Tricks to reindex old content for LLM discoverability

[itsme75]

I was wondering if anyone had any tricks to get Google and the likes to update older content that has new comments to trigger better LLM visibility?

I was thinking about using an indexer tool, even though it's already been indexed, to try to see if I can get Google to see there's new content there.

Has anyone tried something like this? If so - any tips, did it end up working?

I’ve tried something similar before. Indexers can help Google recrawl a bit faster, but the impact isn’t always very noticeable. From my experience, small content structure updates, adding internal links, or tweaking schema tend to trigger recrawls more effectively.

Indexers usually don’t help much for already indexed pages. Google tends to re-crawl when it sees real signals, not forced ones.

What works better is updating the main content itself, improving internal links to that page, and linking to it from recently updated pages. Even small meaningful edits + fresh internal links often trigger a recrawl faster than tools.

If it's your site... then update the post update date and google will re-crawl it or use GSC.
If you don't own the site... Indexers did the job for me.

If it isn't already so, link to the new updated content direct from your home page (or most backlinked page/hub if it isn't the home page) in the guise of 'recent updates'. This should be enough, but if it isn't, it generally indicates poor authority for the site, which can be remedied by building more links to your home page with branding/entity recognition in mind.

A working indexer service will generally get the new updated content indexed as long as it triggers a Googlebot visit, but that doesn't mean it will be immediately visible to LLM chatbot searches.

Updating on-page content, internal links, and last-modified dates helps more than indexer tools; comments alone rarely trigger re-crawling.

Yes content post date plays vital role in AI's LLM algorithm and searches in SERP. Refresh your content so that it gets visibility by the AI crawler. AI algorithm needs fresh content.

Comments help only if they introduce new entities the page didn’t mention before. Ten “thanks” replies do nothing; one detailed user story can change how models classify the topic, and in my case that was enough to get a recrawl within days.
