Meta descriptions are the preview text under your title in Google results. Bryan Collins explains what meta descriptions are, how they affect CTR, and how to write effective ones.
A meta description is the brief text that appears below your page title in Google search results. It’s the second thing searchers read after your title — and it’s often the deciding factor between clicking your result or a competitor’s.
After 30 years in SEO, here’s everything you need to know about meta descriptions.
What a Meta Description Is
In your page’s HTML, a meta description looks like:
<meta name="description" content="NJ licensed plumber serving Piscataway and Middlesex County. Emergency plumbing, drain cleaning, and water heater service. Free estimates — call (732) 555-0100.">
In Google search results, it appears as the gray text below the blue clickable title:
Collins Plumbing | Piscataway, NJ Plumber
NJ licensed plumber serving Piscataway and Middlesex County. Emergency
plumbing, drain cleaning, and water heater service. Free estimates — call
(732) 555-0100.
Meta Descriptions Are Not a Ranking Factor
Google has explicitly confirmed that meta descriptions do not affect page rankings. The algorithm doesn’t use meta description content when deciding where to rank a page.
Why they still matter: Meta descriptions affect click-through rate (CTR) — how many searchers click your result when it appears. A compelling meta description gets more clicks from the same ranking position, which means:
- More organic traffic without changing your rankings
- Higher visitor volume from the same keyword positions
- Potentially positive user engagement signals to Google over time
A well-written meta description is like a 155-character advertisement for your page.
How Long Should a Meta Description Be?
Target: 140–155 characters (including spaces)
Google truncates descriptions longer than approximately 155–160 characters with ”…” in desktop results. On mobile, the cutoff is around 120 characters.
The consequence of being too long: Your description gets cut off mid-sentence, which looks unprofessional and loses your call to action if it was at the end.
The consequence of being too short: You’re leaving available SERP real estate unused — each character is an opportunity to sell the click.
Use an online character counter or a tool like Yoast SEO (for WordPress) that shows the character count as you type.
Will Google Show Your Meta Description?
Not always — Google rewrites or replaces meta descriptions approximately 60–70% of the time for informational queries where it believes a different page excerpt better matches the search intent.
For commercial and local searches (service queries, branded searches, “near me” searches), your written meta description is more likely to be shown.
Implication: Write the best meta description you can — Google will use it when it’s the best option. When Google rewrites it, it typically uses a passage from your page that it believes better answers the query.
What Makes a Good Meta Description
1. Include the primary keyword naturally
When a searcher’s query matches words in the meta description, Google bolds those words in the result — making your listing stand out visually.
If someone searches “NJ plumber Piscataway” and your description contains those words, they’ll be bolded and immediately catch the eye.
2. State a clear value proposition
What makes your service or content worth clicking? Examples:
- “NJ licensed, 30+ years in Middlesex County”
- “Free same-day estimates — no call-out fee”
- “Updated for 2026 — NJ-specific examples throughout”
- “Includes cost calculator and what to expect from the first visit”
3. Match the search intent
The description should accurately preview what the searcher will find. Misalignment (promising content that isn’t there) increases bounce rate.
4. Include a call to action
For service pages: “Call us today,” “Get a free estimate,” “Book online in 60 seconds.” For content pages: “Read the complete guide,” “Get the step-by-step breakdown,” “See exact NJ examples.”
5. Be unique on every page
Each page needs a description specific to that page’s content and target keyword. Duplicate descriptions waste the opportunity and may flag thin/duplicate content to Google.
Examples: Bad vs. Good Meta Descriptions
Bad (no keyword, no value, no CTA, unclear): “Welcome to Collins Plumbing. We are a plumbing company serving New Jersey homeowners with quality plumbing services.”
Good (keyword included, value stated, CTA present, within limit): “NJ licensed plumber serving Piscataway and Middlesex County. Emergency plumbing, drain cleaning & water heaters. Free estimates — call 24/7.” (152 characters)
Bad (too generic, no local relevance, no differentiator): “Learn about SEO for local businesses. Read our complete guide to SEO.”
Good (benefit-focused, specific, signals content quality): “30 years of local SEO experience applied to NJ businesses. Includes real examples from Middlesex County clients and a free audit checklist.” (141 characters)

Frequently Asked Questions
What is a meta description? A meta description is an HTML attribute that provides a brief summary of a web page’s content. It appears in Google search results as the descriptive text beneath the clickable blue title link. While Google doesn’t use meta descriptions as a direct ranking factor, they influence click-through rate — how many people click your result vs. competitors’ results.
Does a meta description affect Google rankings? Meta descriptions are not a direct Google ranking factor. However, they indirectly affect SEO through click-through rate: a compelling meta description gets more clicks from the same ranking position. Higher CTR means more organic traffic without improving rankings.
How long should a meta description be? Meta descriptions should be 140–160 characters (including spaces). Google typically displays up to ~155–160 characters on desktop before truncating with ’…’ Descriptions over 160 characters get cut off mid-sentence.
Will Google always show my meta description? No — Google rewrites meta descriptions approximately 60–70% of the time, especially for informational queries. For commercial/navigational searches (local business queries, branded searches), your written meta description is more likely to be shown.
What makes a good meta description? Good meta descriptions: include the primary keyword naturally, state a clear benefit or unique value proposition, match the intent of the search query, include a call to action, are 140–155 characters, and are unique on every page.
Should every page have a unique meta description? Yes — every page should have a unique meta description specific to that page’s content and target keyword. Duplicate meta descriptions indicate to Google that content may be thin or duplicated, and waste the opportunity to tailor the SERP snippet to each page’s specific audience and value proposition.
How do I check my current meta descriptions? Methods: Google Search Console → Enhancements → On-Page Basics, Screaming Frog web crawler (crawls and exports all meta descriptions), view page source in your browser (right-click → View Page Source → Ctrl+F ‘meta name=description’), or search your target keyword and see what description currently appears.
