How to tighten your approach to B2B demand capture

Here’s a fun fact: optimizing your bidding strategy directly for MQLs is often the fastest way to get fewer of them. Yes, you read that correctly!

At Transmission, we’ve talked a lot about how the B2B buyer journey is changing. But today, I want to look at how the search landscape and the transformational period we’re seeing across both organic and paid.

We work with a variety of B2B clients, all in various stages of their paid search maturity journey. But despite their differences, there’s one key pain point that’s shared across every brief that comes our way:

“How can we safeguard lead quality as budgets tighten?”

The premise

B2B marketers have known how to do this for years, meaning it should be pretty simple… right?

• Primary conversions actions aligned to MQL/SQL… ✅
• Values assigned to show weighted value… ✅
• Smart bidding set to optimize towards pipeline impact… ✅

You follow your process, sit back, and watch that pipeline fill up. It won’t, mind you, because it isn’t that straightforward.

Sure, having an account strategy optimized for lower down the funnel will do what it says on the tin. But value-based bidding strategies rely on consistent, scalable signal volume. Without volume, your smart bidding won’t have enough data to prioritize bids for the users who are most likely to be of market qualified caliber (let alone Sales qualified).

That’s why we help clients integrate their systems into ad platforms directly – allowing them to see the true impact of search to pipeline and revenue. This shift enables optimization beyond surface-level metrics like form fills, moving toward MQLs, SQLs, and ultimately revenue.

In several cases, we’re seeing more promising results generating qualified leads by (funnily enough) not directly optimizing towards MQLs. Remember, the user journey from form to qualified isn’t that linear.

The stages in-between

Think about…

Account creation

Lower down funnel that forms submission, alongside volume. It gives Smart Bidding enough data density to start learning early, before intent has surfaced. Low predictive power per event, but it stabilizes the algorithm while stronger signals accumulate.

Trial activation

Separates those who are only considering from your actual buyers. Someone who creates an account and never activates has told you almost nothing. Activation means invested intent.

Trial completion

The strongest pre-MQL signal, as it mirrors your best existing customers. Build a lookback cohort of trial-complete-to-SQL rates and you’ve got a proxy for pipeline value – without waiting on SQL volume to build.

Content downloads & subscribers

Weaker signals individually but valuable for breadth – keeping signal volume high across the full funnel, not just at the bottom.

All of these points are rich behavioural signals, perfect for feeding into Smart bidding algorithms (don’t forget to assign weighted values).

The fine print

Google’s own guidance recommends roughly 30+ conversions in the trailing 30 days at the campaign level before the algorithm has enough signal to bid confidently. Establishing your MQL rate % will give direction on how many conversions are needed to reach MQL targets – making it easier to strategize across the funnel.

Two such clients (a cybersecurity solutions provider and a data movement provider) took this approach after MQLs plateaued following a strategic shift toward pipeline value. Once we allowed time to calibrate – including removing bid caps so Smart Bidding could fully adjust – we began seeing incremental month-over-month improvements.

So, instead of relying solely on downstream conversions, explore expanding mid-funnel/high intent conversion actions for the purpose of feeding improved performance signals to achieve your goal.

Don’t weight by how low down the funnel a signal is. Weight by predictive likelihood to become MQL, validated against your own data.
