates: will this work with my stack, how long does setup take, what happens when I hit a limit. Most teams staff the first job and leave the second to the support team, who then answer the same five questions in chat for the next twelve months.
The fix is structural rather than editorial. Google's documentation on how search works sets out three stages (crawling, indexing and serving) and is explicit that the vast majority of pages in the index were found automatically by crawlers following links, not submitted manually (Google Search Central). That single fact decides the shape of your routing: a help article that nothing on the site links to is a page a crawler may never reach, and a reader definitely will not.
Internal links are hyperlinks from one page on a domain to another page on the same domain, and they do three things at once: they let visitors navigate, they establish the information hierarchy of the site, and they spread ranking potential between pages (Mozilla's internal link guide). Your landing page is usually one of the most linked to and most visited pages you own. Spending a few of its outgoing links on help content is the cheapest routing decision available to you.
There is a second audience worth naming. Pages that are crawlable, well structured and internally connected are also the pages AI answer systems can retrieve and cite, which is why technical hygiene matters for answer engines as well as classic search (Ahrefs technical SEO guide). A buyer who asks a chat assistant whether your product does something specific is often reading a retrieved passage from your help center, not your home page.
