Has anyone actually seen consistent gains from AI-assisted internal linking at scale?

I’ve been testing AI-assisted internal linking on a few niche sites over the last couple of months, and I’m curious whether others are seeing anything meaningful beyond the usual “it depends” answer.

My setup is pretty straightforward:

– WordPress sites
– Mostly informational content
– A mix of manually written and AI-assisted articles
– Internal links added through a combination of manual review and automation
– Focus on contextual links, not just sidebar/footer stuff

What I’m trying to figure out is whether AI is genuinely helping with link relevance and crawl depth, or if it’s just making it easier to spray links around without much benefit.

What I’ve noticed so far:

1. **On smaller sites, the impact seems modest**
– If a site only has 30–80 solid articles, manual linking still feels better.
– AI can suggest decent anchors, but it sometimes over-prioritizes exact-match phrases that don’t feel natural.

2. **On larger content clusters, the workflow benefit is real**
– Once you’re dealing with 300+ URLs, AI saves a lot of time.
– Even if the ranking lift is small, the operational efficiency is hard to ignore.

3. **Relevance is still the main issue**
– I’ve seen AI recommend links based on loose semantic similarity that wouldn’t make sense to a human reader.
– That’s where I think a lot of people overestimate the value of automation.

4. **Internal link structure matters more than volume**
– Pages with strong topical grouping and clean hub/spoke architecture seem to benefit more than pages that just get “more links.”
– This is probably obvious, but I still see people chasing raw link counts instead of structure.

I’m also testing whether AI-generated internal link suggestions work better when combined with a simple rules layer, like:

– only link between closely related categories
– avoid repeating the same anchor too often
– prioritize pages with impressions but weak clicks
– push links from stronger pages to newer supporting articles

That seems more sustainable than fully automated linking, but I’m not sure if it’s the best balance.

Has anyone here run a controlled test on this?

Specifically interested in:
– whether AI internal linking improved rankings or just crawl efficiency
– whether you use it for new content only or retroactive sitewide updates
– what tools or workflows
