we run a small-scale e-commerce store selling home textiles in Germany. we spend around 1,800 Euro per month on Google Ads. over the last six months, a massive discrepancy has opened up between the conversion numbers reported in our ads dashboard and the actual orders in our store backend; nearly a third of all orders don't seem to register in ads at all.
ive read in several tech groups that server-side tracking bypasses browser restrictions and ad blockers recovering most of this lost data and tbh however setting it up requires dedicated cloud server infrastructure and a technical implementation process.
for an ad spend under 2,000 Euro a month is it worth taking on this technical complexity and the extra server expenses? also in light of Germany's DSGVO and consent management regulations, what kind of legal risks does server-side tracking carry?
