What Is MER? The Difference Between ROAS and MER and How to Use It in Ecommerce
The strong results an ecommerce brand sees in its ad dashboards don't always show up in total sales to the same degree. ROAS in Google Ads campaigns can rise while revenue grows more slowly, or the conversion revenue Meta Ads reports can diverge from actual sales. In those cases, MER (Marketing Efficiency Ratio) divides total sales revenue by ad spend to show the overall efficiency of your budget. Alongside campaign performance, you need to track the relationship between total sales and ad spend.
November Sales in Turkey: A Seasonal Ad Budget Planning Guide
Even when the ad budget is set before the November campaigns begin, spending during the month rarely goes exactly as planned. A brand that gets more orders than expected during 11.11 may have to revisit the amount it set aside for Black Friday.

Heavy spending in the first half of the month in particular can leave a brand entering Black Friday week with less budget than expected.
How to Allocate Budget Across Google, Meta and Marketplaces: Channel-Level Budget Planning for E-Commerce
Splitting an e-commerce ad budget across Google, Meta and marketplaces takes more than assigning fixed percentages to three channels. Product margin, current demand, stock, new-customer goals and each channel's ability to turn extra spend into sales all change the split. When planning budgets by channel, the key decision should rest less on how current spend is performing and more on which channel's next budget increment will create the most economic contribution.

How to Build a Digital Marketing Report: Key KPIs and a Sample Report Structure

Why Meta Ads and Google Ads Results Don't Match Up
Seeing 180 purchases in Meta Ads, 140 conversions in Google Ads, and 220 orders in your e-commerce backend can look like a tracking error at first glance. In reality, Meta Ads and Google Ads measure the same sale using different rules, so the numbers were never meant to line up exactly.
What Are AEO and GEO? A Guide to Getting Visible in AI Search Engines
Search visibility is no longer just about your ranking position for specific keywords on Google. Systems like Google AI Overviews and AI Mode, ChatGPT Search, Microsoft Copilot, and Perplexity now draw on web sources to generate direct answers for users. AEO and GEO focus on how content gets discovered, understood, and used within these answers. Still, this shift doesn't mean an entirely new optimization discipline is replacing SEO—Google has explicitly stated that SEO fundamentals remain valid for visibility in generative AI features, with no special "AI SEO" technique required.
What Is ROAS? How to Calculate It and What Counts as a Good ROAS
ROAS is one of the core metrics used to understand how much revenue an ad budget generates. On platforms like Google Ads and Meta Ads, it makes it easy to evaluate the revenue return on spend at the campaign, ad group, or product level. But the ratio on its own doesn't explain why performance changed—the same ROAS can hide more expensive traffic, a higher conversion rate, fewer orders, or a higher average order value, so it's important to look beyond the headline number at the metrics behind it. ROAS is calculated by dividing revenue attributed to ads by ad spend: if 50,000 TRY in ad spend generated 200,000 TRY in revenue, the result is 4, meaning every 1 TRY spent produced 4 TRY in ad revenue. There's no fixed industry benchmark for a "good" ROAS—the right level depends on each business's cost and margin structure.
