case study

revenue up 175%, led by two hero sharpeners

Sharp Pebble sells sharpening tools on its own store and on Amazon. Two products made the year: the chainsaw sharpener and the lawn mower blade sharpener. We put them at the centre of the account, rebuilt their creative around the problems owners notice long before they shop, then fixed the pages those ads land on.

the problem

Nobody wakes up wanting a sharpener. People notice a chainsaw that chews and smokes instead of cutting, or a lawn that looks torn after mowing, and most of them buy a new chain, a new blade or pay a shop to fix it.

Ads that demonstrate the tool and its angle settings only speak to the small group already shopping for one.

the call

back two heroes, sell the symptom

We concentrated the account on the chainsaw sharpener and the lawn mower sharpener, and built their creative around the moment before anyone searches: the chain that chews through a log, the ragged lawn, the bill from the sharpening shop. That reaches the much larger group who have the problem but aren't in the market yet.

Each hero got its own creative stream and its own landing page, so a lawn owner and a chainsaw user each see an ad and a page about their problem. Bundles lifted order value so the extra reach paid its way.

why it works

Brands grow by linking themselves to more of the situations that trigger a purchase, the category entry points (Romaniuk, Better Brand Health).

what we did

creative at volume, two hero streams

Separate streams of creator UGC, demonstrations and statics for the chainsaw sharpener and the lawn mower sharpener, tested in a structured Meta account and scaled on results.

search & youtube to catch the demand

Google Shopping and Search, tightened with search-term mining and exclusions, plus YouTube for longer demonstrations that answer 'will it work on mine?'

product pages that answer fit questions

Pages redesigned around compatibility, ease of use and proof, so a shopper can confirm the sharpener suits their chain or mower blade without leaving the page.

bundles that lift order value

Bundles and add-ons gave buyers a reason to spend more per order, which funds more top-of-funnel reach.
