Frequently Asked Questions

How important is on-page SEO?

Critical. On-page work accounts for 30-40% of ranking impact and is the part you have 100% control over. Off-page (backlinks) and technical contribute the rest.

Should I use an SEO plugin?

Yes — Yoast or Rank Math on WordPress, or built-in tools if you're on Webflow/Framer. They catch ~70% of on-page issues automatically.

How often should I update on-page SEO?

Refresh top-traffic pages every 6 months. Refresh pages that have dropped rankings within 30 days of detection. Don't touch pages performing well — there's no positive ROI in fixing what works.

What's the most overlooked on-page SEO factor?

Internal linking. Most sites have 1-2 internal links per page when they should have 5-8. Strong internal linking can boost rankings 20-30% without any new content.
