FAQs

Q.1 What is “Feed Management” and why is it critical for e-commerce PPC?

Ans. Your product feed is the data source (images, titles, prices) for Google Shopping and Meta Catalog ads. If your feed is messy, your ads won’t show for the right searches. Best ecommerce ppc agencies optimize this data to ensure maximum visibility and relevance.

Q.2 Should I focus on Google Ads or Amazon Ads?

Ans. For most brands, the answer is both. Google captures intent when users search, while Amazon captures intent when users are ready to buy. A balanced strategy covers the entire funnel.

Q.3  How do agencies charge for PPC management?

Ans. Most charge a percentage of ad spend (usually 10-20%), ensuring their incentives are aligned with scaling your account. Some ecommerce growth ppc firms offer performance-based models or flat retainers for smaller accounts.

Q.4  What is “Performance Max” (PMax)?

Ans. PMax is Google’s AI-driven campaign type that serves ads across all Google inventory (YouTube, Display, Search, Maps) from a single campaign. Leading agencies know how to “guide” this AI with the right assets and audience signals to prevent wasted spend.

Q.5 Can these agencies help with Shopify stores?

Ans. Yes, most shopify ppc agencies have specific expertise in the Shopify ecosystem, understanding how to install pixels, configure conversions, and use apps to enhance marketing performance.

Q.6 How long does it take to see results?

Ans. While PPC can generate traffic instantly, optimizing for profitability typically takes 1-3 months of testing and data gathering (the “learning phase”) to refine audiences and bids.

Q.7  Which of the best ecommerce ppc agencies is best for D2C brands?

Ans. Wildnet Marketing Agency is frequently cited as a top choice for D2C due to their agile “Engineering Growth” framework, which combines rapid creative testing with rigorous data analysis to scale emerging brands profitably.
