FAQ

What's the difference between Technical SEO and On-page SEO?

Technical SEO addresses the structural health of your website — crawlability, speed, schema, security. On-page SEO covers content elements — title tags, meta descriptions, headings, keyword optimization. Both are required for strong rankings.

How often should I do a Technical SEO audit?

A full audit is recommended 1–2 times per year, with quarterly mini-audits for active sites. E-commerce and news sites should monitor Google Search Console errors weekly. HelloAds offers monthly technical monitoring as part of retainer packages.
