Top 12 Ecommerce Performance Marketing Agencies Helping Brands Scale

The top ecommerce performance marketing agencies assist brands in expanding by generating quantifiable revenue, fine-tuning conversion rates, optimizing multi-channel ad spend, and increasing the return on this spend. Here are 12 agencies for you to read about and select the best. 

When choosing an ecommerce performance marketing agency, it’s not enough to look for a service provider that will just advertise. An ideal marketing agency should have knowledge about your products, clients, margins, sales cycles, and growth targets. An experienced partner should also know where the money you allocate on marketing is spent and what value does every channel provide in terms of revenues generated.

There are three critical aspects that ecommerce companies should take into consideration before choosing an agency, namely, acquisition, conversion, and retention. Acquisitions include paid search, paid social, shopping campaigns, and any other sources used to attract new visitors. Conversions deal with landing pages, product pages, checkout process, and offers. Last, retention is achieved through email campaigns, retargeting, client loyalty programmes and repeat purchase.

What Kind of Ecommerce Performance Marketing Agency Should You Select?

It is contingent upon how mature your business is at the moment. Metrics, product positioning, paid traffic, and conversion optimization can be challenging for an early-stage ecommerce business. As a brand grows you could need more sophisticated campaign management, creative testing and customer retention work. And a bigger brand will need cross-channel attribution, and more detailed reporting and international growth.

Here is the simple five-step framework to follow before signing any contract:

1. Set out your goal.

Do you need more revenue, reduction of customer acquisition costs, better conversion rates, higher retention, or market expansion? Do not pick an agency until you have decided on your major business issue.

2. Check out their relevant experience.

Ask whether they have run campaigns for other ecommerce brands like yours by product type, average order value, customer base and sales model.

3. Identify how performance will be measured.

See which metrics will make it into monthly reports. At the very least, consider the following: revenue, conversion rate, customer acquisition costs, return on advertising spending, average order value, and repeat purchase rate.

4. Learn about the testing approach.

A good performance marketing strategy should involve constant testing, which includes testing various ad creatives, headlines, audiences, offers, landing pages, product feeds, and campaigns.

5. Create a 90-day road map from the start.

The first 90 days can be split into three parts:

• Days 1 to 30: Auditing tracking, campaigns, customers, website performance, and existing creatives.
• Days 31 to 60: Starting/optimizing campaigns and conducting creative and audience tests.
• Days 61 to 90: Analyzing results, cutting underperformers, allocating budget for profitable campaigns and creating next test plan.

E-commerce Performance Marketing Agency Checklist

Before considering an agency, refer to this checklist:

• Properly set up Google Analytics and conversion tracking
• Advertising accounts are set up correctly
• Product feeds are correct and current
• Conversion and revenue metrics are verifiable
• The agency has experience with your business model
• The report shows business results, not just clicks/impressions
• There is a creative testing methodology
• Landing pages and product pages are analyzed
• Retargeting and customer retention are taken into account
• The agency offers a strategy and communication plan

 A Basic Performance Marketing Optimization Example

Let’s imagine an ecommerce company that makes $100,000 a month in revenue through its website. Rather than simply doubling its ad spend, the company should examine where its sales are coming from. Paid search is showing good conversions while one paid social media ad campaign has shown great traffic, but no sales. Then the agency could reallocate part of its budget to the successful campaign and test new creative for the other campaign along with improving the landing page.

This strategy shows one more rule of performance marketing which is that growth needs to be driven by results and tests. Investing without analyzing the economics of the campaign may result in increasing expenses and not generating revenue from it.

In addition to ROAS, brands need to take into account other factors. For instance, one campaign might generate high ROAS from the first purchase but get customers that will never buy again, whereas another campaign may generate lower ROAS but attract loyal customers. In this regard, customer lifetime value will help assess the performance of a campaign more efficiently.

Questions to Ask Before Hiring an Agency

Before making the final decision, ask the following questions from each agency:

• Do you have any experience in working with ecommerce companies like mine?
• Which channels do you suggest for my products and why?
• How will you evaluate the profitability of the campaign?
• How often will the campaigns and creatives be tested?
• Which information will be provided in the monthly reports?
• Who will handle my account and coordinate with me?
• How do you deal with underperforming campaigns?
• What should I expect from your services in the first 90 days?

It will allow you to evaluate the agencies by their strategy and process approach rather than just looking at ratings and sales pitches.

FAQs about E-commerce Performance Marketing Agencies

1. What does an ecommerce performance marketing agency do?

An ecommerce performance marketing agency assists online brands in achieving business results through channels like paid search, paid social, shopping campaigns, conversion optimization, analytics, email, and remarketing. It all depends on what the agency does and what your goals are.

2. How much should my ecommerce brand allocate to performance marketing?

It all depends on your profit margins, average order value, customer acquisition costs, conversion rates, and growth plans. It is recommended that you start off with a budget where you can conduct effective tests without compromising cash flow and scale up your successful campaigns.

3. What KPIs should I measure?

Among other things, you will need to track revenue, conversion rate, customer acquisition cost, return on ad spend, average order value, cost per conversion, repeat purchase rate, and customer lifetime value. A combination of several metrics is always better than one metric.

4. How much time do I need to see results?

While some advertising efforts can show quick results, the sustainable process of optimization is generally a process that involves constant testing and evaluation. The first few weeks of the campaign are helpful for gathering information and finding problems, and 60-90 days will be sufficient to evaluate the overall strategy.

 5. Do I need an agency for Google Ads and social media?

It depends on your company’s internal capabilities in terms of time, budget, and expertise. An advertising agency will be helpful if you need certain professional expertise or extra people for testing your marketing strategy.

6. What should I be looking for in an agency report?

An informative report should link marketing efforts to business performance. Search for information regarding expenditure, conversion, income, acquisition cost, ROI, trends in campaigns, testing that has been done and recommendations for future periods.

7. Does it mean that the agency with the highest rating is the best option?

No, it does not. While ratings can prove helpful when trying to compare different providers, they shouldn’t be the only criteria for making decisions. Such things as industry experience, strategy, communication, reporting, pricing and ability of the agency to understand your ecommerce business also matter.
