Your first-time customer products are some of the most important assets in ecommerce. If those products are out of stock, Meta ads, Google Shopping and new customer recruitment can collapse quickly. Prioritise the stock that brings new buyers into the business.

[Mark Hammersley @hammersley]

You need to put a dollar value on ecommerce stock gaps. Out-of-stock products do not just reduce sales, they damage conversion, customer acquisition, ROAS and marketing efficiency. Show the revenue loss so stock planning gets treated like a growth lever.

[Mark Hammersley @hammersley]

Ecommerce customers won’t wait like shoppers in the only store in town. If a product is out of stock, they leave in one click, hurting conversion rates, ROAS, and customer acquisition. Online stock planning isn’t warehouse admin, it’s marketing strategy.

[Mark Hammersley @hammersley]

Stock issues can quietly destroy ecommerce ROAS before the ad account gets blamed. If your key products are out of stock, Meta ads, Google Shopping and conversion rate will all feel the hit. Know which products actually drive revenue before you push more spend.

[Mark Hammersley @hammersley]

A small number of products drive most ecommerce revenue. Online stores don’t need endless choice like retail shops. Double down on your best sellers to increase conversion and scale profitably.

[Mark Hammersley @hammersley]

Too many products dilute your ad performance. Google needs data to optimise and spread budgets kill that. Reduce SKU focus to improve ROAS and scale Meta and Google ads faster.

[Mark Hammersley @hammersley]

Most revenue comes from a small number of products so stock matters more than range. Running out of best sellers kills conversion and ROAS. Prioritise inventory on your highest performing SKUs to scale ecommerce revenue.

[Mark Hammersley @hammersley]

Scaling ecommerce comes from focus not diversification. Master a few products before expanding your range. Specialisation improves conversion rate, ads performance and profitability.

[Mark Hammersley @hammersley]

Adding more products does not equal more ecommerce sales. Growth comes from product mix and conversion not SKU count. Focus on what actually drives revenue before scaling your catalogue.

[Mark Hammersley @hammersley]

Adding new product categories can hurt more than help. Complexity confuses customers and ad platforms like Meta and Google. Focus your ecommerce offer before expanding into new categories.

[Mark Hammersley @hammersley]

Follow-up increases conversion rate which directly drives ROAS. Email and remarketing amplify ad performance and unlock scaling. Build a strong ecommerce follow-up system before increasing ad spend.

Most ecommerce founders stay stuck chasing shiny objects. This week on the Hammersley Brothers Ecommerce Podcast, we break down the mindset traps killing growth, why boring fundamentals win, and what actually separates scalable brands from the rest.

Email is the highest ROI channel in ecommerce because you are marketing to warm buyers. Most brands focus on flows instead of fixing low email capture rates. Increase email capture first if you want better conversion rate and lower ad costs.

[Mark Hammersley @hammersley]

Timing matters more than most ecommerce brands realise. Sending emails when users are active can double conversion rates. Optimise send times to improve ROAS and maximise marketing performance.

[Mark Hammersley @hammersley]

Most ecommerce brands optimise email flows instead of fixing data capture. More emails means more revenue even with average campaigns. Focus on fundamentals like email capture before chasing advanced marketing tactics.

[Mark Hammersley @hammersley]

Customers don’t abandon because of price or shipping most of the time. They just are not sure yet. Follow-up marketing targets almost buyers and turns hesitation into conversion.

[Mark Hammersley @hammersley]

People assume ads should convert instantly but ignore what happens after the click. Conversion rate is driven by what happens between first click and purchase. Fix your ecommerce follow-up strategy if you want better ROAS and scalable ads.
