Free SEO & Marketing Tools

Here's the good news that the paid-tool ads won't tell you: you can run a complete, professional SEO and marketing operation for $0. The tools below are the ones that actually move the needle, grouped by the job they do. Most are fully free; a few are freemium (a genuinely useful free tier, with paid plans for scale) and are flagged honestly.

If you haven't yet, set up the minimum stack in ten minutes first: it walks through Search Console, Bing Webmaster Tools, GA4, a crawler and PageSpeed Insights step by step. This page is the broader catalogue: what each tool is, when to reach for it, and what the free tier really gives you. Limits and features were checked on 5 October 2026; free tiers change, so confirm before you plan around one.

See how engines see you#

These are the source of truth. Everything else estimates what these tell you directly.

Google Search Console#

Free. Google, telling you to your face how it sees your site: the queries you appear for, your clicks and impressions, what's indexed (and why the rest isn't), Core Web Vitals, and manual actions. If you install one tool, install this one.

Since 2025 it has gained a lot: a Generative AI performance report (impressions in AI Overviews and AI Mode, global since 31 August 2026), a branded / non-branded filter, chart annotations, weekly and monthly views, query groups, and the Insights report built into the main interface. In July 2026 it also added platform properties for your Instagram, TikTok, X and YouTube content.

• Use it for: real query data, indexing diagnostics, AI feature impressions, sitemap submission, catching penalties early.
• Link: search.google.com/search-console

Setup is in Your SEO Toolkit; the indexing reports are covered in Crawling & Indexing.

Bing Webmaster Tools#

Free, and underrated. The same idea as Search Console, for Bing's index, and it imports your Search Console sites in one click. Its AI Performance report (public preview since February 2026) is the standout: citations of your pages in Microsoft Copilot and Bing AI summaries, sampled grounding queries, and, since June 2026, intents, topics and citation share. That makes it a free, first-party window into AI visibility.

• Use it for: Bing and Copilot visibility, AI citation data, IndexNow submissions, and a free second opinion on keywords and site health.
• Link: bing.com/webmasters

Understand your visitors#

Search Console stops at the click. These tools pick up the story once someone lands.

Google Analytics 4#

Free. The default for understanding what happens after the click: sessions, conversions, traffic sources, and which content actually drives action. Since May 2026 it groups visits from ChatGPT, Gemini, Copilot and other listed assistants into a built-in AI Assistant channel. The metrics that matter for SEO are spelled out in Analytics & Forecasting.

• Use it for: traffic and conversion measurement, channel attribution (including AI assistants), audience insight.
• Link: analytics.google.com

Privacy-first alternatives such as Plausible, Fathom and Umami are lighter and simpler, but they are paid or self-hosted rather than free.

Microsoft Clarity#

Free, and genuinely delightful. Where GA4 tells you what happened, Clarity shows you why: heatmaps of where people click and scroll, plus session recordings of real visits. Watching a user rage-click a button that isn't a button teaches you more than any bounce-rate chart.

• Use it for: spotting UX friction, dead clicks, and where readers drop off, which feeds directly into Core Web Vitals and on-page improvements.
• Link: clarity.microsoft.com

Win the local map#

Google Business Profile#

Free, and the single highest-leverage tool for any business with a location or service area. It controls your business panel, your spot in the map pack, reviews, hours and photos, and it feeds Google's AI answers about local businesses. Google shut down the profile Q&A API in November 2025 and Q&A has been reported disappearing from profiles since, so ignore older advice to seed your own questions.

• Use it for: the map pack, "near me" queries, reviews, and local brand presence.
• Link: business.google.com

The full playbook is in Local SEO.

Measure speed#

Google PageSpeed Insights#

Free. Runs Lighthouse and shows your real-user Core Web Vitals (the field data Google actually uses) for any URL. Treat the lab score as a to-do list and the field data as the verdict. Since Lighthouse 13 (October 2025) the lab section is organised as "insights" (LCP breakdown, render-blocking requests, image delivery), so older tutorials that name audits like "Defer offscreen images" are out of date.

• Use it for: diagnosing LCP, INP and CLS problems with prioritized fixes.
• Link: pagespeed.web.dev

CrUX Vis#

Free. Google's view of Chrome UX Report history for an origin or URL, updated weekly. It replaces the Looker Studio CrUX Dashboard, which was shut down at the end of November 2025.

• Use it for: Core Web Vitals trends over months, before and after a release.
• Link: cruxvis.withgoogle.com

Fixing what these flag is the whole of Core Web Vitals.

Find what people actually want#

Research tools turn guesses into evidence. Start with the free ones; reach for freemium when you need scale.

Google Trends#

Free. Relative search interest over time. It won't give you absolute volume, but it's unbeatable for spotting seasonality, comparing terms head-to-head, catching rising topics early, and checking whether a trend is real or already cooling. A Trends API entered alpha with limited testers in July 2025.

• Use it for: seasonality planning, term comparison, breakout-topic detection.
• Link: trends.google.com

Google Keyword Planner#

Free with a Google Ads account (no spend required). Search volume ranges and keyword ideas straight from Google Ads data. Ranges are broad unless you run campaigns, but they are Google's own numbers.

• Use it for: rough volume sizing and seed keyword expansion in the research process.
• Link: ads.google.com/home/tools/keyword-planner

AlsoAsked#

Freemium. It maps the "People Also Ask" universe: the branching tree of follow-up questions real people ask around a topic. That tree is a content outline and an AEO goldmine.

• Use it for: question research, content structure, and capturing PAA real estate.
• Free tier: a few searches a day, which is plenty for planning individual articles. Paid plans add volume and exports.
• Link: alsoasked.com

Semrush#

Freemium. A full marketing suite: keyword research, keyword difficulty, competitor analysis, backlink data, and rank tracking. The paid tiers are powerful but pricey; the free account allows a small number of lookups per day (around 10 at the time of writing), enough to size up a keyword or peek at a competitor.

• Use it for: competitive research, keyword difficulty, backlink gap analysis. See Competitor Analysis.
• Link: semrush.com

Ahrefs Webmaster Tools#

Free for sites you verify. Site audits and backlink data for your own properties, using Ahrefs' crawler and link index. A good free complement to Search Console's links report.

• Link: ahrefs.com/webmaster-tools

Validate and preview#

• Rich Results Test (search.google.com/test/rich-results): checks markup against the rich results Google still supports. FAQ and HowTo are no longer among them. See Structured Data.
• Schema Markup Validator (validator.schema.org): general schema.org validation, independent of Google features.
• Rankyl's SERP preview (/tools/serp-preview): see how a title and meta description truncate at real pixel widths.
• Rankyl's AI crawler checker (/tools/ai-crawler-checker): paste a robots.txt and see which AI bots it allows. Background in AI Crawlers & Bot Access.
• Screaming Frog SEO Spider: free up to 500 URLs per crawl. Setup is in Your SEO Toolkit.
