Step-by-step guide to fixing the most common technical SEO issues: canonical tags, schema markup, Core Web Vitals, heading structure, meta tags and crawl errors. This guide covers the key principles and shows you how to action them using Seotific — free during beta.
In order of ranking impact: pages blocked by robots.txt or noindex (prevents indexing entirely), canonical pointing to wrong URL (splits authority), missing H1 (weakens topical signal), broken internal links (wastes crawl budget), missing schema (misses rich result eligibility), slow Core Web Vitals (confirmed ranking signal).
A self-referencing canonical tag () tells Google this is the authoritative version. Issues arise when: canonical points to a different URL (splits authority), canonical is missing (Google chooses its own canonical, often incorrectly), or www and non-www versions both have no canonical.
The three Core Web Vitals are: LCP (Largest Contentful Paint — how quickly the main content loads, aim <2.5s), CLS (Cumulative Layout Shift — how much the page jumps around, aim <0.1), and INP (Interaction to Next Paint — how quickly the page responds to clicks, aim <200ms). LCP is fixed by preloading the hero image and reducing TTFB. CLS is fixed by adding width and height attributes to all images.
After generating schema with Seotific, paste the JSON-LD into Google's Rich Results Test (search.google.com/test/rich-results). Green = valid and eligible for rich results. Red = errors that prevent rich results. Common errors: FAQPage missing mainEntity, Article missing author or datePublished.
