SEO checklist: 16 steps to rank higher in organic search

Executive overview

Most SEO efforts fail because they skip fundamentals: unindexable pages, thin content, and link gaps that make ranking impossible. This checklist works through site health, content quality, and link building in sequence.

Fix crawlability and indexability first — nothing else matters if Google can't reach your pages. Then address content gaps and low-hanging-fruit keywords before pursuing new links.

The biggest leverage point is often already-ranking keywords in positions 2–15, not new content.

Track the right KPIs

• Organic traffic growth — measure monthly, compare annually
• Total organic keywords — track via SEMrush organic research
• Referring root domains — monitor growth monthly, quarterly, and annually

Fix crawlability and indexability

• Use SEMrush Site Audit → Issues → filter by Crawlability, then Indexability
• Check robots.txt and noindex tags for unintended blocks
• Pages not indexed cannot rank — fix these before anything else

Pass core web vitals

• Google confirmed core web vitals as a ranking factor
• Use SEMrush Site Audit overview for the CWV score and problem pages
• Most fixes apply site-wide, not page by page

Optimise site architecture

• No page should be more than three clicks deep
• Find deep pages in SEMrush: Crawled Pages → More Filters → Crawl Depth → 4+ clicks
• Low internal link rank (ILR) scores signal pages lacking internal link equity
• Prioritise adding internal links to pages that already have backlinks — they pass authority

Target low-hanging-fruit keywords

• Filter organic keywords to positions 2–15 in SEMrush
• These need minor optimisation or a few backlinks to move to position 1
• Moving from position 5 to position 1 can triple or quadruple click volume (31% vs 9% CTR)

Fix content targeting issues

• Clustering: pages outside the top 50 often lack a dedicated, targeted URL — create one
• Keyword cannibalization: two pages targeting the same keyword split authority and confuse Google
• Use SEMrush Position Tracking → Cannibalization tab to surface conflicts
• Fewer, stronger pages outperform many weak ones

Evaluate and optimise existing content

• Before on-page SEO, ask: is this page genuinely different from what ranks?
• Me-too content may get short-term gains; unique angles produce durable rankings
• Minimum on-page basics: primary keyword in URL, title, H1, first sentence, last sentence
• Use SEMrush On-Page SEO Checker for strategy, semantic, technical, and UX recommendations
• Build topical authority with supporting cluster content; use alsoask.com for People Also Ask ideas

Build links that actually work

• Best long-term method: create linkable assets — content people link to without being asked
• Proven linkable formats: comprehensive guides, audit frameworks, deep reference content
• Find competitor top linked pages via SEMrush Backlink Analytics → Top Pages for link topic ideas
• Use the relevancy pyramid: start with closely relevant link sources, expand outward as needed
• High-quality backlink checklist:
  1. Relevance to your niche
  2. Organic traffic on the linking domain
  3. Domain authority
  4. Clean backlink profile (check in SEMrush)
  5. Editorial difficulty — harder to get = more valuable

Close the authority gap

• Use SEMrush Backlink Gap tool to compare referring domain counts against competitors
• Fix the domain-level gap first, then the page-level gap for target keywords
• For each target keyword, benchmark average referring domains of top 10 SERP results and match that number
