Meta descriptions

The meta description is the 155-character snippet that shows up under the blue title on a Google result. It's not a direct ranking factor. Google has said so explicitly. But it drives click-through rate, and click-through rate drives both revenue and rankings over time. This page walks through what a great meta description does, the length rules, the patterns that actually get clicks, and why Google rewrites most of them anyway.

The mindset: your second pitch

The user's brain scans your SERP listing in about 0.3 seconds. Title first, description second, URL third. If the title survives the scan, the description seals the deal. Think of it as your follow-up sentence after a strong opener. It has to promise enough specific value to get the click.

Most sites write meta descriptions like they're a box to check. "Learn everything you need to know about CRM for insurance agents!" says nothing. No click-worthy promise, no differentiation, no reason to pick you over the other nine results on the page.

What a meta description actually does

The length rules

• Target 150 to 160 characters. That's about 2 short sentences or 1 medium one.
• Under 120 looks thin. Google may ignore yours and generate its own from your body text.
• Over 160 truncates. The back half gets cut with an ellipsis. Put the pitch up front so the truncation doesn't eat your hook.
• Mobile is shorter. Mobile SERPs truncate around 120 characters. The opening half matters most.

What to include

1. The one sentence that summarizes the page's unique value. Not generic value. Specific to this page.
2. A benefit or differentiator. Free, comprehensive, 2026 data, expert-reviewed, step-by-step, includes templates.
3. A subtle call to action. "Learn how," "See the full guide," "Find out why." Doesn't have to shout.
4. The primary keyword, naturally used. Google bolds matching query terms in the SERP, which catches the eye. Don't stuff, just include once.

Patterns that work

What not to do

• Don't copy your title. Redundant and wastes the second pitch.
• Don't generalize. "Learn everything you need to know" tells the reader nothing.
• Don't lie. If the page doesn't deliver what the description promises, you get bounces. Bounces hurt rankings over time.
• Don't skip it entirely. Google will invent one from your body text. Usually worse than what you'd write.
• Don't keyword-stuff. It doesn't help ranking (not a signal) and hurts CTR when it reads robotic.

Why Google rewrites most meta descriptions

Roughly 60 to 70% of meta descriptions get rewritten by Google in the actual SERP. Usually it picks a sentence from your page body that matches the specific query better than your meta did.

You can't stop this. You can reduce it. Two things help. First, write a meta description that directly addresses the query you want to rank for. Second, make sure the body of your page also contains that language so Google has good on-page options to pull from if it decides to rewrite.

Practically: if your page ranks for 20 different queries, Google will show 20 different descriptions depending on who's searching what. Your job is to write the best default, then trust Google to adapt for specific queries.

The CTR testing loop

This is where the real money lives. Meta description iteration is almost free and can move your clicks significantly.

1. Open Google Search Console
2. Filter to pages ranking in positions 3 to 10
3. Sort by impressions (high traffic, middle ranking)
4. Find pages with below-average CTR for their position
5. Rewrite the title and meta description with sharper promises
6. Wait 2 weeks. Check CTR again.
7. Keep what works, revert what doesn't, iterate

The average position is roughly: #3 gets 10% CTR, #5 gets 6%, #10 gets 2.5%. If you're at position 5 with 3% CTR, you're leaving clicks on the table. That's a meta description and title problem.

What to do with this

Pick your 10 top-traffic pages right now. Open each one. Read the meta description out loud. Ask yourself honestly whether it would make you click if you saw it on a busy results page. If not, rewrite it. This is 20 minutes of work that can compound into thousands of extra clicks per month.
