Hupspot Guide to Costly Google Keywords

Hubspot regularly analyzes the most expensive Google Ads keywords to reveal where advertisers spend the most and why these terms cost so much. Understanding these high-cost keywords helps marketers refine budgets, set expectations, and avoid wasting money on clicks that will never convert.

This guide translates the insights from Hubspot research on high CPC terms into practical steps you can apply to your own paid search strategy.

What Hubspot Research Reveals About Costly Keywords

The Hubspot report on expensive keywords in Google Ads exposes patterns in the industries and terms that command the highest cost-per-click (CPC). These keywords often sit at the intersection of intense competition, high customer value, and urgent user intent.

By examining these patterns, Hubspot shows that the highest CPC terms usually include:

Legal and finance queries with high lifetime value per customer
Service-based industries where one sale covers large ad budgets
Emergency or urgent needs, such as medical or repair services
Insurance and B2B categories with long contracts and high margins

These categories give clues about where Google Ads competition is the fiercest and where you must be especially strategic with your budget.

How Hubspot Classifies the Most Expensive Keywords

In its analysis, Hubspot organizes expensive keywords by theme and industry, rather than just listing random terms. This makes it easier to understand why certain phrases cost so much.

Hubspot Focus on Industry Categories

The Hubspot breakdown shows that some industries consistently pay more per click, including:

Legal: Personal injury, criminal defense, and related law terms
Insurance: Auto, health, life, and business insurance phrases
Finance: Loans, credit cards, and mortgage keywords
Healthcare: Treatments and procedures with high revenue per patient
Home services: Plumbing, HVAC, and emergency repairs

Advertisers in these verticals bid aggressively because one new client can justify the entire monthly budget.

Hubspot Insights on Intent-Driven Phrases

Hubspot notes that the most expensive keywords usually show strong purchase or conversion intent. Common markers include:

“near me” searches indicating local, immediate needs
“best” and “top” phrases from comparison shoppers ready to choose
“buy,” “hire,” or “book” terms signaling transactional intent
Specific service names, not just broad informational topics

The closer a keyword is to a final decision, the more advertisers are willing to pay for that click.

Why Hubspot Findings Matter for Your PPC Strategy

The analysis from Hubspot is not just trivia about large ad budgets; it provides a roadmap for making smarter decisions in your own Google Ads campaigns, whatever your industry.

Hubspot Perspective on Budget Planning

When you understand which terms are notoriously expensive, you can realistically plan your budget. Instead of guessing, you can:

Estimate how many clicks your budget can buy in a high-cost niche
Decide whether you should target top-tier keywords or long-tail alternatives
Allocate more funds to campaigns with the highest revenue potential

Hubspot research helps you avoid shock when you see suggested bids for extremely competitive phrases.

Hubspot Lessons for Keyword Selection

Drawing on the Hubspot list of costly keywords, you can shape your own list more intelligently:

Use expensive terms for insight, not always direct targeting.
Build related long-tail keywords that capture similar intent at lower CPC.
Combine high-CPC head terms with supporting content and remarketing.

This approach allows you to benefit from industry demand without overspending on every click.

Step-by-Step: Apply Hubspot Insights to Your Campaigns

Use this simple process to integrate what Hubspot discovered about expensive Google Ads keywords into your workflow.

1. Review the Original Hubspot Keyword List

Start by exploring the source article that lists the expensive keywords and categories. You can read it here: Hubspot analysis of the most expensive Google Ads keywords. Make note of terms and industries that overlap with your business or your clients.

2. Map Hubspot Categories to Your Offers

Next, connect the Hubspot categories to your actual offers:

Identify which high-cost categories match your products or services.
Highlight any locations where you operate that align with “near me” trends.
List out related long-tail keywords that are more specific to your niche.

This mapping ensures that you use the high-CPC keyword data in a way that reflects your real goals.

3. Build a Tiered Keyword Strategy

Using insights from Hubspot, group your keywords into tiers by cost and intent:

Tier 1: High-CPC, high-intent keywords from the Hubspot style lists.
Tier 2: Mid-range CPC terms that still show strong intent.
Tier 3: Long-tail, lower CPC keywords for volume and testing.

Allocate budget to each tier based on expected conversion value rather than just search volume.

4. Optimize Landing Pages for Expensive Clicks

Hubspot’s research implicitly underscores how costly a single click can be in some industries. To protect that spend:

Ensure each expensive keyword leads to a highly relevant landing page.
Match the ad copy closely to the search term and visitor intent.
Use clear calls-to-action and simple forms to increase conversion rate.

The goal is to convert as many of those costly clicks as possible, rather than simply chasing more traffic.

5. Monitor and Refine Using Hubspot-Style Metrics

Following the data-driven spirit of Hubspot, track:

CPC and cost per conversion by keyword tier
Conversion rate per landing page
Return on ad spend (ROAS) for each campaign

Pause or adjust expensive keywords that do not produce revenue, and reinvest into the terms that mirror the profitable patterns highlighted in the Hubspot research.

Using Additional Resources Alongside Hubspot Insights

For example, you can work with a specialist agency that understands both paid search and SEO to refine your keyword mix, ad structure, and landing page performance. One such resource is Consultevo, which focuses on performance-driven search and content strategies.
