Small B2B Companies Are Usually Running the Wrong Channel

LinkedIn has the best B2B targeting available anywhere and the highest cost per click of any channel — often several times what the same click costs on Google. So most small B2B companies do the obvious thing, spend $2,000 on LinkedIn, get eleven leads of uncertain quality, and conclude that paid media doesn't work for them.

There's usually a cheaper route to the same buyer, and almost nobody mentions it because it isn't glamorous.

The channel nobody suggests

Microsoft owns LinkedIn, and you can layer LinkedIn profile data onto Microsoft Ads search campaigns.

That means bidding more aggressively when the person searching works at a company in your target industry, holds a particular job function, or works somewhere of a certain size — combined with the fact that they're actively searching for what you sell.

Google can't do this. LinkedIn can do the firmographic half but not the intent half. This is the only place both exist together, and the clicks cost a fraction of LinkedIn's.

The minimum spend is $500 a month, the lowest of any channel, which makes it inexpensive to find out.

	LinkedIn	Microsoft Ads
Firmographic targeting	Best available	Same data, layered on search
Search intent	None — you interrupt	Yes — they're looking
Cost per click	Highest of any channel	A fraction of it
Practical floor	~$2,000/mo for 90 days	$500/mo
Volume	Limited by budget	Limited by search volume, which is thin

The honest catch: Microsoft's search volume is small. Expect perhaps 10–20% of the traffic Google would give you. It's incremental, not a whole programme — and for a B2B company with a $15,000 average deal, incremental at low cost is a good trade.

When LinkedIn genuinely is right

Four conditions, and all four need to be true:

You sell to businesses. Obviously
Your customer is worth $10,000 or more. Below that the click costs don't pay back
You can define the buyer precisely — job title, industry, company size. Vague targeting burns budget faster here than anywhere
You can commit $2,000+ a month for 90 days. B2B cycles outlast short tests

Miss one and choose something else. Full detail on the channel, including the one thing it does that nothing else does — uploading a list of target accounts and advertising only to people who work there.

The mistake underneath the channel mistake

Advertising a demo to people who've never heard of you.

B2B buyers at the top of the funnel are researching, not buying. "Book a demo" is an enormous ask from someone who learned you exist ninety seconds ago, and it's what most small B2B companies put in their ads because it's what they want.

What works instead: original research, benchmark reports, buyer's guides, comparison content, implementation detail — the material someone needs to build an internal case. Because they will have to build one.

The committee nobody accounts for

A B2B purchase is rarely one person's decision, and small companies market as though it is.

Who	What they need
The user	Will this make my week better?
Their manager	Will this work, and who else uses it?
Finance	What does it cost and what's the return?
IT or security	Is it safe and does it integrate?
Your champion	Something they can forward internally without explaining

That last row is the practical one. Your best content is the thing your champion sends to their boss. If everything you produce is a landing page with a demo form, you've given them nothing to forward — and the conversation stops in an inbox you can't see.

What we'd actually do

Start with content and AI search visibility. B2B buyers research heavily before contacting anyone, and increasingly that research runs through AI assistants. Being the source that gets cited is worth more than being the ad that gets skipped.

Add Microsoft Ads with LinkedIn profile targeting. Cheap, high intent, and genuinely differentiated.

Add Google Ads for the terms with real commercial intent, accepting that B2B search volume is thin.

Consider LinkedIn last, and only against the four conditions. Retarget before you prospect — reaching people who already visited your site is dramatically cheaper than reaching strangers, and it's where most LinkedIn budgets should start.

Fix attribution before any of it. B2B cycles run months, so last-click will credit whatever came last and starve everything that did the early work. Tracking and attribution covers it.
