1 — What is SEO? How search engines work (quick)

Search Engine Optimization (SEO) is the practice of making your website and content more discoverable in search engines (Google, Bing, etc.) so that relevant users find you when they search.

Search engines do three main things:

  1. Crawl — discover pages (links, sitemaps).
  2. Index — store and organize content.
  3. Rank — decide which pages to show for which queries.

If you want a reliable practical starting point, follow Google’s official SEO Starter Guide — it covers the fundamentals for webmasters. Google for Developers

2 — SEO glossary (must-know terms)

3 — SEO foundations (Beginner) — initial setup & quick wins

Goal: make search engines able to find, understand, and trust your site.

Initial checklist (day 0–7):

Quick wins:

  • Fix missing title tags and meta descriptions.
  • Use descriptive image alt attributes.
  • Remove or redirect thin/duplicate pages.
  • Improve internal linking to your best pages.

4 — Keyword research — step-by-step (practical)

Objective: find queries people actually search that you can realistically rank for.

Step 1 — Seed & brain dump

  • List core topics and seed keywords (3–10).
  • Ask: what problems do users have? What words would they type?

Step 2 — Tools

  • Use one or more: Google Autocomplete, Google “People also ask”, Keyword Planner, Ahrefs, SEMrush, AnswerThePublic, UberSuggest.
  • Export results to a spreadsheet.

Step 3 — Filter by intent

  • Map each keyword to user intent: Informational, Navigational, Transactional, Commercial Investigation.
  • Prioritize intent that matches the page type.

Step 4 — Volume vs difficulty

  • Add search volume and keyword difficulty/competition.
  • Use long-tail keywords (lower volume, higher conversion).

Step 5 — Keyword mapping

  • Create a keyword map: match primary + secondary keywords to specific pages.
  • Avoid keyword cannibalization — one keyword → one page ideally.

Suggested spreadsheet columns
Keyword | Search Intent | Monthly Volume | KD/Comp | Current Rank | Target Page URL | Notes/Opportunities | Content Type

Example mapping

  • Keyword: “best vegetarian fertility diet” → Blog post.
  • Keyword: “IVF clinic near me” → Local landing page with schema & NAP.

5 — On-page SEO — content that ranks

Goal: make each page clearly targeted and valuable for a single topic.

On-page checklist (page template):

  1. Title tag (≤ 60 chars): primary keyword near front, & brand if space.
  2. Meta description (120–160 chars): persuasive, includes keyword; not a ranking factor but improves CTR.
  3. URL slug: short, readable, includes main keyword.
  4. H1: unique, matches intent.
  5. Headings (H2/H3): use for structure and include LSI/secondary keywords.
  6. Intro (first 100–150 words): answer the user’s query quickly.
  7. Body: cover subtopics, use lists, images, tables; aim for usefulness vs length.
  8. Images: descriptive filenames + alt text + compressed.
  9. Schema: article, product, FAQ, recipe, localBusiness as appropriate.
  10. Internal links: 3–5 internal links to relevant pages.
  11. Outbound links: 1–3 references to authoritative sources.
  12. CTA: conversion element (form, phone, add to cart).
  13. Canonical tag: avoid duplicate-content issues.

Content writing tips

  • Write for users first — satisfy search intent fully.
  • Use natural language; diversify vocabulary (semantic SEO).
  • Use images, charts, examples, step-by-step instructions.
  • Add an FAQ section to capture featured snippets.
  • Update and repurpose top content periodically.

Meta example

6 — Technical SEO — backend fundamentals

Goal: remove barriers to crawling, indexing, and rendering.

Technical checklist (practical):

  • Robots.txt: ensure you’re not accidentally blocking important pages.
  • XML sitemap: include canonical URLs, keep updated, submit to GSC.
  • Status codes: fix 4xx and 5xx errors; ensure proper 301s for moved content.
  • Canonical tags: single preferred URL per content.
  • Pagination: rel=”next/prev” not required but handle canonicalization and filters.
  • Hreflang: for multilingual sites — correct tags and sitemap entries.
  • Structured data: add schema for rich results (Article, Product, BreadcrumbList, LocalBusiness).
  • Server & hosting: ensure fast, reliable hosting; use caching and CDN.
  • AMP: optional; most use good responsive design and Core Web Vitals improvements instead.
  • Robots meta tags: use noindex carefully for duplicates or staging pages.

Crawl budget & log analysis (advanced)

  • For big sites (>10k pages), analyze server logs to see crawler behavior.
  • Identify orphan pages, low-value pages consuming crawl budget, and fix internal linking.

7 — Core Web Vitals & Page Experience (must read)

Google measures real-world loading and interactivity through Core Web Vitals — a set of user-focused metrics (Largest Contentful Paint, Interaction to Next Paint (INP), and Cumulative Layout Shift). Improving these helps both user experience and search performance; Google recommends optimizing them for success with Search. Google for Developers+1

Note (metric change): the web platform introduced INP to replace FID for responsiveness — important when measuring interactivity. Google for Developers

Core metrics (basics):

  • LCP (Largest Contentful Paint) — loading speed of main content. Aim: ≤ 2.5s.
  • INP (Interaction to Next Paint) — responsiveness (replaces FID). Aim: good experience (lower value, monitor via field data).
  • CLS (Cumulative Layout Shift) — visual stability. Aim: ≤ 0.1.

How to improve

  • Optimize images (next-gen formats, lazy loading, proper dimensions).
  • Use critical CSS and defer non-critical CSS/JS.
  • Preload important fonts and resources.
  • Reduce main-thread work; split long tasks.
  • Use CDN, compress assets, and server caching.

Tools

  • Google Search Console Core Web Vitals report. Google Help
  • PageSpeed Insights, Lighthouse, WebPageTest.

8 — Content strategy, clusters & E-E-A-T (quality matters)

E-E-A-T stands for Experience, Expertise, Authoritativeness, Trustworthiness — an updated framework Google uses in quality evaluations; it’s hugely important for content, especially YMYL topics (Your Money/Your Life). Demonstrate author credentials, cite sources, and build reputation. Google for Developers

Content cluster model (recommended)

  • Pillar page: broad, high-level content covering a core topic.
  • Cluster pages: focused subtopic posts that link back to the pillar.
  • Use internal linking to signal topical authority.

Content brief template

  • Title / working title
  • Target keyword (+ synonyms)
  • Search intent & target audience
  • Word count range (based on competitor analysis)
  • Required sections / H2s / H3s
  • Internal links to include
  • External references / sources
  • CTA & conversion goal
  • Author byline + credentials (for E-E-A-T)

Editorial process

  1. Research & competitor analysis.
  2. Write draft — answer the query clearly.
  3. Add visuals, data, schema.
  4. Edit → SEO optimize (title, headings, meta).
  5. Publish + promote.
  6. Measure and update after 30/90 days.

9 — Off-page SEO & link-building (ethical)

Principle: high-quality, relevant links pass authority. Avoid spammy schemes.

Tactics that work

  • Content marketing & PR: create linkable assets (studies, original data, tools).
  • Guest posting on reputable sites (focus on relevance, not just link).
  • Broken-link building: find broken resources and offer your content as a replacement.
  • Skyscraper outreach: improve a top resource and reach out to sites linking to it.
  • Partnerships & sponsorships (be careful with nofollow/sponsored attributes).
  • Digital PR: pitch stories that journalists will cite and link to.

Link quality filters

  • Relevance to topic.
  • Authority / domain rating.
  • Natural anchor text diversity.
  • Link placement (in content > footer).
  • Traffic → do links from pages that actually get visitors.

Toxic links

  • Ignore cheap link farms, private blog networks (PBNs), or automated link schemes — can cause penalties.

10 — Local SEO (small business + multi-location)

Priority: consistent Name, Address, Phone (NAP) and an optimized Google Business Profile.

Checklist

  • Claim and verify Google Business Profile.
  • Add complete business info: categories, hours, photos, services.
  • Encourage reviews and respond professionally.
  • Local schema (LocalBusiness) markup.
  • Build consistent citations across directories (Name, Address, Phone exact match).
  • Create location pages for multi-location businesses (unique content per location).
  • Local link building: local directories, local press, community sponsorships.

11 — eCommerce SEO specifics

Key issues to handle:

  • Faceted navigation — block or canonicalize filter URLs to avoid crawl explosion.
  • Product schema — price, availability, aggregateRating, offers.
  • Unique product descriptions — avoid manufacturer duplicates.
  • Customer reviews — schema and visible reviews (social proof).
  • Pagination & infinite scroll — handle canonical and indexing properly.
  • Inventory & out-of-stock handling — use structured data & UI signals.

12 — Analytics & measurement (GA4 + Search Console)

Why measure: SEO is iterative — you must know what works.

Essential tracking

  • Google Search Console (GSC): impressions, clicks, average position, index coverage, sitemaps, Core Web Vitals.
  • Google Analytics 4 (GA4): events, conversions, user journeys. Note: Universal Analytics stopped processing data (July 1, 2023) — GA4 is the default analytics platform now. Google Help

KPIs to track

  • Organic sessions (by landing page).
  • Impressions & CTR (Search Console).
  • Average ranking position for target keywords.
  • Conversions from organic (goals/ecommerce).
  • Bounce rate / engagement metrics (GA4 uses engagement metrics differently).
  • Pagespeed / Core Web Vitals distribution.

GA4 tips

  • Define events & conversions (e.g., form_submit, purchase).
  • Link GA4 with GSC for combined reporting.
  • Use UTM parameters for inbound campaigns to track sources.

Pre-migration (2–4 weeks before)

  • Audit current URLs & top traffic pages.
  • Build a complete redirect map (old → new).
  • Back up content & analytics data (export GA/UA historical if needed).
  • Test new site on staging (robots noindex on staging).

Migration day
