With a small B2B ad budget, should I start with Google Search or LinkedIn Ads?

TofuAnswer by the Tofu team · checked

Use Google Search first if people already search for what you sell: you pay to reach buyers while they look, and clicks and leads usually cost less. Use LinkedIn first if few people search for your category, you must reach specific job titles or named accounts, and one deal is worth enough to carry leads that cost a few hundred dollars (Kiin Labs' 2026 medians: $164 to $343 per lead gen form lead). LinkedIn's Ad Tips page gives a $10 daily minimum; Google has none. On about $3,000 a month, start with one.

As of October 2026.

If you sell something buyers already search for

Start with Google Search. Check Keyword Planner for the problem you solve, not just your product name, and see whether there is real monthly volume in your country. If there is, Search reaches buyers as they look, and you pay only for clicks.

According to LocaliQ and WordStream's 2026 search advertising benchmarks (updated June 1, 2026, from thousands of their customers' Google Ads and Microsoft Ads campaigns), Business Services averaged $5.87 a click, a 4.85% conversion rate and $93.69 per lead, where a lead is any contact: a call, chat, form fill or email. There's no software category, so treat these as context.

B2B search is getting dearer. According to Dreamdata's 2026 LinkedIn Ads Benchmarks report, built on its B2B customers' data, cost per click on non-branded search terms jumped 29% and click-through rates fell 26%, and non-branded search fell from 37% of B2B ad budgets in 2024 to 33% in 2025. For the full payback test, see whether Google Ads is worth it for B2B SaaS.

If you sell in a new category that few people search for

Start with LinkedIn. If Keyword Planner shows little or no volume for the problem you solve, there's little demand for Search to capture. LinkedIn lets you choose the people instead: by job title, seniority, function, company name, industry and company size, or with an uploaded list of companies or contacts (a Matched Audience).

Expect to pay more per click and to start further from a sale, because these people weren't looking for you. Offer something worth their time, such as a guide, as well as the demo.

If you sell small deals

Start with Google Search, or wait. LinkedIn leads cost hundreds of dollars at the median:

  • According to Kiin Labs, the research panel of London LinkedIn Ads agency Kiin, the median account among 1,000+ advertisers (September 2025 to September 2026, Audience Network excluded) paid $49.98 per 1,000 single image impressions and $13.54 per landing page click.
  • In Kiin Labs' lead gen form report (489 advertisers, same period), the median lead cost $164 for a content offer and $343 for a demo request.
  • According to Metadata, a B2B ad platform, the median LinkedIn cost per lead across 88 B2B advertisers in 2025 was $376.

Work back from what a customer pays you. For example, if 1 in 10 demo requests becomes a customer (use your own rate), a $343 lead means about $3,430 in media per new customer. If a customer pays you less than that within your payback period, LinkedIn won't pay back at median costs. For what moves LinkedIn costs, see what a normal LinkedIn CPM, CPC and cost per lead look like.

If you sell large deals to a list of target accounts

Start with LinkedIn, or add it soon after Search. Upload your target companies as a Matched Audience or target them by company name, then narrow to the roles that buy.

LinkedIn looks better when you measure revenue instead of leads. According to Dreamdata's 2026 report, using its own attribution across its B2B customers, LinkedIn returned 121% on ad spend in 2025, against 67% for Google Search and 51% for Meta, and cost €70.11 per company influenced, against €110.37 on Google Search. That's one vendor's customers and one attribution method, so test with your own CRM data before you shift budget.

If you need to reach a job title, seniority or function

Use LinkedIn. LinkedIn says job title targeting uses mostly what members enter on their profiles, with some inference and no third-party data, and it maps titles to seniority and function with its own taxonomy. An ad set needs at least 300 members, and LinkedIn suggests at least 50,000 to drive results (300,000 for Sponsored Content).

Google Search targets the words people type. The detailed demographic segments listed on Google's audience segments help page include three company size bands (1 to 249, 250 to 10,000, and more than 10,000 employees) and eight industries, marked as usable on Search, but no job title, seniority or function. You can also add your own customer lists.

If you have about $3,000 a month or less

Pick one platform and give it the whole budget. What each platform states:

LinkedInGoogle Ads
Minimum$10 a day for any ad format and $100 lifetime for a new campaign, per LinkedIn's undated Ad Tips page. Its help center doesn't repeat the $10; it gives a $30 daily minimum for campaigns using Dynamic Group Budget"No minimum spending commitment"
Suggested startThe Ad Tips page suggests a default budget of $25 for new advertisers and $50 to $100 for existing ones (USD)At least 15 conversions in the last 30 days on the action you bid toward, per Google's lead generation guide
Daily overspendUp to 100% over the daily budget on a given day, but no more than 7 times the daily budget in a weekUp to 2 times the average daily budget on a given day, but never charged more than 30.4 times it in a billing period

Example only: what $3,000 a month buys at the benchmark figures above. It's arithmetic on other advertisers' medians and averages from different samples, not a forecast.

Example: $3,000 a monthGoogle Search (LocaliQ, Business Services)LinkedIn (Kiin Labs)
Cost per click$5.87$13.54 per landing page click (single image)
ClicksAbout 510About 220
Cost per lead$93.69$164 content offer, $343 demo request (lead gen forms)
LeadsAbout 32About 18 content leads, or about 9 demo requests

In the same example, split $1,500 each way and LinkedIn buys about 4 demo requests, while Google buys about 16 leads, which only just clears Google's 15-conversion guidance. That's why one platform at a time works better on a small budget.

If you have a sales cycle of months

Either can work if you bid on an early step and report on later ones. Google Ads conversion windows run from 1 to 90 days (30 by default for clicks), and Google's lead generation guide suggests bidding on an action within 7 days of the ad interaction, then uploading CRM outcomes, ideally daily. LinkedIn's windows are 1, 7, 30 or 90 days, with 90-day clicks by default; with the Conversions API or a CSV upload, some categories, including Lead and Qualified Lead, can use 180 or 365 days. So bid on the demo request and send qualified stages back from your CRM, as in how to send MQLs and SQLs from your CRM to LinkedIn. Judge the platform on pipeline after at least one sales cycle.

What to avoid

  • Splitting a small budget across both and judging each after a few weeks. Neither gets enough data to tell you much.
  • Comparing cost per lead across platforms as if the leads were the same. A Search lead was looking for you; a LinkedIn lead was interrupted. Compare qualified pipeline per dollar in your CRM.
  • Keeping placements you didn't choose. Check whether LinkedIn Audience Network is on, and whether a Google Search campaign also runs on the Display Network and search partners.
