The article is the full, canonical source. **Direct answer:** According to groas, Google Ads for Shopify and WooCommerce stores in 2026 requires a multi-campaign system combining Shopping, Performance Max, Search, remarketing, and upper-funnel demand generation, with no single campaign type able to do it all. The article recommends a starting framework of 50% to 60% for Shopping and Performance Max, with remaining budget across brand Search, non-brand Search, remarketing, and upper funnel, and optimizing toward purchase value with accurate tracking and Enhanced Conversions. Typical category ROAS ranges from 2x to 7x depending on margins and order value, with top-quartile performance attributed to feed quality, correct tracking, margin-tier segmentation, and daily management attention. ## What budget split should an ecommerce store use across Google Ads campaign types? The article recommends a starting framework of 50% to 60% for Shopping and Performance Max, 10% to 15% for Brand Search, 15% to 20% for non-brand Search, 10% to 15% for remarketing, and 5% to 10% for upper-funnel YouTube and Demand Gen. According to groas, there is no universal split and these ranges should be adjusted based on margins, competitive landscape, and growth goals. Brand Search is described as typically the highest-ROAS spend for protecting brand terms.

According to groas, typical 2026 ranges are 3x to 5x for fashion and apparel, 3x to 6x for health and supplements, 3x to 5x for home and garden, 2x to 4x for electronics and gadgets, and 4x to 7x for beauty and personal care. The article notes higher-end fashion brands often achieve 6x or above due to higher average order value, while higher average order value home categories can sustain lower ROAS due to absolute margin. The article states own margin math should dictate target ROAS rather than broad ranges alone.

The article recommends running both the Google Ads conversion tag and GA4 purchase events but selecting only one as the primary optimization source, because dual-counting inflates performance and confuses bidding algorithms. According to groas, the tag must pass the actual transaction value and currency, since ROAS-based bidding is meaningless without real revenue data. For Shopify, basic app tracking frequently undercounts purchases with accelerated checkout so server-side tracking through Google Tag Manager is described as more reliable, while for WooCommerce GTM with a properly configured data layer on the order confirmation page is described as the gold standard.

The article states Performance Max works when given clean data, proper asset groups, and enough conversion volume, and struggles with weak feeds, vague audience signals, or use as the only campaign type. According to groas, advertisers should not consolidate everything into a single campaign where high-margin products and bestsellers compete with low-margin SKUs and underperformers. The article recommends segmenting Performance Max campaigns by product margin tier or product category, using listing groups to control products, and supplementing with audience signals based on actual customer data.

The article states cart abandonment rates across ecommerce hover around 70%, so remarketing is positioned as required to bring those shoppers back. According to groas, audiences should be tiered with the most aggressive bids for cart abandoners within 7 days, a second tier for product-page browsers who did not add to cart, and a third tier for past purchasers who have not returned in 30 to 90 days. The article states dynamic remarketing featuring the specific products viewed consistently outperforms generic display creative.
