SEO Test Shows 25% Uplift to Organic Traffic by Increasing Internal Linking on Ecommerce Site

In this SEO test, folks from SearchPilot added additional linking between level two and level three categories for an eComm site, by including buttons with links to level three category pages at the top of the level two category pages.

They then measured the impact during the testing period on three groups of pages, the level 2 category pages that were getting the additional level 3 category links added to them, the level 3 category pages being linked to, and the level 2 and 3 category pages combined. It resulted in a 25% uplift to organic traffic across level two and level three category pages – an additional estimated 9,200 organic sessions a month.

They also looked at the two page groups in isolation to confirm it wasn’t one group contributing to the uplift. Both page groups alone also had estimated uplifts in the 20%+ range, which means the increased internal linking also benefited the pages being linked from.
