Fix Facebook Audience Populating

My website receives hundreds of visits to certain product pages every week, yet the Facebook custom audience that should be fed by that traffic stubbornly stops at about 20 people. I built the audience to target people who visited specific product or service pages, but it simply will not refresh beyond that tiny pool.

I need someone who can dive into the setup, check the pixel, event tracking, and any configuration conflicts, then get the audience to reflect the real volume of visitors from my site. Once you’re done, the custom audience based on “People who visited my website”—specifically those key product pages—should update accurately and keep growing as new visitors arrive.

Please let me know the steps you’d take, any diagnostics you’ll run, and how long you expect the fix to take.
