Search engines now lean on hundreds of signals, but the nine factors below dominate visibility today. Each combines long-standing fundamentals with 2024-25 algorithm changes.
1. Helpful, People-First Content + E-E-A-T
Google’s “Helpful Content” system, baked into the core ranking pipeline, rewards pages that genuinely solve a query and demonstrate Experience, Expertise, Authoritativeness & Trustworthiness (E-E-A-T). Google’s own guidelines urge creators to self-audit against those pillars.
Action points
- Publish from real practitioners (show bios, credentials, first-hand data).
- Provide original research, screenshots, or test results—material a language model can’t hallucinate.
- Keep YMYL topics (health, finance, safety) doubly referenced and fact-checked.
2. Search Intent & Behaviour Signals (NavBoost)
Leaked documentation confirms Google re-orders results with click-stream data via the NavBoost system. High pogo-stick rates, short dwell time or low CTR can sink a page even if it is “technically” optimised.
Action points
- Audit the live SERP before writing—match its dominant format (video, listicle, product grid).
- Place the answer or product USP above the fold; use jump-to links or an on-page table of contents.
- Improve micro-UX: intuitive headings, readable line length, fast interactive elements.
3. Domain Authority & Backlinks
Quantity matters far less than context: links from niche-relevant, high-trust sites correlate strongly with top positions, while manipulative patterns trigger manual actions or algorithmic discounting
Action points
- Earn links via original studies, data visualisations, and digital PR instead of bulk purchases.
- Monitor toxic links and disavow them quarterly.
- Track brand mentions without links—Google increasingly treats them as partial authority signals.
4. Page Experience & Core Web Vitals (LCP, CLS, INP)
Interaction to Next Paint (INP) replaced FID in March 2024, measuring true interface responsiveness. Pages outside the “good” thresholds increasingly drop in mobile results.
| Metric | Target |
|---|---|
| Largest Contentful Paint (LCP) | < 2.5 s |
| Cumulative Layout Shift (CLS) | < 0.1 |
| Interaction to Next Paint (INP) | < 200 ms |
Action points
- Serve images in AVIF/WebP, defer non-critical JavaScript, and stream critical CSS inline.
- Use priority hints (
<link rel=preload>) for hero media and fonts.
5. Mobile-First & Technical Hygiene
Google completed its mobile-first index migration in Oct 2023, so the smartphone crawler is canonical. HTTPS, canonical tags, XML sitemaps and minimal 4xx/5xx errors remain baseline trust signals.
6. Structured Data & Machine Readability
Schema.org markup feeds knowledge graphs, rich snippets and, crucially, generative answer engines that “quote” trustworthy sources. Sites using comprehensive, valid JSON-LD see higher rich-result CTR and better entity understanding.
Action points
- Mark up FAQs, HowTo, Product, and Review entities; validate in Search Console’s Rich Results test.
- Embed clear publisher microdata (
Organization,Author) to reinforce E-E-A-T.
7. Optimising for Generative Answer Engines
Google AI Overviews and Yandex Neuro lift passages directly into LLM summaries. They favour concise, fact-dense paragraphs, lists, and tables with explicit attribution.
Action points
- Use question-answer blocks, checklists, TL;DR boxes.
- Keep facts current and cite primary sources; inconsistent data risks hallucinated summaries.
- Track not just clicks but appearance frequency in overviews.
8. Local & Semantic Signals
For brick-and-mortar and service-area businesses, a complete Google Business Profile (NAP accuracy, reviews, fresh photos) plus location-oriented schema strongly influences the “local pack.”
9. Freshness & Core Updates
The March 2025 Core Update (13 – 27 Mar) showed Google’s ongoing fight against thin AI-generated pages and duplicate content. Expect quarterly core refreshes that reassess site-wide quality.
