  • Focus on marketing strategies with proven returns, such as email marketing, which boasts an average ROI of 3,600%. Diversifying into emerging technologies like AI-driven product recommendations further enhances results.
  • Businesses that allocate part of their budget toward continuous improvements tend to see better marketing ROI. This leads to higher revenue, which in turn allows for more reinvestment in development, creating a cycle of growth.
  • Staying adaptable by testing, iterating, and reallocating funds based on performance ensures better budget efficiency. Use AI and automation tools to streamline marketing efforts, reducing costs while enhancing targeting and personalization.

Key Components of an eCommerce Marketing Budget

An effective marketing budget for eCommerce is a strategic approach to ensure your investment pays off. Navigating the complexities of digital marketing can be daunting, so here’s some advice: take time to understand what makes up a robust budget and ensure each component aligns with your business goals.

By covering your bases, you can create a plan that is both comprehensive and adaptable to market trends. A successful eCommerce marketing budget should account for the following components:

  • Advertising costs: Pay-per-click (PPC) campaigns, social media ads, Google Ads, and display advertising.
  • Content marketing: Creation of blogs, videos, infographics, and other engaging media.
  • Email marketing costs: Subscription fees for email platforms and associated creative work.
  • SEO and website optimization costs: Investments in keyword research, technical SEO, and user experience improvements.
  • Tools and software: Analytics platforms, customer relationship management (CRM) tools, and eCommerce software.
  • Influencers and partnerships: Collaborations with social media influencers and affiliate marketers can build authentic connections that deliver great ROI.

While many businesses treat development and marketing as separate budgets, the most successful ones view them as interconnected, according to Caleb Bradley, CEO and Founder of Bighorn Web Solutions, even to the point of having shared budgets or a percentage of budget overlap.

This is because a well-optimized eCommerce platform lessens the need for paid marketing by boosting organic visibility, improving the user experience and driving higher conversion rates, he says.

Bradley observes that “businesses that allocate a portion of their budget toward continuous improvements (such as site speed, automation, personalization, and A/B testing) often see better marketing ROI which leads to higher revenues which in turn open the door for budget allocation increase for future development initiatives and so on in a virtuous cycle.”

Creating an eCommerce Marketing Budgeting in 9 Steps

Follow these nine steps to build your eCommerce marketing budget:

  1. Evaluate and analyze
  2. Use a good template
  3. Invest in high ROI channels
  4. Test, iterate, and stay agile
  5. Optimize with automation
  6. Choose the right eCommerce platform to scale efficiently
  7. Factor seasonality and capitalize on shopping events
  8. Focus on customer retention
  9. Regularly review budget performance

1. Evaluate and Analyze

Start by analyzing past marketing performance, tracking certain metrics to identify successful strategies that worked for past campaigns, and identifying any areas for improvement.

Start by monitoring essential metrics:

  1. Customer lifetime value (CLV): Shows a customer's total revenue over time, helping prioritize retention and maximize profitability.
  2. Bounce rate: Indicates how many visitors leave without engaging. A high rate flags issues with content, design, or load times.
  3. Average order value (AOV): Tracks the average spend per order, guiding pricing, upselling, and promotion strategies.
  4. Cart abandonment rate: Reveals where customers drop off during checkout, pinpointing areas to improve conversions.
  5. Email open and click-through rates: Measures email campaign engagement, highlighting what resonates — or doesn’t — with your audience.
  6. Retention rate: Tracks how well you keep customers returning, reflecting satisfaction and loyalty.
  7. Social media engagement: Gauges how well your content connects with your audience, boosting awareness and trust.
  8. Cost Per Click (CPC): Measures the amount you pay for each click on your ads. It helps evaluate the cost-efficiency of your paid advertising campaigns, guiding budget allocation and bidding strategies to maximize ROI.
  9. Cost Per Acquisition (CPA): Calculates the cost to acquire a new customer or conversion. It assesses the profitability of your marketing efforts, indicating whether the investment in campaigns aligns with customer lifetime value (CLV).

Pay attention to which of your campaigns delivered the highest ROI and note areas where performance lagged. It’s best to prioritize evaluating your target audience’s engagement patterns and preferences to refine future strategies.

You can do this by:

  • Analyzing website analytics: Use tools like Google Analytics to track page views, traffic sources, and time on the page.
  • Monitoring social media insights: Check likes, shares, comments, and audience demographics to gauge content performance.
  • Evaluating email campaigns: Track open and click-through rates and conduct A/B testing to optimize messaging.
  • Gathering customer feedback: Use surveys or reviews to understand audience preferences and pain points.
  • Using behavior tracking tools: Tools like Hotjar can reveal how users interact with your site, such as clicks and scroll patterns.
  • Researching search trends and keywords: Leverage tools like SEMrush to align content with what your audience is searching for.
  • Comparing competitor engagement: Use platforms like SimilarWeb to identify successful strategies and gaps in your approach.
  • Segmenting your audience: Break down customer demographics and behaviors with CRM tools like HubSpot to tailor strategies.

2. Use a Good Template

A structured eCommerce marketing budget template ensures that no critical aspect is overlooked. It should include categories like advertising, content creation, tools, and miscellaneous expenses. Templates also simplify tracking and make it easier and more efficient to adjust as you go.

We created this marketing budget template for eCommerce businesses to make your planning process even more seamless.

3. Invest in High ROI Channels (and Diversify)

To maximize revenue, you’ve got to invest in channels that deliver the best ROI. Focus on marketing strategies that have consistently delivered strong returns. That might include email marketing, for instance, since it allows you to nurture relationships with customers through personalized campaigns, promotions, and product recommendations — and is highly cost-effective.

For every $1 spent on email marketing, $36 is made in return, according to email marketing data from Litmus. That equals 3600% ROI.

Retargeting ads can also deliver great results for eCommerce businesses, as they target visitors who have previously interacted with your site but didn’t make a purchase, increasing the chances of converting them into buyers.

Diversify your marketing budget by exploring new and emerging channels that resonate with your target audience. This could include social commerce platforms like Instagram or TikTok, where users are already making purchasing decisions. Consider experimenting with newer technologies like AI-driven product recommendations or interactive ads.

Build with Marketing in Mind

An SEO-optimized architecture along with fast page load speeds and frictionless checkout experience are the most important things to get right for a new eCommerce store, according to Bradley.

Thereafter, additional UX elements — like AI for profit-driven merchandising capabilities, AI-powered predictive segmentation and site personalization, site search functionality and guided selling, or even "create your own product bundle" options — will have a greater impact. “The ways consumers are buying is changing and our technology is rapidly changing largely thanks to AI advancements,” he adds.

4. Test, Iterate, and Stay Agile

To stay updated with rapidly changing market trends, you should allocate a portion of your budget specifically for experimentation. Test different campaigns, ad creatives, and channels to identify what resonates best with your audience and drives the highest conversion rates. Testing provides valuable insights that can shape your overall strategy.

Monitor the results in real time, tracking metrics like conversion rates and customer acquisition costs. If a campaign isn’t performing, quickly reallocate funds to higher-performing initiatives. This flexible approach allows your budget to adapt to changing market conditions, maximizing ROI by scaling successful strategies and refining or discontinuing those underperforming.

5. Optimize with Automation

Most successful eCommerce businesses use automation tools to streamline marketing efforts. For example, popular platforms like Klaviyo, Marketo, and Mailchimp can automate email marketing, lead scoring, and campaign scheduling, allowing you to focus on strategy while they manage the repetitive tasks.

McKinsey highlights how AI and interconnected technologies can enhance efficiency and reduce costs in eCommerce by:

  • Automating personalized email campaigns with tools like ChatGPT
  • Scheduling social media posts based on audience activity patterns via platforms like Buffer or Hootsuite
  • Using advanced customer segmentation through predictive analytics to tailor marketing strategies for distinct audience groups

AI-driven tools can be extremely useful for optimizing ad placements and personalizing user experiences, so be sure to utilize them.

6. Choose the Right eCommerce Platform to Scale Efficiently

Your eCommerce platform is a strategic investment in your marketing infrastructure. The platform you choose will impact everything from automation potential to how easily you can integrate tools, test new strategies, and scale.

As Bradley says, some platforms like Shopify allow for plug-and-play capability out of the box, but for those requiring a more advanced feature set and tooling integrations Adobe Commerce (previously Magento) offers more freedom to scale.

Adopting a bigger picture mindset — thinking about where you need to be in six months or even five years ahead — is ideal to help determine the best path forward, and in general one size doesn’t fit all. “Don't get starry eyed with a relatively quick, low-cost start as it could be more costly down the road when you run into roadblocks or limitations and so on,” Bradley concludes.

7. Factor Seasonality and Capitalize on Shopping Events

Don’t miss the chance to capitalize on seasonal trends and major shopping events — factor them into your eCommerce store's budget strategy. Certain times of the year, like holidays and promotional events, drive increased consumer spending and are a golden opportunity to maximize sales.

For instance, Black Friday and Cyber Monday are the biggest shopping events of the year, drawing many customers looking for discounts. To stand out during these periods, create urgency with time-sensitive offers, bundle deals, or free shipping incentives.

In addition, it’s important to analyze historical data to identify seasonal patterns unique to your business.

Tailor your inventory planning, marketing campaigns, and staffing to meet increased demand. Offer special promotions, use hyper-targeted ads leveraging tools like Facebook Ads or Google Ads, and launch exclusive, limited-edition products to boost sales and optimize customer engagement during these key periods.

8. Focus on Customer Retention

Customer retention is more cost-effective than acquiring new customers and can significantly boost long-term revenue. Studies show that acquiring a new customer can cost up to seven times more than retaining an existing one. You can increase customer lifetime value and help build a loyal base that drives consistent sales with some smart retention strategies, such as:

  • Loyalty programs: Allocate part of your budget to loyalty programs that reward repeat purchases with points, discounts, or exclusive offers.
  • Personalization: Invest in personalized email campaigns to engage customers with tailored product recommendations and relevant promotions based on their past behaviors.
  • Exclusive deals: Offer exclusive deals or early access to sales for repeat buyers to make customers feel valued and encourage loyalty.

9. Regularly Review Budget Performance

Monthly or quarterly reviews are crucial for assessing budget performance and ensuring your eCommerce strategy is on track. Use KPIs like:

  • Conversion rates: Measures how well your site turns visitors into customers. Higher rates mean better marketing and user experience.
  • Return on Ad Spend (ROAS): Shows how much revenue you generate for each dollar spent on ads. A high ROAS signals effective ad campaigns.
  • Customer Acquisition Cost (CAC): Tracks the cost of acquiring a new customer. Lower CAC means more efficient use of the marketing budget.
  • Customer Lifetime Value (CLV): Calculates the total revenue from a customer over time. A higher CLV justifies more investment in acquiring new customers.

These metrics help identify which areas are performing well and which need adjustments.

By making data-driven decisions based on these insights, you can reallocate your budget, optimize underperforming campaigns, refine your strategy to maximize ROI, and stay responsive to market changes. Regular reviews will help you to fully realize the potential of your eCommerce business.

Strategic Budgeting Methods for Your eCommerce Business

You can take numerous approaches to budgeting based on your business's needs and goals. Exploring alternative budgeting strategies can ensure you maximize your resources while staying competitive. Here are some methods to consider.

Percentage-of-Revenue Approach

Allocate a set percentage of your revenue — typically 7-8% — to marketing efforts. This method ensures proportional spending based on your business’s financial health and growth stage. For newer eCommerce businesses, a higher percentage may be necessary to establish brand awareness.

Objective and Task-Based Budgeting

Identify specific marketing objectives, such as increasing website traffic by 20% or acquiring 1,000 new customers. Calculate the costs required to achieve these goals and allocate your marketing budget for eCommerce accordingly. This approach ensures alignment between spending and outcomes.

Competitive Parity Budgeting

Analyze competitors’ marketing spend to determine a baseline for your budget. You can research publicly available information, such as industry reports, competitor financials, or digital ad spending data. Tools like SpyFu can help track competitors' ad budgets and strategies.

While this method helps you remain competitive, it’s crucial to adapt based on your unique goals and resources rather than solely matching others. Tailor your budget to focus on areas where you can differentiate and achieve the highest ROI.
