High traffic product pages with no internal links out - wasted authority
We often ignore the solution sitting right under our nose and go chasing harder ones.
Most ecommerce SEOs are out there grinding for backlinks. Meanwhile, the authority already on their own site sits there doing nothing.
If you've got product pages pulling in organic traffic, those pages have earned real authority over time. You can put that authority to work for pages you want to rank higher, through internal body links.
Here's how:
Open Search Console, pull the last 28 days, sort by clicks. Your top-performing product pages are your authority sources.
From those pages, drop contextual links in the body copy pointing to category pages or other products you want to push up. Not in the footer. Not tucked in a sidebar widget. In the body, where Google pays attention.
A few things that matter here:
Write anchor text that matches the target page's keyword. Not "click here" or "this product" - the actual keyword phrase.
Keep body links to around 3 per page. Any more and you're splitting the authority too many ways - everyone gets a smaller slice.
Don't point links at pages already sitting in positions 1–3. That's wasted. Aim at pages in positions 11–30 instead. Close enough to page one that a small push moves them.
One thing worth watching: don't link between pages competing for the same queries. That creates cannibalization. Link from a popular product to the category it belongs to, or to a complementary product, not a near-substitute.
Most sites have this sitting untouched. Takes an afternoon to map out. Costs nothing.
