Dynamic number insertion for your website

How the snippet works

You add one script tag to your site. When a page loads, the script:

1. asks VereTel which tracking number belongs on this page, sending the page’s address;
2. receives a short list of swaps: your usual number, and the tracking number to show instead;
3. replaces only those numbers, both in the text visitors read and in tap-to-call links.

If anything goes wrong, whether the script is blocked, the network is slow or a page is not registered, the page simply keeps the number it was published with. Visitors always see a working number.

Per site and per page, not per visitor

VereTel’s number insertion assigns numbers by site and by page. Every visitor to a given page sees the same tracking number. It does not hand each visitor a number of their own, and it does not follow a visitor from page to page.

That design is simple and predictable, and it shapes how you plan your pages:

• give each campaign its own landing page, and each landing page its own number, when you want campaigns compared;
• register your main site with one number to measure calls from people who found you directly or through search;
• if you run more than one site, each site can have its own number.

What the snippet sends

To choose a number, the script sends the address of the page being viewed and the site the visitor came from (the domain only, not the full address). It also passes the campaign source tag if the link carried one, and whether the visit came from an ad click, as a yes or no rather than the click identifier itself. It sends no names, form entries or contact details.

Setting it up

Once you have numbers, you register your sites and the pages that should show a tracking number, and choose the number each one shows. You or your web person paste one tag into the site’s template. A free account includes a test tag to try first: only your own test link switches it on, and real visitors send nothing. The DNI product page walks through the planning step, and number insertion is included in every plan. Numbers are not on sale yet. Create a free account and ask to be told when they are.
