Index coverage, Core Web Vitals field data, query performance

"The single most honest feedback loop between a site and Google. I check it every morning without exception."

Organic traffic, conversions, user behaviour attribution

"Not perfect, but irreplaceable for tying search visibility to actual business outcomes."

Keyword research, competitor gaps, backlink audit, site crawl, AI Overviews tracking

"My primary all-in-one platform. The Site Audit module catches structural issues that lighter tools miss entirely."

Backlink analysis, content gap, rank tracker, site audit

"The strongest backlink index in the market. I cross-reference with Semrush — the overlap surprises clients every time."

Full-site crawl, redirect chains, duplicate content, schema extraction

"The industry-standard crawler. If Googlebot wouldn't like it, Screaming Frog will find it. I run it on every audit, no exceptions."

Visual crawl audits, actionable recommendations, rendering analysis

"Where Screaming Frog gives raw data, Sitebulb gives prioritised findings. I use both — they catch different things."

Official Google documentation for indexing, crawling, structured data, and ranking

"Primary source. If it's not written here, it's speculation — including most takes on SEO Twitter."

Structured data validation for Google-eligible rich results

"Schema.org compliance and Google eligibility are two different things. This tool tests the one that actually matters for SERPs."

Schema.org specification validation

"The spec-level validator. I run it alongside Google's Rich Results Test — together they cover both compliance layers."

SEO dashboards, client reporting, cross-tool data visualisation

"My reporting layer. I connect GSC + GA4 + Semrush into a single dashboard every client can read without a spreadsheet."

WordPress on-page SEO, schema management, sitemap generation

"The cleanest schema control layer for WordPress. I use it as the single schema source of truth on every WordPress build."

AI citation tracking across ChatGPT, Gemini, Perplexity, AI Overviews, Copilot

"My primary GEO monitoring platform. The Prompt Planner surfaces which questions your brand should be answering — and isn't."

Brand monitoring + GEO audit across major AI engines

"The most accessible entry point into AI visibility auditing. The GEO audit converts findings into prioritised actions, not just charts."

Prompt-level AI visibility tracking, prompt volume estimation, competitor benchmarking

"Prompt volume estimation using clickstream data is a genuine differentiator — finally a way to prioritise which queries to target in AI answers."

AI visibility audit + content generation to close citation gaps

"Useful when a client needs both monitoring and execution. The AI agents draft content specifically to improve citation rates."

Citation-first AI search engine, brand visibility testing

"The purest citation engine in AI search. If a brand appears here, it's genuinely trusted. I use it manually to test client visibility."

Answer engine testing, brand mention audits, content reasoning

"I regularly test how clients' brands appear in ChatGPT answers. It's its own visibility layer now — and most brands have no idea what it says about them."

AI Overview behaviour testing, Google-native generative search

"Essential for AIO work. Gemini's outputs feed directly into Google's AI Overviews — if you're not testing here, you're optimising blind."

Deep reasoning, long-document analysis, content strategy, brand audit testing

"My preferred LLM for reasoning through complex SEO problems. Also increasingly relevant as a search surface in its own right."

Bing-powered AI search testing, citation behaviour in Microsoft ecosystem

"Copilot pulls from Bing, which has a different index and citation logic than Google. Worth auditing separately for any brand with B2B exposure."

CrUX field data, Lighthouse lab data, LCP / CLS / INP scoring

"The authoritative source of real-world CWV data from actual users. Field data beats lab data every time — this has both."

Performance, accessibility, best practices, and SEO audit in one run

"Runs inside DevTools or CI pipelines. I use it on every page template before pushing any change to production."

Waterfall analysis, load time breakdown, render timeline

"The waterfall view shows what loads in what order. When LCP is slow, GTmetrix usually tells me exactly why in thirty seconds."

Advanced performance testing, filmstrip view, multi-location real-browser tests

"For deep performance investigation. The filmstrip view showing how the page renders frame-by-frame is invaluable for CLS debugging."

Performance profiling, network analysis, DOM inspection, LCP/CLS/INP debugging

"The most powerful free tool in any technical SEO's kit. I live in the Performance and Network tabs during audits."

Primary testing browser, extension ecosystem, DevTools host

"Still the browser closest to Chromium-based crawlers. What it renders, search engines likely render."

Privacy-first browsing, unpersonalised SERP research

"I use Brave for research sessions where I don't want personalised results polluting competitive SERP analysis."

Mobile usability validation from Google's perspective

"Google uses mobile-first indexing. If it fails here, it's not just a UX problem — it's an indexing problem."

Live Googlebot rendering, index status, crawl request

"The only way to see exactly what Googlebot rendered on a specific URL. I use it to verify JS-heavy pages are rendering correctly."

Primary editor for scripts, schema JSON-LD, config files, client spec docs

"Fast, extensible, and the closest thing to a universal standard. My most-used app after a browser."

Terminal-based editing, quick server-side fixes, SSH sessions

"Once you learn it, you never go back. I use it for any edit that happens inside a server session."

Terminal multiplexer, persistent sessions, multi-pane audit workflows

"Long audit scripts and crawls run in Tmux sessions that survive disconnects. Saved hours of re-running jobs."

Development OS, server environment parity, scripting and automation

"Most SEO infrastructure runs on Linux. Running it locally means no "works on my machine" surprises when scripts hit production."

Version control, script storage, client implementation spec docs

"Everything I write that lives in code goes into a repo. Client teams can review, implement, and reference it months later."

Crawl scripts, log file analysis, data processing, GSC API automation

"My scripting language for anything that needs to run at scale — log parsing, bulk schema generation, API data pulls."

Content scoring, NLP-based optimisation, SERP analysis for content briefs

"Useful for content briefs on competitive queries. The correlation data speeds up the "what does this page need to cover" question significantly."

Content grading, topic coverage, semantic SEO recommendations

"My preferred content optimisation tool for clients with in-house writing teams. The grade system gives writers a clear target without SEO jargon."

AI-assisted content briefs, SERP research synthesis, answer intent analysis

"Particularly useful for building briefs that cover questions AI engines are likely to pull answers from."

Content drafting, headline testing, tone refinement, FAQ generation

"A first-draft accelerator, not a replacement for strategy. I use it to move faster — never to think less."

Long-form reasoning, document analysis, content strategy, structured writing

"For anything that requires sustained reasoning over long context. Writing a 4,000-word technical guide starts here."

Google-native content testing, AI Overview eligibility checking

"I test draft content in Gemini to see whether it gets cited in AI answers before publishing. It's become a pre-publish QA step."

Clicks, impressions, CTR, position, index coverage

"First-party data directly from Google. No paid tool can replicate this — they all estimate what GSC measures directly."

Session-level attribution, goal tracking, organic channel analysis

"The bridge between search performance and business outcomes. I set up custom organic segments on every account."

Unified dashboards connecting GSC, GA4, Semrush, and client KPIs

"My client reporting layer. A well-built Looker Studio report replaces three separate tool logins."

Rank tracking, visibility trends, competitor benchmarking

"I use the Position Tracking module for weekly rank reports and the Sensor feature to detect algorithm volatility before clients notice it."

Session recordings, heatmaps, rage clicks, scroll depth

"Free and surprisingly powerful for behavioural analysis. I use it to diagnose pages with high organic traffic but low conversion."

Authoritative documentation for everything Google indexes

"The canonical source. I read every update, every guideline change, every new structured data type the moment it drops."

HTML, CSS, JavaScript, Web APIs specification reference

"The authoritative spec for everything that runs in a browser. Bookmarked permanently. Wikipedia for the web platform."

Structured data vocabulary, property definitions, type hierarchy

"The source of truth for every schema type I implement. I read the actual spec rather than relying on tutorials."

Core Web Vitals documentation, web performance best practices

"Google's own guidance on building fast, accessible pages. The CWV deep-dives here are better than most paid courses."

Quick capture, ideas mid-audit, checklists, labelled research notes

"Ruthlessly simple. I capture insights the moment they appear and tag them for later — before context disappears."

CRM, client pipeline, lead tracking, deal management

"I track every lead and client relationship here. Keeps the business side clean so I can focus entirely on the work."

Meeting scheduling, discovery call booking

"Eliminates the back-and-forth on scheduling. Discovery calls, check-ins, and client onboarding all flow through this."

Project docs, audit templates, content briefs, SOPs

"My long-form workspace. Audit deliverables, sprint scopes, and client strategy docs all live here."

Personal knowledge base, linked notes, research vault

"Where my thinking compounds over time. SEO patterns I spot across audits get logged here — linked, not siloed."

Video walkthroughs, SEO tutorials, audit breakdowns

"Both a research tool and a publishing channel. I learn from the sharpest practitioners here and publish my own work in the same space."

Thought leadership, SEO and AI search insights, professional network, inbound leads

"Where I share observations from client work, publish takes on algorithm updates, and connect with the people actually building things."

Open scripts, audit tools, schema templates, public work

"Public-facing code. If something I built is useful to other SEOs, it lives here."

Personal site, long-form articles, services, SEO case studies

"My primary online presence — and a live test environment. Every SEO recommendation I give to clients I've already tested here."
