I have put up a landing page for early customer acquisition for a grocery ordering app. After about 28,000 people reached and over 1074 clicks through Facebook ads, I am still yet to see a single sign up on my site. I have followed all the landing page and FB ad tricks I know but nothing seems to work. Thanks in advance for the help
Conversion at the page level is often impacted by who is showing up - and could be indicative of a mismatch between the ads you are running, the audience they attract, and the messaging on the landing page on arrival.
You're also asking for both a phone number and an email address - while offering very little information in return - like what cities this is available in - what it costs - how long it takes, how it's different / better than other services in this same vein.
Consider narrowing the focus of your ads down to a single city, and then customize the lander to include challenges specific to that city that this would eliminate (the long Saturday lines at XYZ Market - traffic on the crosstown etc) and reference brands and stores they'll know. The more you can make the landing page a reflection of your user and the problem you're hoping to solve for them - the better. Right now, it's not reflective at all - leaving most details to the imagination.
Once you've dialed in on the approach in a single locale, you can expand your campaign by repeating the process (still customizing per market).
I hope this helps.
