Quick overview

SEO is ongoing. Implement, measure, and iterate. Below the checklist is grouped into foundation, technical, on-page, content, off-page and local SEO for easier execution.

1. Foundation (must-do)

• Install Google Analytics 4 — track users, events & conversions.
• Set up Google Search Console — monitor index status, errors, and search queries.
• Submit an XML sitemap and verify it in Search Console.
• Create / upload robots.txt to control crawling.
• Choose and enforce a preferred domain (www vs non-www) and HTTPS.

2. Technical SEO

• Ensure mobile-friendliness — responsive design and mobile tests.
• Enable HTTPS (SSL) site-wide.
• Improve site speed — measure with PageSpeed Insights and Lighthouse.
• Fix broken links (404s) and remove dead pages or redirect appropriately.
• Eliminate redirect chains (use single 301 redirects).
• Enable lazy loading for below-fold images and heavy assets.
• Implement structured data (Schema) for articles, products, FAQs and breadcrumbs.
• Optimize Core Web Vitals — LCP, CLS, FID / INP.
• Use a CDN to serve assets faster worldwide.
• Check crawlability — no accidental noindex or blocked resources.

3. On-Page SEO

• Do proper keyword research — focus on intent and volume.
• Include the target keyword in the Title tag (keep titles ≤60 chars).
• Write compelling meta descriptions that include the target keyword and a CTA.
• Use a single H1 and meaningful H2/H3 subheads for structure.
• Place target keyword in the first 100 words naturally.
• Add internal links to related pages to pass link equity.
• Link to credible external sources where relevant.
• Use clean URLs — short, keyword-rich slugs (avoid query strings).
• Write descriptive alt text for all images.
• Optimize images (WebP, proper sizes) and provide width/height attributes.
• Add FAQ sections and tag them with FAQ schema where applicable.
• Keep content readable — short paragraphs, bullets, and plain language.

4. Content Optimization

• Publish high-quality, original content that solves user problems.
• Refresh and update old posts to keep them evergreen.
• Create long-form content when the topic demands — 1,500–3,000+ words for in-depth guides.
• Build EEAT — show Expertise, Experience, Authoritativeness, Trustworthiness.
• Add multimedia — images, infographics, and video to increase engagement.
• Match search intent exactly (informational, transactional, navigational).
• Avoid keyword stuffing — write naturally and prioritize users.

5. Off-Page SEO & Promotion

• Build high-quality backlinks via guest posts, partnerships, and outreach.
• Promote content on social platforms to build traffic and shares.
• Use niche directories when they add value (avoid spammy lists).
• Encourage branded searches — brand awareness helps organic ranking.
• Collect reviews if you have a local business (Google Reviews, industry sites).

6. Local SEO (if you’re local)

• Optimize your Google Business Profile — accurate NAP, categories, photos, services, hours.
• Ensure consistent NAP across citations (Name, Address, Phone).
• Use local schema and location pages if you serve multiple areas.

Final notes & quick wins

Start with the fundamentals: analytics, Search Console, sitemap, mobile, speed, and title tags. Then tackle technical fixes and content improvements in sprints.

Quick wins: fix title/meta tags on your top 10 pages, compress images, remove one redirect chain, and add 3 internal links from top-performing posts to pages you want to rank.
