1. Using one number across several sources
If the same tracking number appears on your postcard, your social ads and your website, you have one count for three sources. The calls are logged, but you cannot tell them apart, which defeats the purpose.
Fix: give each source you want to compare its own tracking number. Sources you would judge together can share one.
2. Printing numbers without labels
A number is only useful if you remember what it stands for. Six months later, nobody recalls which of the numbers was for the fall mailer. Unlabeled numbers turn into a puzzle at the moment you need the answer.
Fix: every VereTel number carries a label such as “Mailer · October,” shown next to each call in the desk. Keep your own list of numbers, labels and start dates too, so the record does not live in one place.
3. Forgetting about missed calls
Agencies tend to look at the calls they answered. The calls that rang and went unanswered are the ones costing you leads, because the caller often tries the next agency. A source with a high missed call rate looks better than it is if you count only the answered ones.
Fix: VereTel logs missed calls too. Filter the call list to missed calls each day during busy periods and call back. Compare answered and missed by number, not only totals.
4. Changing numbers mid-campaign
Swapping a number partway through splits the data in two and strands anyone who saved the old one. Printed pieces stay in circulation for weeks, and callers who keep a mailer will dial its number long after you stop paying for the campaign.
Fix: hold a number for the life of its campaign and a while after. Start new campaigns on new numbers. If a number must change, note the date so you can read the two periods separately.
5. Letting your listings disagree
Tracking numbers belong on the source they measure, not on every listing. But if you put a tracking number on a directory profile, or your main number differs from one site to the next, your name, address and phone details (NAP) stop matching across the web. Search engines and callers both notice.
Fix: keep your main local number and address consistent on your website, Google Business Profile and directories. Use a tracking number on a listing only deliberately, and keep the main number on the profile as the primary one where the platform allows. For a website, number insertion swaps the number for visitors while the published number stays in place.
6. Not sizing minutes
Plans include a set number of minutes. An agency that adds tracking in the weeks before a busy season, then sees calls double, can pass its allowance. Overage is $0.06 a minute, which is fair but avoidable.
Fix: estimate calls times average length before the season, and pick a plan with room. Look at pricing and the ROI calculator. If you are unsure how many numbers you need, ask us and we help you plan.
Why these mistakes are easy to make
None of these need a technical error. They come from a busy office reusing a number because it is handy, or reprinting a flyer at the last minute with whatever number is nearest. The fix in each case is a small rule, written down and shared with whoever orders print, buys ads or edits the website.
One rule covers most of it: a number is never published until it has a label, a source and a test call. If you want help deciding how many numbers and which sources, ask us and we help you plan. See tracking numbers for how they work.
A short habit that prevents most of these
Once a month, list your numbers, their labels and where each is published. Make one test call to each. Five minutes, and it catches mis-typed numbers and forgotten campaigns before they cost you. For the season-specific version, see the open enrollment checklist.
