Journey fit
Spans multiple journey phases - primary shelf plus alternate fits below.
Launch / seo is the canonical home for pre-publish and post-publish page audits that drive organic discovery, separate from backend build or ship security gates. On-page SEO fits the seo subphase: keyword placement, meta, H-structure, internal links, and technical on-page elements rather than ASO or paid distribution.
Where it fits
Score a new best-of roundup URL for head terms before requesting indexing.
Re-audit after expanding word count and adding internal links to brand pages.
Check title and meta on a smoke-test landing page before paid campaigns.
How it compares
On-page checker with weighted scores—not a replacement for Search Console trends or server-side log analysis.

Add links to individual headphone review pages (/sony-wh1000xm5-review, /bose-qc-ultra-review) and the headphones category page. Target 5-8 contextual internal links. 2. **3 product images missing alt text** — Images for Sony WH-1000XM5, Bose QC Ultra, and Apple AirPods Max have empty alt attributes. Each missing alt tag is a lost ranking signal in Google Images. ### Important 1. **Meta description lacks call-to-action** — Current description states facts but does not compel clicks. Add "Compare prices and features" or "See our top picks" to drive CTR. ## Quick Wins 1. **Add alt text to 3 images** (5 min) — Use descriptive text like "Sony WH-1000XM5 noise cancelling headphones on desk" instead of empty attributes. 2. **Rewrite meta description with CTA** (5 min) — Change to: "Compare the 10 best noise cancelling headphones for 2025. Expert-tested picks from Sony, Bose, and Apple with pros, cons, and pricing. See our top picks." 3. **Add 4+ internal links** (10 min) — Link product names to their individual review pages and add a "See all headphones" link to the category hub. ``` --- ## Audit Checklists by Page Type ### Blog Post Checklist ```markdown - [ ] Title includes keyword and is compelling - [ ] Meta description has keyword and CTA - [ ] Single H1 with keyword - [ ] H2s cover main topics - [ ] Keyword in first 100 words - [ ] 1,500+ words for competitive topics - [ ] 3+ internal links with varied anchors - [ ] Images with descriptive alt text - [ ] FAQ section with schema - [ ] Author bio with credentials ``` ### Product Page Checklist ```markdown - [ ] Product name in title - [ ] Price and availability in description - [ ] H1 is product name - [ ] Product features in H2s - [ ] Multiple product images with alt text - [ ] Customer reviews visible - [ ] Product schema implemented - [ ] Related products linked - [ ] Clear CTA button ``` ### Landing Page Checklist ```markdown - [ ] Keyword-optimized title - [ ] Benefit-focused meta description - [ ] Clear H1 value proposition
