Four Free Tools That Show Where Your Sales Come From

Your ad platforms are lying to you. They don't mean to, but they do. Each one takes full credit for the same sale, so your reports show a number that looks great and tells you almost nothing useful. The good news: you can fix that with free tools you can set up this week.

This is part of the "Where Sales Come From" mini-series. The through-line is simple: you can't grow what you can't measure. Sales don't come from guessing. They come from reading the signals your business already produces.

Play 1: Find Out Which Ad Made the Sale (UTM + Google Analytics)

The problem: Every ad platform takes credit for every sale. Run ads on Meta, Google, and TikTok at the same time, and all three dashboards will show conversions for the same buyer. According to Ruler Analytics, ad platforms can collectively claim 30 to 50 percent more conversions than occurred. In their example, platforms reported 175 conversions against 95 actual sales. That's an 84% overcount.

You're not spending on ads. You're funding three scoreboards that all have a reason to say they won.

The fix:

1. Go to Google's Campaign URL Builder. It's free. Takes 30 seconds.
2. Build a unique tracking link for every ad you run. Add your source (meta, google, tiktok), medium (paid-social, cpc), and campaign name.
3. Use that link in your ad instead of your plain website URL.
4. Connect Google Analytics (free) to see where clicks come from.

In GA4, look at two views: first-touch (where the buyer first heard of you) and last-touch (what pushed them to buy). They're often different channels, and both matter.

Once you see which source drives real buyers, stop splitting your budget evenly. Put it where the data points.

Safety note: Don't change live ad links mid-campaign. Build the UTM links before you launch. Changing them partway through breaks your tracking history.

Play 2: Watch Where People Give Up on Your Site (Microsoft Clarity)

The problem: Analytics tell you people leave your page. They don't tell you why. You see a 70% bounce rate and you have no idea if the button didn't work, the page loaded too slow, or the copy just lost them.

The fix:

Microsoft Clarity is free, and it says so right on the homepage: "Free forever." It records real, anonymous visitor sessions so you can watch exactly what people do on your site. It also builds heat maps that show where visitors click, where they scroll to, and where they stop.

1. Create a free Clarity account.
2. Add the tracking code to your site. (If you're on WordPress, there's a plugin.)
3. Don't try to watch every session. Pick your weakest page, the one with the lowest conversion rate or the highest exit rate, and watch five sessions in a row.

One obvious problem usually shows up in the first 10 minutes. A button that doesn't work on mobile. A form that's cut off. A product image that's taking too long to load. Fix that one thing first.

Clarity is GDPR and CCPA ready, so visitor data is anonymized. You see behavior, not identities.

Play 3: Turn Your Charts Into One Clear Action (Plausible or PostHog + AI)

The problem: Most analytics tools give you 50 numbers and no direction. You open the dashboard, feel overwhelmed, and close it. Nothing changes.

The fix:

Switch to something cleaner. PostHog has a free plan, no credit card required, with 1 million events per month included. Plausible offers a 30-day free trial with no credit card, and it's built to be simple by design.

Both tools show you what matters without the clutter.

Then do this: take a screenshot of your analytics dashboard. Open ChatGPT or Claude. Paste the screenshot and ask: "What's the one thing I should fix on my site this week based on this data?"

You get a clear, specific action instead of a list of metrics to interpret. The AI spots patterns that are easy to miss when you're too close to your own business. You're not outsourcing the decision. You're just getting a faster read on what the data is telling you.

Check your dashboard once a week. Screenshot it. Ask the question. Act on the answer.

Play 4: Find Out Which Product Makes You Money (Spreadsheet + AI)

The problem: Revenue feels good. Profit is the real number. Most small business owners know their best-selling product but have no idea which one makes them the most money after all costs.

Product cost, shipping, platform fees, packaging, and ad spend to sell one unit. Add those up and the picture changes fast. Your top seller might be your worst performer.

The fix:

Open a spreadsheet. List every product or service. For each one, add a column for price, product cost, shipping, platform or transaction fees, and how much you spend in ads to sell one unit.

Then open ChatGPT or Claude. Paste the spreadsheet data and ask: "Which product makes me the most profit? Which is breaking even? Which should I cut or reprice?"

You'll get a clear breakdown in seconds. Most business owners are surprised. The product with the most sales is often not the one that makes the most money. Sometimes it's actively losing money once all the real costs are in.

Once you know your true profit per product, you can make real decisions. Reprice what's too cheap. Kill what's bleeding. Put your marketing energy behind what pays.

Quick Recap

• Ad platforms all take full credit for the same sale. UTM links and Google Analytics show you which source drove the buyer.
• Microsoft Clarity lets you watch real sessions for free. Five sessions on your weakest page is enough to find one fix.
• Plausible and PostHog give you clean dashboards. A screenshot plus an AI prompt turns data into one clear action.
• Revenue is a vanity number. Profit is the truth. A spreadsheet with real costs, handed to AI, shows you which products to grow and which to cut.
• You can't grow what you can't measure. These four tools cost nothing and give you the signals you need.
