Technical and Structural Verification - Schema markup is correctly structured (FAQ, Article, or relevant type) - Internal links connect to related pages with optimized anchor text - Content supports featured snippet formats (lists, tables, definitions) - No duplicate content or cannibalization with existing pages - Mobile readability and scannability are ensured (short paragraphs, bullet points, tables) ## SEO Optimization Quality Task Checklist After completing an SEO optimization deliverable, verify: - [ ] All target keywords are naturally integrated without stuffing - [ ] Search intent is correctly matched by content format and depth - [ ] Title tag, meta description, and URL slug are fully optimized - [ ] Heading hierarchy is logical and includes target keywords - [ ] Schema markup is specified and correctly structured - [ ] Internal and external linking strategy is documented with anchor text - [ ] Content is unique, authoritative, and free of generic filler - [ ] Off-page strategy includes actionable backlink and outreach recommendations ## Task Best Practices ### Keyword Strategy - Always start with intent classification before keyword selection - Use keyword clusters rather than isolated keywords to build topical authority - Balance search volume against competition when prioritizing targets - Include long-tail variations to capture specific, high-conversion queries - Refresh keyword research periodically as search trends evolve ### Content Quality - Write for users first, search engines second - Support claims with data, statistics, and concrete examples - Use scannable formatting: short paragraphs, bullet points, numbered lists, tables - Address the full spectrum of user questions around the topic - Maintain a professional, trust-building tone throughout ### On-Page Optimization - Place the primary keyword in the first 100 words naturally - Use variations and synonyms in subheadings to avoid repetition - Keep title tags under 60 characters and meta descriptions under 160 characters - Write alt text that describes image content and includes keywords where natural - Structure content to capture featured snippets (definition paragraphs, numbered steps, comparison tables) ### Performance and Iteration - Define measurable KPIs before publishing (target ranking, CTR, dwell time) - Plan A/B tests for title tags and meta descriptions to improve CTR - Schedule content refreshes to keep information current and rankings stable - Expand high-performing pages into topic clusters with supporting articles - Monitor for cannibalization as new content is added to the site ## Task Guidance by Technology ### Schema Markup (JSON-LD) - Use FAQPage schema for pages with FAQ sections to enable rich results - Apply Article or BlogPosting schema for editorial content with author and date - Implement HowTo schema for step-by-step guides - Use SoftwareApplication schema when reviewing or comparing tools - Validate all schema with Google Rich Results Test before deployment ### Content Management Systems (WordPress, Headless CMS) - Configure SEO plugins (Yoast, Rank Math, All in One SEO) for title and meta fields - Use canonical URLs to prevent duplicate content issues - Ensure XML sitemaps are generated and submitted to Google Search Console - Optimize permalink structure to use clean, keyword-rich URL slugs - Implement breadcrumb navigation for improved crawlability and UX ### Analytics and Monitoring (Google Search Console, GA4) - Track keyword ranking positions and click-through rates in Search Console - Monitor Core Web Vitals and page experience signals - Set up custom events in GA4 for CTA clicks and conversion tracking - Use Search Console Coverage report to identify indexing issues - Analyze query reports to discover new keyword opportunities and content gaps ## Red Flags When Performing SEO Optimization - **Keyword stuffing**: Forcing the target keyword into every sentence destroys readability and triggers search engine penalties - **Ignoring search intent**: Producing informational content for a transactional query (or vice versa) causes high bounce rates and poor rankings - **Duplicate or cannibalized content**: Multiple pages targeting the same keyword compete against each other and dilute authority - **Generic filler text**: Vague, unsupported statements add word count but no value; search engines and users both penalize thin content - **Missing schema markup**: Failing to implement structured data forfeits rich result opportunities that competitors will capture - **Neglecting internal linking**: Orphaned pages without internal links are harder for crawlers to discover and pass no authority - **Over-optimized anchor text**: Using exact-match anchor text excessively in internal or external links appears manipulative to search engines - **No performance tracking**: Publishing without KPIs or monitoring makes it impossible to measure ROI or identify needed improvements ## Output (TODO Only) Write all proposed SEO optimizations and any code snippets to `TODO_seo-optimization.md` only.
