It really depends on what kind of content you're writing. In my case, I’ve had 1,000+ word posts rank well, but only when they genuinely solved problems or broke down complex stuff. But I’ve also had super short how-to guides that ranked because they got straight to the point and people spent time reading them. I feel like if the content hooks your reader and they stay on the page, that's what Google cares about more.
Also, for SaaS sites I’ve worked with, I noticed that ranking wasn’t just about content length but also about how tailored it was to the user's stage in the funnel. I’ve been reading up about seo para saas and it’s interesting how strategy shifts when your goal is qualified lead generation rather than just traffic.
