What SEO change looked small but made a bigger difference than expected

Sometimes a small improvement in content clarity can have a bigger impact than expected. Better headings, clearer explanations, and answering the main question earlier can make the page much more useful to visitors.

For me, cleaning up old anchor text made a bigger difference than I thought. Just changed a bunch of "click here" links to proper keyword anchors on old posts, nothing else touched, and rankings moved within a few weeks.
