FAQ — Technical SEO
How is Technical SEO different from On-page SEO?
Technical SEO concerns the technical structure of the website: crawlability, speed, schema, security — things that the average user doesn't see. On-page SEO concerns content: title tags, meta descriptions, headings, keyword optimization. Both must work together for the best results.
How often does my website need to perform a Technical SEO audit?
We recommend a full audit 1-2 times per year and a mini-audit quarterly. For websites with frequent updates (e-commerce, news), weekly monitoring of Google Search Console errors is recommended. HelloAds offers monthly technical monitoring services for retainer clients.
Do Core Web Vitals really matter to rankings?
Yes, Core Web Vitals (CWV) is a ranking signal from Google (Page Experience update). Websites that meet CWV criteria better have a ranking advantage, especially when the content quality is similar to competitors. Besides ranking, good CWV also improves UX → increases conversion rate.
