Most site owners start with Google Analytics and never look at anything else. That is a fine start, but it leaves gaps: why people leave a page, whether pages load fast enough on a phone, and which search queries bring the visits in the first place. These five free tools cover those gaps, and none of them needs a credit card.
Quick Answer: For most sites, pair Google Analytics 4 (traffic and conversions) with Google Search Console (search queries and indexing). Add Microsoft Clarity when you need to see how visitors actually use a page, and run PageSpeed Insights on your key URLs. Cloudflare Web Analytics is a light option if your DNS already runs through Cloudflare.
What makes a tool worth keeping
Free tiers change, so the test I use is simple. A tool earns a place only if it answers a question you cannot answer from the others, and if its limits leave room for a real site. If you are new to the idea, why web analytics matters is a good primer before you start comparing dashboards. Older roundups still circulate, including an NBC News piece on tools for taking SEO further and a Fox News list of marketing tools. Many of the products they name have changed since, so read them as background. The five below pass that test as of October 2026. Check each vendor's pricing page before you commit, because limits and retention windows are the first things that change.
1. Google Analytics 4
Google Analytics 4 (GA4) is the successor to Universal Analytics, which stopped processing new data in July 2023. GA4 counts events rather than page views alone, so scrolls, file downloads, form submissions and purchases can all be tracked without extra code.
It is free for most sites and is the reference point other tools are measured against. The learning curve is real. Reports are spread across several sections, and the default setup records far less than people expect until you mark the events that matter as conversions.
Best for: traffic sources, conversions, and anyone who needs data that other people already understand.
2. Google Search Console
Search Console is not a traffic counter, and it does not track what visitors do on your pages. What it does is show which search queries bring impressions and clicks, which pages Google has indexed, and whether any URLs have errors. The Performance report is the one to check weekly.
It is also the only free tool here that tells you how Google sees your site. If a page has fallen out of the index or lost impressions, this is where you find out first. Once you have the query list, proven SEO tips for organic traffic cover what to change on the page.
Best for: search queries, indexing problems, and spotting pages that rank just outside the top results.
3. Microsoft Clarity
Clarity records anonymised sessions and builds heatmaps showing where people click, how far they scroll, and where they get stuck. It also flags rage clicks (repeated clicking on something that does not respond) and dead clicks, which are often the quickest route to a usability fix.
It is free with no traffic cap, which makes it useful for busy blogs. The trade-off is retention. Microsoft's documentation sets a short window for raw session playback, so save the recordings you want to keep. Check the current retention terms on Microsoft's Clarity help pages before you rely on it for long-term comparisons.
Best for: finding why a page underperforms, especially on mobile.
4. PageSpeed Insights
PageSpeed Insights tests a single URL and scores its performance, accessibility and SEO. It reports two kinds of data: lab results from a simulated test, and field data from real Chrome users when enough traffic exists for Google to have it. The field data matters more, because it reflects your actual visitors.
The metrics that count in 2026 are Largest Contentful Paint, Cumulative Layout Shift, and Interaction to Next Paint (INP). INP replaced First Input Delay as a Core Web Vitals metric in March 2024, so older guides that mention FID are out of date. For the on-page side of those fixes, see top on-page SEO tips.
Best for: checking your most visited URLs one at a time, then fixing the heaviest images, scripts and fonts first.
5. Cloudflare Web Analytics
Cloudflare Web Analytics is free and does not need a DNS change or the Cloudflare proxy. You add a small script snippet to the site. It shows page views, visits, referrers, countries and basic Core Web Vitals.
Its limits are real. It has no custom event tracking and no funnels, and its history is shorter than GA4's. Treat it as a quick traffic overview rather than a full analytics platform. If you need campaign attribution or goals tied to revenue, you will need a different tool.
Best for: a lightweight, privacy-focused check alongside GA4, particularly on small sites.
Comparison at a glance
| Tool | Main question it answers | Free limit or catch | Best starting use |
|---|---|---|---|
| Google Analytics 4 | Where do visitors come from, and what do they do? | Free for most sites; setup takes effort | Conversions and traffic sources |
| Google Search Console | Which searches bring clicks, and is the page indexed? | Free; search data only | Weekly query review |
| Microsoft Clarity | Why do visitors leave or get stuck? | Free; short retention for recordings | Heatmaps on key landing pages |
| PageSpeed Insights | Is this page fast enough for real users? | Free; one URL per test | Fixing slow templates |
| Cloudflare Web Analytics | Roughly how much traffic is there, and where from? | Free; shallow history, no custom events | A simple second opinion |
How I would set them up
Start with GA4 and Search Console on the same day, because both need time to collect data before the numbers mean anything. Add Clarity once you have a handful of pages getting regular traffic, and point it at your top three landing pages. Run PageSpeed Insights on those same URLs and fix the biggest issue it lists before touching anything else.
Review the data on a fixed schedule. A weekly 30-minute check beats a daily glance, and it stops you from changing a page because of one unusual afternoon.
Still not sure which one to start with?
If you can only install one tool, install Search Console. It is free, it shows what Google is showing people, and it takes about ten minutes to verify a site. Add GA4 next, because most of the questions about visitors need it.
