Link Social Data to Sales: A Weekly Spreadsheet Method

TLDR: To tie social to sales, put three exports on one weekly row: posts and clicks from social, sessions and orders from your site, and revenue from your sales system. Tag every link so each order points back to a post, then compare by week with a lag of 0 to 7 days. Expect a pattern, not proof, and say so in the report.

Social reports and sales reports live in different tools, owned by different people. Social shows reach and likes. Sales shows orders and revenue. Nobody owns the line between them, so nobody draws it.

You can draw a usable version of that line in a spreadsheet in an afternoon. Here's the method, step by step, and what it can and cannot tell you.

Join on three keys: week, campaign tag and platform

Every join needs a shared column. Use these three:

• Week: Monday's date, same on every sheet
• Campaign tag: the utm_campaign value in your links
• Platform: the utm_source value (instagram, linkedin, tiktok)

If your links are not tagged, nothing else in this post works, so fix that first. One naming rule, lowercase, no spaces, written down in one place. Two people typing "Spring_Sale" and "spring-sale" split one campaign into two rows.

Pull three exports and keep them raw

Export	From	Columns you need
Social	Your publishing and analytics tool	Date, platform, post link, reach, clicks
Site	Web analytics	Week, source, campaign, sessions, orders
Sales	Shop or CRM	Week, source if known, orders, revenue

Paste each one into its own tab and never edit them. Build the summary on a fourth tab with formulas, so you can paste next week's data over the old and the summary updates.

In Mydrop, the analytics and white-label reports show per-platform post data in one place, which saves copying numbers out of each native app.

Build the weekly row and read it three ways

The summary tab has one row per week with these columns: posts published, social clicks, site sessions from social, orders from social, revenue from social.

Then read it three ways:

1. Same-week: did weeks with more clicks also have more orders?
2. Lagged: shift orders back by 3 to 7 days. Buyers rarely buy in the session where they first clicked.
3. By campaign: do the campaigns that lift clicks also lift orders, or only clicks?

A correlation column (=CORREL(...)) across 12 or more weeks gives you a rough direction. Under 8 weeks, do not trust it; the number will swing on one good week.

What a link between the two does not prove

Be plain about the limits, because finance will ask:

• Social often assists and does not close. Someone sees a post, searches your name a week later, and the order lands under "direct" or "search".
• Private sharing is invisible. Links sent in DMs and group chats lose their tags.
• Seasonality and promotions move both lines. A sale week lifts everything.

Two cheap checks cover part of the gap. Add "how did you hear about us" to checkout, and give each platform its own promo code. Neither is perfect. Together with the tagged links they give you three imperfect signals that point the same way, which is stronger than one.

Report one decision, not a dashboard

When you share the result, finish with a recommendation tied to the data: "Carousels tagged spring-sale drove more tagged orders per post than single images, so next month's budget moves toward carousels". One sentence, one move.

Avoid reporting every column. A shorter report that changes a decision is worth more than a long one that does not. If you are still choosing what to put in it, the attribution dashboard in Google Sheets shows a ready layout, and when to replace engagement metrics with revenue explains the switch.

For context on what normal engagement looks like before you read sales into it, the Mydrop social media benchmarks list median rates by platform. In Mydrop's data, the median Instagram post earned a 3.1% engagement rate, so a post at 2% is ordinary.

Do the first join on last month's data

Tag next week's links today. Then take last month's three exports, build the weekly row, and look at the lagged view. Even with no tags in the old data, the same-week column shows whether social weeks and sales weeks move together. When you want social data in one place for that first export, start free on Mydrop.
