PropellerAds on your landing pages
Push and pop traffic is cheap and huge, and most of it won't convert. PropellerAds makes it workable with zone-level optimization, CPA Goal pricing and its Smart Optimization tool, and every one of those needs to know which clicks became conversions. PropellerAds says it plainly: S2S tracking is required for conversions to show in your statistics and mandatory for CPA Goal and Smart Optimization.
LanderLab can send that postback directly. A hidden field saves the click ID PropellerAds put on your URL, and when the lead submits, the page's webhook calls PropellerAds' postback with it. When the form is on your landing page, you skip the tracker and the monthly fee.
It fits buyers testing lead gen on push and pop: insurance quotes, auto loans, finance and utility offers, where volume is high and the lead form is the conversion.
PropellerAds S2S tracking straight from the landing page
PropellerAds gives every click a unique ID on your landing page URL. A hidden field saves it with the lead, and when the form is sent, the page's webhook posts it back to PropellerAds, which matches it to the click and adds the conversion to your statistics.
PropellerAds notes conversions can take up to 24 hours to register in its stats, so judge a new campaign on a full day of data.
CPA Goal campaigns that learn from leads
CPA Goal and Smart Optimization move spend toward the zones that hit your target. Only the main postback counts for CPA Goal, so make it the event you get paid on. If that's a qualified lead rather than every submit, send it through a workflow: an If on the qualifying answer, then the HTTP Request node with the postback.
Later stages, like a lead the buyer accepted, can go back as secondary goals for reporting without confusing the optimizer.
Zone-level data on every lead
Push traffic lives and dies by zone. Pass the zone, the campaign and the OS on your target URL, keep them with hidden fields, and every lead in your CRM or sheet carries the zone that sent it. Cross that with what your buyer accepted and you know which zones to block, beyond what PropellerAds' own stats show.
Keep the SUBID through a pre-lander
Many push funnels use a short pre-lander before the form. Pass Through URL Params forwards the SUBID and every other token to each link, so the page that captures the lead still has the click ID the postback needs.
