Should I run both Amazon Ads and Google Shopping simultaneously?
Most brands that sell on Amazon and operate their own website do run both. Amazon Ads protects marketplace visibility and drives sales within Amazon. Google Shopping drives traffic to owned channels where margin is higher. The channels don't cannibalize each other because they serve different destinations. The risk to manage is customer journey confusion — some brands see cheaper Google Shopping clicks but lower conversion rates compared to Amazon, because the owned-site checkout experience is harder to optimize than Amazon's one-click purchase flow.
Which platform has better ROAS for consumer products?
Amazon Ads typically delivers higher reported ROAS for consumer products sold on Amazon because the purchase intent is later-stage and attribution is closed-loop. Google Shopping ROAS comparisons depend heavily on your own website's conversion rate, the competitive density of your product category in Google Search, and how well your product feed is optimized. Neither platform universally outperforms the other — the right comparison is within your own account, tracking the same product category on both platforms over the same period.
What is Google Merchant Center and how does it relate to Google Shopping?
Google Merchant Center is the platform where you upload and manage your product feed — the structured data file that tells Google about your products, prices, availability, and images. Google Shopping Ads are served using this feed data. You need a Merchant Center account to run any Shopping ads or appear in the free Shopping listings. Think of Merchant Center as the product database layer and Google Ads as the bidding and campaign layer on top of it.
Do I need a large budget to compete on Amazon Ads?
Amazon Ads requires consistent spend to maintain visibility in competitive categories — the auction is keyword-based, and bid levels in popular categories can be substantial. Smaller brands can compete effectively in niche categories with lower CPCs. The more important constraint is that underinvesting in Amazon Ads when competitors are spending heavily risks organic rank suppression over time, because advertising activity influences organic placement through the A9 algorithm. Budget requirements vary dramatically by category and competition level.
