<b>Sub IDs: how you find the one ad that works</b>

Running traffic but cannot tell what is working? Sub IDs are the answer, and they are simpler than they sound.

A sub ID is a small label you attach to part of your campaign so your tracker can report on it separately. Think of it as a name tag you pin on each piece.

Why it matters: a campaign is many parts at once, many ads, many sites your traffic comes from. Without name tags, all the results blur into one average. With them, you see the winners and the losers.

Tiny example. You run three ad images. You tag them sub1=imageA, sub1=imageB, sub1=imageC. After $20 your tracker shows:
— imageA: 4 leads.
— imageB: 0 leads.
— imageC: 1 lead.

Now you know to pause imageB and put its budget into imageA. Without sub IDs, you would only see '5 leads total' and learn nothing about which to keep.

Most traffic sources can pass the source site automatically into a sub ID too. That lets you block sites that send only junk clicks.

The beginner mistake is using one sub ID slot for everything. You usually get several, often named sub1 through sub5. Give each one a clear job.

Next step: in your next campaign, put your creative name in sub1 and the traffic source site in sub2. Two tags is plenty to start.
