Google Ads for B2B SaaS nearly always breaks in the same place: what you tell Google counts as a conversion. Optimize toward free signups or ebook downloads and the algorithm finds people who sign up, which in B2B means students, competitors and the curious.
What Google captures in B2B
Search captures existing demand, in four forms: your brand; alternatives and comparisons (“[competitor] alternative”); the category with buying intent (“invoicing software for small business”); and the problem, high volume and low intent, usually better served by content. If nobody searches your category yet, demand has to be created elsewhere first; see early-stage startup growth.
The conversion: from signup to opportunity
Start with demo requests or signups as primary. Once there are a few dozen a month, import qualified demos or opportunities from the CRM as offline conversions (via GCLID or enhanced conversions for leads) and make them primary. Later, import contract value. With cycles of weeks or months, extend the conversion window. Full logic in Google Ads lead quality.
Competitor keywords
Bidding on a competitor’s name as a keyword is generally allowed; using their trademark in ad text is more restricted depending on country and brand. Expect high CPCs and low conversion rates (many searchers want the competitor’s login), send traffic to an honest comparison page, and judge by opportunities, not clicks.
Structure and budget
Separate brand from non-brand, keep few campaigns with enough volume each, and be careful with Performance Max without a quality conversion; see Performance Max: when it works. Budget math is in how much Google Ads costs.
When to add LinkedIn
Google finds people who search; LinkedIn lets you choose who you talk to by role, industry and company size. Add it when category search is thin, the buyer is very specific, or for remarketing to visiting accounts. It costs more per click, so on a small budget start with Google if there is demand to capture.
Measure what matters
Cost per opportunity and per customer, by campaign, against what a customer is worth; see LTV and CAC together. Long journeys make last click overstate brand; see what is last-touch attribution.
