Know exactly which ad to run next week
Sella watches your competitors’ ads and sends you exactly what to run next on WhatsApp, every week.
Or start smaller: get a free Competitor Ad Snapshot of up to 3 rivals.
You’re spending on ads. Deciding what to run is the hard part.
Turning what your competitors are doing and what your own numbers say into a campaign that works takes real marketing expertise, every single week. Most stores can’t afford that full-time, so the decision gets made late at night, or by copying whoever is loudest.
A marketing head who studies your market every day, for less than you spend on one day of ads.
Not tips. A campaign you can paste in and run.
Every week, Sella looks at what your competitors are running and what worked for you last week, and sends the audience, the message, the creative direction and the finished copy.
Every weekly brief covers six things.
None of them is left for you to work out.
- Audience
- Who to target this week and why, grounded in what your competitors are and aren’t going after.
- Message
- The one angle to lead with, and the evidence behind choosing it over the alternatives.
- Creative direction
- What the visual should show, the format, and what to avoid because a competitor already owns it.
- Finished copy
- Primary text, headline and call to action, written and ready to paste. Not a list of tips.
- Exact settings
- Objective, placements and budget split to enter in Ads Manager, so nothing is left to interpretation.
- A measurable promise
- Which of your numbers should move and by when, so the brief can be graded against reality later.
-
Ad-ready creative kits
From an approved brief, Sella composes ad images around your actual product photos, never an invented product. Several styles are generated and scored, and you get the best three. Any image that doesn’t show the same kind of product you photographed is rejected before it reaches you.
-
Mid-week competitor alerts
When a competitor launches something new between briefs, a sale, a new product, a new angle, you hear about it that week rather than when it shows up in your sales.
-
Briefs that learn
Your first brief is built from your market. From then on each brief is checked against how the last ones actually performed for you, so the advice sharpens with every week you run it.
Every brief makes a promise. We show you when it misses.
Each brief states which of your numbers should move and by when. If your goal is sales, that is growth in orders over three weeks. If it is reaching new people, it is growth in the share of new customers over eight weeks.
When the time is up, the result is computed from your numbers, not written by us, and graded plainly: met, not met, or not yet measurable. A miss is shown to you exactly as clearly as a win, because a win you can’t verify isn’t worth anything.
Set up once. A finished campaign every week after that.
Nothing to log into and no dashboard to learn. It arrives where you already work.
-
Send us your store URL
A short intake on WhatsApp or the web: what you sell, who buys it, who you compete with, and what you want your ads to do. Then one call with the founder. That is the only time we need from you.
Once -
Sella studies your market
It reads every ad your competitors are running in the public Meta Ad Library, searches the web for what they're launching, and looks at what worked for you last week.
Every day -
You get the brief on WhatsApp
A PDF with exactly what to run next: the audience, the message, the creative direction, the finished copy and the campaign settings. Email if you prefer it.
Every week -
Approve, ask for changes, or skip
One tap. If you approve, Sella builds the ad-ready creative kit from your real product photos. You paste it into Ads Manager and run it yourself.

Sella advises. You decide and run.
These are permanent design choices, not limits of an early version.
- Never touches your ad account. No Meta or Google login, no access to your budget, nothing it can switch on or off.
- Never posts for you. Nothing goes out on your social accounts or ads without you doing it yourself.
- Never invents your product. Creative is built around your own product photos and rejected if it misrepresents them.
- A person checks every brief. Every brief and creative kit is checked by a person before it reaches you.
- Your data stays in region and leaves when you do. UK and EU store data never leaves the EU; Indian and US data stays on its own regional servers. If you disconnect, you have 30 days to come back before your data is deleted.
Sella compared with the alternatives
| Option | Cost | What’s still left to you |
|---|---|---|
| An agency | $250-400+ a month | Priced for bigger brands. At SMB budgets you get a junior and a monthly report. |
| A freelancer | Varies | Hands over tactics and ad files. The thinking about what to run next is still yours. |
| ChatGPT and doing it yourself | Your evenings | Answers what you ask. It doesn’t watch your competitors, and the synthesis is still your job every week. |
| Ad spy tools | A subscription | Tools you operate yourself. You still search, compare and decide what to run. |
| Sella | Less than a day of ad budget | Watches the market continuously and hands you a finished, ready-to-run campaign every week. |
