Most website audits open with page speed and broken links, and the owner nods politely because none of that feels like money. Here's a test that does, and it takes about 20 minutes for a list of ten prospects. Step 1. Pick ten businesses in one trade where a missed call means a lost job (plumbers, HVAC, roofers, garage doors, auto shops). Step 2. Call each one twice: once mid morning, once around 5:30pm. Use the number on their Google Business Profile, not the website, since that's the one most customers tap. Step 3. Log four things per call: answered live, voicemail, full mailbox, or rang out. Note how many rings before voicemail and whether the greeting even says the business name. Step 4. If you hit voicemail, don't leave a pitch. Just note whether anyone calls you back within 24 hours. In most trades you'll find a good share of those 20 calls never reach a person, and the after hours ones are usually worse. That list is your opener. Instead of "your site could be faster," you get to say "I called you Tuesday at 5:40 and it rang out. How many of those do you think you get a week?" Owners argue with design opinions. They don't argue with their own call log. How to use it in the pitch: Show the result in a simple table (day, time, outcome), one row per call. Then connect it to the work you sell: the website and GBP make the phone ring, reviews make them pick you, and none of it pays if the call goes nowhere. It also gives you a clean before and after number to report in month one, which helps a lot with retention. Full disclosure, I build CallPayWall, which sits behind the owner's number: their phone rings first and only the calls they miss get answered, so it slots into a website plus reviews package that agencies resell at their own price. Weigh my bias on that part, but the test works no matter what you end up selling. If you run it this week, post what percentage of calls went unanswered in your niche. Curious how much it varies by trade.
