Title tags and meta descriptions are the first thing searchers see of your page, and writing them well is one of the quickest on-page SEO wins.
The title tag and meta description are the first things most people see of your page, because they often appear in search results before anyone clicks. They're also among the easiest SEO elements to improve. This guide explains what each one does, how long they should be and how to write them well. Smart SEO Scanner checks both on any page you scan.
Writing meta descriptions for mobile searchers
Most people will read your snippet on a phone. The Pew Research Center reports that 91% of U.S. adults own a smartphone. Mobile result snippets can be cut shorter than desktop ones, so put the most useful words near the start of both the title and the meta description.
What the title tag does
The title tag is the text inside the <title> element in your page's HTML. Browsers show it in the tab, and search engines commonly use it as the clickable headline in search results.
It does two jobs:
Tells search engines what the page is about. It's one of the clearest signals on the page.
Convinces people to click. In a list of results, a clear and relevant title stands out.
Search engines sometimes rewrite titles they think don't describe the page well. The best way to avoid that is to write an accurate title in the first place.
How to write a good title tag
Put the main topic first. People scan the beginning of titles. "Emergency Plumber in Austin | Smith Plumbing" is clearer than "Smith Plumbing – Home | Services | Emergency Plumber Austin".
Be specific. "Chocolate Chip Cookie Recipe (Chewy, One Bowl)" tells the reader exactly what they'll get.
Make every title unique. Each page on your site should have its own title. Duplicate titles make it harder for search engines to tell pages apart.
Include your brand when it helps, usually at the end, separated by a dash or pipe.
Keep it reasonably short. Search results cut off long titles. Around 50 to 60 characters usually displays in full, although the exact cutoff depends on character widths and the device.
Titles that say nothing: "Home", "Untitled", "Page 1"
All caps
What the meta description does
The meta description is a short summary in the page's HTML. Search engines often show it under the title in search results, although they sometimes choose other text from the page if they think it matches the search better.
The meta description isn't a direct ranking factor for Google, but it strongly affects whether people click. Think of it as the small advert for your page.
How to write a good meta description
Summarize what the page offers. What will the visitor find or be able to do?
Match the search intent. If people searching for this topic want a how-to, say it's a step-by-step guide.
Include the main topic naturally. Search engines often highlight words that match the query.
Be specific and concrete. "Learn how to fix a leaky faucet in 20 minutes with basic tools" beats "We offer great plumbing information".
Keep it to roughly 150 to 160 characters. Longer descriptions are usually cut off with an ellipsis.
Make it unique for each page.
Examples: before and after
Local service page
Before title: "Services"
After title: "Lawn Care and Mowing in Boise | Green Acre Lawns"
Before description: "Welcome to our website."
After description: "Weekly mowing, edging and seasonal lawn care for homes across Boise. See service areas and request a free quote online in a couple of minutes."
Blog article
Before title: "Blog Post 14"
After title: "How to Repot a Snake Plant Without Hurting the Roots"
After description: "A simple guide to repotting a snake plant: when to do it, which pot and soil to use, and how to handle the roots so the plant settles in quickly."
Product page
Before title: "Product"
After title: "Waxed Canvas Tote Bag – Water Resistant | Northline Goods"
After description: "A sturdy waxed canvas tote with leather handles and an inside pocket. Water resistant, easy to clean and big enough for a laptop and groceries."
Common mistakes the scanner catches
When you scan a page, the report flags:
Missing title or description. Every indexable page should have both.
Too short or too long. Very short titles waste space; very long ones get cut off.
Missing keywords or mismatched topics. The report shows how your title, description and headings relate, which helps you spot pages where they talk about different things.
How to change titles and descriptions
Where you edit these depends on your platform:
WordPress: most SEO plugins add title and description fields to each page and post.
Shopify, Wix, Squarespace and similar builders: look for "SEO" or "search engine listing" settings on each page or product.
Custom sites: edit the <title> and <meta name="description"> tags in the page template.
After making changes, re-scan the page to confirm the new tags are live. Search engines will pick up the change the next time they crawl the page, which can take anywhere from days to weeks.
Quick checklist
One unique title per page, main topic first
Brand at the end if useful
Title roughly 50–60 characters
One unique meta description per page
Description roughly 150–160 characters, specific and accurate
