      Kerry Jamison's Review Sourced from Google

      It was a pleasure working with Robert Long on a complete revamp of our company website. Our business has used his services for decades but it was the first experience for me. Robert had the creative vision and technical expertise to make the website do everything we needed it to do for an easy-to-navigate, intuitive, user-friendly experience, all while keeping the look and feel of the brand. The final product is more than I ever imagined, providing both helpful information and a strong marketing tool. Robert was an excellent project manager and true professional, building a framework from the start, checking in throughout the process with updates, and able to flex in different aspects as our business offerings evolved. I wouldn't hesitate to recommend Seller's Bay to anyone looking to build or remodel their website.

      Robert with Sellers Bay is all over it. I hired him to build us a new website and manage our Google face to the public. I had a meeting with him prior to start and he was all over it after that meeting. Started almost immediately and got us built up fast. Now we are getting calls based on the Google ads. We have been so pleased with his work we are going to have him move and improve our other website too. I highly recommend Robert with Sellers Bay.

      Highly recommend Sellers Bay, very responsive, upfront about the services that were to be completed for my new website, no surprise charges or anything like that. I dealt with Robert, he was able to make the website look exactly how I wanted it. I am very picky with this type of stuff, and he never had a problem fine tuning everything that I mentioned to him Also, very honest, polite, and easy to work with. Thank You!!!

Frequently Asked Questions About eCommerce Marketing Agencies

What services do eCommerce marketing companies provide?

ECommerce marketing agencies provide a broad range of advertising services to help online stores attract more visitors, acquire new customers, increase conversions, and grow revenue. Key services include:  

  • Search engine optimization (SEO) and product page optimization  
  • Paid advertising on Google, Meta, TikTok, and other platforms  
  • SMS/Email marketing and automation  
  • Social media management and influencer marketing  
  • Conversion rate optimization (CRO)  
  • Content marketing and campaign design  
  • Performance tracking, analytics, and reporting  
  • Retargeting and customer retention strategies 

How much do these services cost?

Most eCommerce marketing companies charge between $3,000 and $10,000 per month for end-to-end. Higher scope projects with intricate, multi-channel strategies go from $15,000 to $50,000+ per month.   

In general, each service entails a different price: 

  • PPC management: 10% to 30% of ad spend or flat fees from $500 to $5,000+  
  • SEO retainers: $750 to $5,000/month or up to $30,000+ for large businesses  
  • Social media: $1,000 to $7,000 per month  
  • CRO retainers: $5,000 to $10,000 per month  
  • Email marketing: $500 to $5,000 per month 

What kind of ROI can businesses expect from eCommerce marketing?

Most eCommerce marketing campaigns deliver an average ROI of 200% to 300%, meaning every $1 spent typically generates $2 or $3 in revenue.   

However, returns also vary by channel:  

  • Google Ads (Search): 800% ROI  
  • Facebook Ads: 150% ROI  
  • Email marketing: 4,400% ROI  
  • Influencer marketing: 150% ROI  
  • Content marketing: 300% ROI  
  • Affiliate marketing: 1,200% ROI 

How long does it take to see results from eCommerce marketing campaigns?

In general, search engine marketing (SEM) and paid social initiatives yield conversion data within 14 to 30 days. Conversely, organic traffic strategies like search engine optimization (SEO) and content marketing need longer, often requiring 6 to 12 months to achieve significant domain authority and good ranking for target keywords.  

Mid-funnel initiatives such as email automation and retargeting campaigns see incremental returns within 45 to 60 days when lead nurturing cycles start to mature.  

What are the most effective strategies recommended by eCommerce marketing firms?

In 2026, eCommerce marketing firms focus on the following strategies to maintain competitive advantage: 

  1. Generative engine optimization (GEO) 
    As retail websites witnessed a 4,700% rise in traffic via AI assistants between 2024 and 2025, visibility within zero-click generative summaries has become a primary driver for top-of-funnel customer acquisition. 
  2. Augmented reality (AR) visualization 
    Brands who have enriched their sites with AR-based product visualization report that return rates related to sizing and fit issues have declined by over 20%
  3. User generated content (UGC) 
    92% of consumers trust peer-recommended products over brand ads, and product pages featuring customer videos or photos see a 161% improvement in conversion rates. 
  4. Live commerce 
    Live shopping events on TikTok and Instagram report conversion rates of nearly 30%, which is 10x higher than traditional eCommerce formats.
