"Just use revenue per click on every keyword to set your bids."

"Just use revenue per click on every keyword to set your bids."

Sounds clean.

Until you run it on a keyword with ONE click and ONE sale 👇

Here's what happens:

You spent $1 on that click. It made $20 in sales.

So your revenue per click is $20.

Multiply that by a 30% target ACOS and the formula tells you to bid... $6.

On a keyword you know almost nothing about.

That's not a bid. That's a wild guess with a decimal point.

One click, one sale means near-zero data confidence. The formula assumes that $20 RPC holds. It won't. Over more clicks, performance actualizes and that number comes crashing back to earth.

So RPC is 𝗻𝗼𝘁 how we increase bids on low-data keywords.

We use it for the 𝗼𝗽𝗽𝗼𝘀𝗶𝘁𝗲 job - 𝗿𝗲𝗱𝘂𝗰𝗶𝗻𝗴 ACOS on high-ACOS or high-spend, non-converting keywords.

And there's one exception where one click, one sale IS enough:

🔸 If that keyword is already 𝗼𝘃𝗲𝗿𝘀𝗵𝗼𝗼𝘁𝗶𝗻𝗴 your target ACOS at 100% conversion, you're way over. That's plenty of confidence to start pulling the bid DOWN.

But increasing? Different game entirely.

Here's the danger:

🔹 Jack the bid on an auto or broad keyword and you don't just bid more - you open yourself up to a whole new echelon of search terms you were never competing in. Unpredictable performance. Spend spikes out of nowhere.

So for low-ACOS, one-click, one-sale keywords, we don't skyrocket to the RPC bid.

We use RPC as a 𝗯𝗶𝗱 𝗰𝗲𝗶𝗹𝗶𝗻𝗴 - the max we won't overshoot - then step the bid up 5, 10, 15% at a time.

Stepladder, not rocket ship.
