Best AI Tools for E-commerce PPC in 2027: Shopping, Performance Max, Meta Catalog Ads and Feeds

Ryze AI connects to Google Ads and Meta with a sign-in and checks both several times a day. On Google it reads every campaign type through the API, Shopping and Performance Max included, and changes budgets, bids and keywords, pauses and ads under your approval settings. On Meta it creates campaigns, adjusts budgets, pauses ads and swaps creatives. Because one agent sees both accounts, it can move money toward the channel that is selling. The same connector gives Claude and ChatGPT Shopify data next to the ad accounts, and the Ryze AI pixel can send conversions server-side to Google and Meta. What the platforms already do: PMax and Advantage+ set bids inside each campaign; Ryze AI works across campaigns and channels. Paid Ads is $89 a month flat with a 7-day trial; the Shopify CRO plan at $1,499 a month adds A/B tests run by the Ryze AI team, SEO and paid ads together.

Performance Max is the default campaign for many stores: one campaign across all Google Ads inventory, bidding toward a conversion value or ROAS goal from your Merchant Center feed and assets. AI Max adds broader search matching, ad text customization and landing page selection to Search, and Google's help center now lists AI Max for Shopping campaigns too. It is free beyond your ad spend and uses Google's signals, which no third party has. The limits for a store: product-level control comes only through listing groups and custom labels, it optimizes toward the values you send (so margin is invisible unless you pass it), and channel decisions are Google's.

Advantage+ sales campaigns hand audiences, placements and budget split to Meta's delivery system, and catalog ads build a personalized ad for each product from your feed, shown to people who viewed or are likely to want it. Meta's ads AI connectors let Claude or ChatGPT manage the catalog itself: create it, add product data and troubleshoot feed issues. It costs nothing beyond your spend. The limits: Meta decides delivery with little explanation, the feed still needs work, and nothing here compares Meta's results with Google's.

smec (Smarter Ecommerce) builds software and services for retailers on Google. Its Campaign Orchestrator brings first-party business data such as margins and customer lifetime value into paid search and Performance Max, so campaigns follow profit goals and products move between campaigns with different targets. smec also offers marketing mix modeling, a CSS for Google Shopping and an agency service; its site says it manages 620 million in Google Ads budget. What Google already does: PMax bids toward revenue; smec makes it bid toward margin. Pricing is on request. It suits mid-size and large retailers with big catalogs and covers Google only.
