The tactic that's had the biggest impact for me is improving pages that are already getting impressions instead of constantly publishing new content. I regularly check Search Console for keywords where a page ranks around positions 8–20, then expand the content, answer missing questions, strengthen internal links, and update outdated sections. Those pages often move much faster than starting from scratch because Google already understands the topic. It's not the most exciting strategy, but it's been one of the most reliable for increasing organic traffic over time.
