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

I’ve been testing a few internal linking workflows across a couple of niche sites over the last few months, and I’m curious whether others are seeing anything similar.

The short version: AI can definitely help identify link opportunities faster, but I’m not convinced the “fully automated internal linking” pitch is as clean as some tools make it sound.

What I’ve tried so far:
– Running content through an AI workflow to suggest contextual links based on entities and topical relevance
– Using a spreadsheet-based system to map hub pages, supporting articles, and orphaned pages
– Testing manual approval vs. semi-automated insertion
– Comparing pages with added internal links against similar pages left untouched

A few observations:
1. The biggest win is not raw link volume, but better placement
Links inserted into genuinely relevant paragraphs seem to perform better than sitewide “related posts” style blocks.

2. Over-automation can get messy fast
Some AI suggestions were technically relevant but still felt forced. That may not hurt users immediately, but it does make the content look less natural.

3. The real value seems to be in finding missed opportunities
For older sites with a lot of content, AI is useful for surfacing pages that never got linked properly in the first place.

4. Results are not always easy to isolate
A ranking bump can come from internal links, content refreshes, crawl improvements, or just normal volatility. So I’m trying not to overclaim causation.

I’m still leaning toward a hybrid approach:
– AI for discovery and prioritization
– Human review for placement and anchor text
– A simple internal linking structure built around topic clusters rather than chasing exact-match anchors everywhere

What I’m still unsure about is whether anyone has a repeatable process that actually scales without turning the site into a mess.

Questions for the group:
– Are you using AI for internal linking on live sites?
– Do you let it auto-insert links, or just suggest them?
– Have you seen measurable ranking or crawl improvements?
– Any tools/workflows you trust more than others?

Would be interested in hearing real-world results, especially from people managing larger content sites rather than just small test projects.
