Sirstack runs Google Ads, media buying, ad creative and email for online stores. One team works all four, so each layer learns from the others.
Built on ten years inside e-commerce and affiliate marketing. The person who answers your message is the one working in your account.
Layer 1, the base
Search, Shopping and Performance Max, built on your margins and tracked against real orders.
Layer 2
Decides where the next dollar goes, product by product, and when to stop.
Layer 3
Static ads, video and product imagery, made from what the account data says about your buyers.
Layer 4, the top
Flows and campaigns that bring buyers back, so paid traffic pays more than once.
Tools we work in every day
The stack is more than a list of services. Each layer produces something the one above it needs, and the top layer sends its numbers back to the base.
Read how we workAnd back down: email's repeat-purchase data raises what Google Ads can afford to pay for a new customer.
Every target we set starts from what you keep on each order, after product, shipping and fees.
A ROAS figure means little without your costs behind it. Before any campaign changes, we work out the return each product needs to make money.
Work out your own numbersWe go through the account, tracking, feed and margins, then tell you what is working and what isn't.
Tracking gets fixed and the account restructured. Creative and email flows are ready before spend goes up.
Campaigns go live with set budgets, targets and the rules for cutting or pushing.
Winners get more budget, losers get replaced, and each layer feeds what it learns to the others.
Enter the numbers for one product. It is the first calculation we run on every account.
Brands selling their own product direct, with a catalogue worth structuring by margin.
Stores with a working feed and order history, ready for more traffic.
Operators testing and scaling products fast, where stop rules matter most.
Teams buying traffic to offers, measured on payout against spend.
Several stores under one owner, with budgets moved between them.
No. Many stores start with Google Ads alone and add layers once the numbers justify it.
Stores that already sell and want more volume: DTC brands, dropshipping operations and affiliate operators.
By chat and email, directly with the person who works on your account. There is no ticket system.
You do. We work with access to accounts under your name and your billing.
You tell us about the store, the margins and what you have tried. We tell you whether we think we can help, and how.
