How to Write a Meta Description | CTR-Boosting Phrasing and Length Guidelines

A meta description doesn't directly affect search rankings, but it strongly influences whether users click through from the search results (the CTR). Even at the same ranking position, the number of visitors can change depending on how the description is written. This article organizes, on a practical basis, how to write meta descriptions that raise CTR, covering the character-count guidelines to keep in mind, the knack for wording that gets clicks, and the NG patterns to avoid.

The relationship between meta descriptions and CTR

A meta description is the summary of a page's content displayed beneath the title and URL in the search results. You set it with the HTML meta tag (name="description"). Google does not use it as a direct ranking factor for search position, but search users read this description to judge whether what they want to know is written there, and decide whether to click.

In other words, even at the same position, an appealing description raises the click-through rate and, as a result, increases visits. This is why it's worth putting effort into how you write it. Below, we look at the specific points.

Character-count guidelines for meta descriptions

A meta description is truncated with an ellipsis where it exceeds the displayable width. The number of characters that can be shown varies by device, and is shorter on smartphones than on PCs. As of 2026, the guidelines are as follows.

Smartphone: roughly the first 60 to 70 full-width characters are shown
PC: roughly the first 120 full-width characters are shown (though this has been shrinking in recent years)

Because Google manages the display range by pixel width, character counts are only a guide. Also, since a large share of searches in Japan are done on smartphones, it's safe to design around the smartphone display.

A practical recommendation is to condense the most important information and keywords into the first 60 characters, and keep the whole to around 120 characters. That way, even if the latter half is truncated on a smartphone, what you want to convey still gets across, and it doesn't feel off even when displayed at full length on a PC.

The knack for writing that raises CTR

Just keeping to the character count won't increase clicks. Here are concrete tips for wording that makes the reader want to open the page.

Put the target keyword in the first half

Words that match the search keyword are shown in bold within the snippet. If you naturally include the keyword you're targeting in the first half of the description, that part becomes bold, draws the user's eye, and helps improve CTR. That said, stuffing is counterproductive, so keep it within the bounds of natural writing.

Write the answer to the search intent first

Users judge in an instant whether a page will answer their question. State concisely in the first sentence what they'll understand or be able to do by reading the page. Since the first half is the part shown without being truncated, placing the conclusion or benefit here is effective.

Include concrete numbers and features

Just saying "explained in detail" won't differentiate you from other pages. Adding concrete numbers, targets, or features, such as a number of steps, doable in a number of minutes, or beginner-friendly, conveys the outline of the content and makes it more likely to be clicked. The premise is that this is concreteness in line with the actual page content, not exaggeration.

Add a phrase that prompts action

Adding a short phrase at the end of the description, such as "start with the basics" or "explained with a template," makes it easier for the reader to picture the next action. Avoid excessive hype, but a light nudge that points to the reader's benefit is effective.

NG ways of writing to avoid

Conversely, there are ways of writing that tend to lower CTR or get rewritten by Google. Avoid the following patterns.

Reusing the same description on every page: the content of each page doesn't come across, and it gives an impression of duplicate content
Listing keywords unnaturally: it can't be read as prose, and is valued by neither users nor Google
Content that contradicts the body: after clicking, users feel it was different and leave, which actually lowers your evaluation
Leaving it blank: Google auto-generates from the body, but you can't make the intended pitch

Note that even if you set a meta description, Google may rewrite the display by extracting part of the body in response to the search query. The rewriting itself is normal behavior, so it's not that your setting is wasted. There is value in having an apt description prepared in the first place.

Steps for creating a meta description

Taking the above into account, the actual creation steps are as follows.

Settle on a single search intent for the page (what the reader wants to know)
Include the target keyword while writing the page's conclusion or benefit in the first sentence
Add concrete numbers and features, condensing the key points into the first 60 characters
Trim the whole to around 120 characters and close with a phrase that prompts action
Check where it gets truncated in the search result preview or on an actual smartphone, and fine-tune

Summary

A meta description that raises CTR is built around the smartphone display: condense the key points into the first 60 characters and keep the whole to around 120 characters. By putting the target keyword naturally in the first half to take advantage of bold display, and showing the answer to the search intent and concrete numbers first, you make it more likely to be clicked.

Avoid the NG patterns of reusing descriptions, listing keywords, and contradicting the body, and prepare a description for each page that conveys the reader's benefit. This accumulation is what shows up as a difference in visits even at the same ranking position.
