Average Conversion Rate by Keyword Length
Each row shows the average conversion rate for keywords of that length, with an example search.
| Keyword length | Example search | Organic conversion rate | Google Ads conversion rate |
|---|---|---|---|
| 1 word | dentist | 5.81% | 4.96% |
| 2 words | payroll software | 8.35% | 6.43% |
| 3 words | women’s running shoes | 8.24% | 6.13% |
| 4 words | small business loan rates | 9.40% | 6.89% |
| 5 words | payroll software for small business | 9.64% | 7.24% |
| 6 words | personal injury lawyer in los angeles | 7.98% | 5.89% |
| 7+ words | how long does it take to get a business loan | 8.29% | 6.07% |
| All keywords | 8.64% | 6.46% |
Key findings:
- Keywords of five or more words get about 10 times fewer searches than keywords of one to three words.
- Five-word keywords convert at 9.64% in organic search, the highest of any length.
- Conversion rate drops at six words and up. Question searches average 7.03 words and convert 45.0% below average.
Our read on this: five words is usually where a searcher has named the product, the qualifier and the place. Add a sixth word and the search tends to turn into a question, and people asking questions want an answer more than a provider.
Conversion Rate by Keyword Qualifier
One qualifier word can raise or lower conversion rate more than added length does.
| Search includes | Example search | Organic conversion rate | Google Ads conversion rate | Change versus average |
|---|---|---|---|---|
| “Emergency” or “same day” | emergency vet | 17.33% | 15.20% | +81.8% |
| A provider name | estate planning attorney | 10.71% | 8.92% | +25.9% |
| A city or state | dermatologist austin tx | 10.35% | 7.55% | +16.7% |
| “Install” or “replace” | windshield replacement | 9.58% | 7.94% | +7.9% |
| “Company” or “contractor” | payroll company | 12.30% | 9.52% | +6.0% |
| “Service” or “services” | bookkeeping services | 9.18% | 6.83% | +1.8% |
| “Near me” | urgent care near me | 7.34% | 5.55% | -17.6% |
| “Appointment” or “book” | book eye exam | 6.31% | 4.56% | -21.6% |
| “Repair” or “fix” | iphone screen repair | 6.96% | 5.78% | -27.1% |
| “Best” or “top” | best crm for startups | 4.81% | 4.30% | -34.1% |
| A question word | how does a 401k work | 4.91% | 3.37% | -45.0% |
| “Cost,” “price” or “quote” | business insurance quote | 3.92% | 3.13% | -53.2% |
Key findings:
- “Emergency” and “same day” raise conversion rate 81.8%, more than any other qualifier.
- Price words lower conversion rate 53.2%.
- A city or state name raises conversion rate 16.7%, while “near me” lowers it 17.6%.
The most likely explanation is that many “near me” searchers call straight from the Google map listing, so the conversion never shows up on the website. People who type a city name are more often planning ahead, and they read the site before they reach out.

The conversion lift from longer keywords ranges from a 14.4% drop in medical aesthetics to an 80.2% gain in legal services.

| Research | 4 to 5 words | 5.57% | 4.50% |
| Research | 6+ words | 4.59% | 3.35% |
Key findings:

LLM Conversion Rates: AI Assistant Visitors
- Visitors sent by large language model (LLM) assistants such as ChatGPT convert at 9.55%, 10.6% higher than organic search visitors.
- AI assistants send 1.17 visits for every 100 organic search visits.
Conversion Rate by AI Assistant
Conversion rate ranges from 2.48% to 12.06% by assistant. ChatGPT sends the most AI visits and converts highest.
| AI assistant | Conversion rate, 2026 | Versus organic search | Share of AI visits |
|---|---|---|---|
| ChatGPT | 12.06% | +39.7% | 65.90% |
| Microsoft Copilot | 9.21% | +6.7% | 4.11% |
| Claude | 6.89% | -20.2% | 5.42% |
| Perplexity | 4.33% | -49.8% | 12.78% |
| Gemini | 2.48% | -71.3% | 11.80% |
| All AI assistants | 9.55% | +10.6% | 100.00% |
Key findings:
- ChatGPT visitors convert at 12.06%, almost five times the 2.48% rate for Gemini visitors.
- ChatGPT sends 65.90% of all AI assistant visits.
- Microsoft Copilot visitors convert at 9.21%, above the organic average but 23.6% below ChatGPT.
We think the difference between assistants comes down to where each one shows up and who’s using it. ChatGPT users often ask outright for a recommendation, so ChatGPT does the comparing and sends a visitor who’s ready to act. Copilot is built into Microsoft 365 and Bing, where a lot of users are at work checking a fact for a task. Gemini answers show up inside Google’s own apps, where a click is often a quick source check.
LLM Conversion Rate by Search Type
AI assistant visitors convert higher than organic and paid visitors for every search type.
| Search type | AI assistant conversion rate | Organic conversion rate | Google Ads conversion rate |
|---|---|---|---|
| Transactional | 11.56% | 10.45% | 8.18% |
| No qualifier | 9.24% | 8.35% | 6.14% |
| Research | 5.49% | 4.96% | 3.90% |
| All searches | 9.55% | 8.64% | 6.46% |
AI Prompt Length vs. Keyword Length
- ChatGPT prompts that trigger a web search averaged 8.7 words in early 2026, up from 4.7 words a year earlier.
- The average Google keyword is 1.9 words long.
- The average non-brand Google Ads search is 3.6 words long.
An 8.7-word prompt has about as much detail as a long-tail keyword, and we think that’s why AI visitors convert like long-tail searchers.
Google Ads Cost per Conversion by Keyword Length
- One-word keywords cost $236.98 per conversion. Keywords of seven or more words cost $70.08, 70.4% less.
- The average cost per click falls from $11.76 at one word to $4.25 at seven or more words, because fewer advertisers bid on long keywords.
What a Good Conversion Rate Looks Like by Keyword Length
- One to two words: 5.81% to 8.35% organic, 4.96% to 6.43% in Google Ads
- Three to five words: 8.24% to 9.64% organic, 6.13% to 7.24% in Google Ads
- Six words or more: 7.98% to 8.29% organic, 5.89% to 6.07% in Google Ads
The median Google Ads conversion rate across all searches, brand searches included, is 7.52%. Each benchmark above assumes the searcher reaches a page built for that exact search.
How These Figures Are Calculated
- Conversion rate = conversions ÷ clicks (paid) or sessions (organic and AI) × 100
- Change versus average = a qualifier’s conversion rate ÷ the same advertiser’s average conversion rate, minus 1
- Cost per conversion = ad spend ÷ conversions
All figures exclude searches that contain the advertiser’s own brand name.
