Intermediate Guide: Fix Poor Mobile SEO Performance for Startup SEO Specialists Who Are Watching Mobile Traffic Underperform Desktop Using ChatGPT

You are a senior mobile SEO strategist with 10 years of experience building keyword research frameworks and content briefs that close the gap between desktop and mobile search performance for startup companies where mobile traffic represents the majority of organic sessions but converts at a fraction of the desktop rate. Help me write an SEO content brief so I can increase share of voice in search and build a content strategy that captures mobile search intent rather than producing desktop-optimized content that underperforms in the channel where most traffic actually arrives. My situation: - Startup product and target audience: [e.g., "a B2C meal planning app targeting busy parents aged 28 to 42 who search primarily on mobile during commute and school pickup times"] - Mobile versus desktop performance gap: [e.g., "mobile represents 74% of organic sessions but converts at 1.2% versus 4.8% on desktop — mobile sessions also show 67% bounce rate versus 41% on desktop"] - Competitor keyword research findings: [e.g., "three competitors ranking above us for 'quick weeknight dinner ideas' have mobile-optimized content with short paragraphs, jump links, and a recipe card at the top — our equivalent post buries the recipe after 800 words of introduction"] - Target keyword and mobile search intent: [e.g., "'easy family dinner recipes under 30 minutes' — 18,000 monthly searches, 68% mobile, intent is immediate recipe access not research"] - Current content brief format: [e.g., "word count target, keyword list, and H2 suggestions — no mobile formatting requirements, no guidance on paragraph length or answer placement for mobile readers"] - Current ranking position for the target keyword: [e.g., "position 14 for the target keyword on desktop, position 22 on mobile — Google Search Console shows 3.1% CTR on desktop versus 0.8% on mobile despite similar impression volumes"] - Content team size and brief turnaround: [e.g., "one freelance writer producing two posts per week — brief must be usable without a follow-up briefing call"] Deliver: 1. An SEO content brief structured for mobile-first performance — specifying the target keyword, search intent classification (navigational, informational, or transactional), the answer placement requirement (the primary answer or recipe must appear within the first 200 words), paragraph length maximum (three sentences per paragraph), and H2 heading format requirements for mobile scanners 2. A competitor keyword gap analysis format — a table structure showing the top five ranking competitors for the target keyword, their estimated word count, their answer placement position (how many words before the primary content), their mobile-specific formatting features, and the one structural element each competitor uses that the current content does not 3. A mobile search intent content structure for recipe and how-to content — a seven-section template covering a one-sentence answer, an ingredient or materials list at the top, step-by-step instructions in a numbered format with a maximum of 15 words per step, a FAQ section placed above the fold on mobile, and a jump link table of contents visible within the first screen 4. A meta title and description brief for mobile SERP display — the meta title formatted for the 50-character mobile truncation limit rather than the 60-character desktop limit, the meta description with the primary benefit in the first 80 characters before mobile truncation, and a structured data recommendation for recipe or how-to schema that enables rich results on mobile 5. A mobile bounce rate reduction specification — three specific content formatting requirements the writer must apply throughout the post, covering sentence length maximum (under 20 words), image placement frequency (one image per 200 words), and CTA placement (above the fold on mobile using a sticky element or a prominent jump link) 6. A share of voice keyword cluster brief — the primary keyword, four related keywords with lower competition that share the same mobile search intent, and a content prioritization matrix that ranks the five keywords by mobile search volume, current ranking position, and estimated traffic opportunity 7. A content brief quality checklist — eight criteria the SEO specialist applies to the brief before sending to the writer, covering mobile intent alignment, answer placement specification, paragraph length guideline, schema recommendation, internal link targets with anchor text, and the one competitor structural element that must be replicated or improved 8. A 30-day mobile performance tracking brief — the three Google Search Console metrics to compare between mobile and desktop weekly (CTR, average position, and click volume), with the threshold that triggers a content update versus a technical mobile optimization review **Write every brief component assuming the freelance writer is a strong writer with no SEO training and no awareness of mobile-specific optimization requirements — every specification must be prescriptive enough that a writer following the brief produces mobile-optimized content without needing to understand why each requirement exists.**
