Hire an eCommerce PPC Manager: agency, freelancer, or in-house?
An eCommerce PPC manager lives in the product feed, Shopping and Performance Max structure, and margin-tier bidding, because in feed-driven advertising the feed is the targeting. Indeed's average base for a paid search manager is $80,280 (September 2026), about $100,000 to $112,000 loaded. Catalog complexity and spend decide between agency, freelancer and in-house.

Feed and Shopping: where performance is won
Shopping eligibility and matching are governed by the feed. Titles and attributes decide which queries a product can match; GTINs, brand fields and image quality decide whether it shows at all; custom labels carry margin tier, seasonality and hero-product flags so bidding can treat products differently. Take two products at the same 4.0 ROAS, one at an 80 percent margin and one at 20 percent: bid them the same and you quietly scale the loser. Only per-SKU margin in custom labels lets the campaign tell them apart.
The other half is protection. A good manager diagnoses Merchant Center disapprovals before they silently remove live products, keeps price and availability in sync so ads never promote out-of-stock or mispriced items, and decides which products belong in Standard Shopping and which in Performance Max. A common hybrid keeps feed data ownership in-house, where merchandising and inventory data originate, while an agency runs the Merchant Center and campaign layer.
Performance Max guardrails
Performance Max hides more than any other campaign type, so the manager's work is structural. Asset groups get split by margin tier or product economics, with a target ROAS per group set from the margin table. Brand exclusions stop the campaign absorbing branded search and inflating its own ROAS. Audience signals get tuned and checked for whether they actually speed up learning.
Reported results are never taken at face value: Performance Max ROAS is reconciled against Shopify or GA4, and the limited reports, search categories and asset performance, are read for real signal. When a product line needs more control than the campaign allows, it moves out to a dedicated Shopping or Search campaign. The first two checks on any inherited account are whether branded search is being absorbed and whether asset groups are split by margin.
Move to an in-house eCommerce PPC manager once spend and catalog complexity justify a full salary and the tight loop with merchandising becomes a real advantage. Below that, an agency or senior freelancer usually wins on feed expertise and cost. At high spend or with a large catalog, a hybrid, in-house owner plus agency for feed engineering, reconciliation and structural resets, is common.
