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 couple are freemium (a genuinely useful free tier, with paid plans for scale) and are flagged honestly.

If you only set up the minimal stack you'll be fine. This page is the fuller directory: what each tool is, when to reach for it, and what the free tier really gives you.

See how engines see you#

These two 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.

Setup and the reports worth living in are covered in Your SEO Toolkit and Crawling & Indexing.

Bing Webmaster Tools#

Free, and underrated. The same idea as Search Console, for Bing's index. It takes one click to import your GSC data, so there's no excuse to skip it. Bonus: Bing's index feeds ChatGPT search, which makes this quietly relevant to GEO.

  • Use it for: Bing/ChatGPT visibility, a free second opinion on keywords, and built-in site-scan tooling.

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. It's not the friendliest interface in the world, but it's free, ubiquitous, and the metrics that matter for SEO are spelled out in Analytics & Forecasting.

  • Use it for: traffic and conversion measurement, channel attribution, audience insight.

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.

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 Knowledge Panel, your spot in the map pack, reviews, hours, and photos. For local search, a fully completed profile often outperforms months of other work.

  • 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 ranking) for any URL. Treat the lab score as a to-do list and the field data as the verdict.

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

Fixing what it flags 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.

Free. Relative search interest over time. It won't give you absolute volume, but it's unbeatable for spotting seasonality, comparing two terms head-to-head, catching rising topics early, and validating whether a trend is real or already cooling.

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

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 handed to you for free.

  • Use it for: question research, content structure, and capturing PAA real estate.
  • Free tier: a handful of searches per month, which is plenty for planning individual articles. Paid plans add volume and exports.

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 still lets you run a limited number of lookups per day, which is enough to size up a keyword or peek at a competitor.

  • Use it for: competitive research, keyword difficulty, backlink gap analysis.
  • Free tier: free account with a small daily query cap. (Ahrefs Webmaster Tools is a free alternative for auditing your own site.) See Competitor Analysis.
