What is a meta description?

The meta description is a tag that describes the content of a webpage (usually 120-160 characters), which search engines choose to display below the title. It's not a direct ranking factor, but it strongly impacts the click-through rate (CTR). When the description clearly highlights the benefits and contains keywords relevant to the query, users are more likely to click, and a good CTR helps your page gain higher ranking over time.

What is a meta description? Why is it important?


Three fundamental principles before writing.

Stick to search intent, clear benefits, and concise length. Users are looking for quick answers to their problems, so you need to show them "Why should they click on this page now?". The ideal length should be around 140-155 characters to include enough information without being truncated in search results. Avoid vague descriptions or keyword stuffing.

7-Step Meta Description Optimization Process

Step 1: Identify your search goals and main keywords.

Choose one main keyword that accurately reflects the user's search intent. For knowledge blogs, this is often a keyword like "what is," "how to," or "guide." For sales pages/landing pages, prioritize transactional keywords ("price," "buy," "service"). Without keyword research tools, you can type the keyword into Google to see suggestions, "people also ask," and the titles of top-ranking pages to deduce the language users are actually using.

Step 2: Identify the reader and the benefit of each sentence.

Write a sentence describing who will read it and the specific benefit they will receive when clicking on the page. For example: "New shop owner doing SEO" + "5-minute checklist to do immediately". This benefit sentence is the "soul" of the meta description, helping you avoid getting bogged down in a dry list of features.

Step 3: Choose a suitable writing "formula".

You can use the following sentence structures (fill in the blanks), then adjust the text to make it smoother:

  • Problem → Solution → Result + CTA: “Having trouble increasing CTR? Learn how to write SEO-optimized meta descriptions that align with search intent to attract clicks. See the detailed guide now.”
  • Target Audience → Benefits → Differentiation: “For small businesses: Optimize meta descriptions step-by-step, with real-world examples and quick fill-in templates. Apply in 10 minutes.”
  • Features → Benefits → CTA: “SEO-friendly meta description: Standard length, natural keywords, compelling CTA. Download the template and start optimizing today.”

Step 4: Write a draft of 140-155 characters, including the main keyword early.

Create 2-3 different versions, with the main keyword appearing naturally in the first half of each sentence. Each version should highlight one key benefit; avoid cramming too many ideas into one version.

Example (for this exercise):

"What is a meta description? A step-by-step guide to writing SEO-optimized descriptions that align with search intent, significantly increasing your blog/landing page's CTR. Check it out now."

Step 5: Add a soft CTA to motivate clicks.

Conclude the description with an invitation that shows the reader "what they'll get if they click": "View now," "Download template," "Apply in 5 minutes," "Learn step-by-step." The call to action (CTA) should be concise, not overly sales-oriented, and relevant to the content context.

Step 6: Add the description to the page and check the display.

In HTML, insert:

<meta name="description" content="What is a meta description? A step-by-step guide to writing SEO-optimized descriptions that match search intent and significantly increase CTR. Check it out now.">

If you're using a CMS (WordPress, Shopify, etc.), go to the SEO/Meta description section of each page.

Step 7: Monitor CTR and optimize periodically.

After publishing, open Google Search Console → Performance → Pages, select the optimized page to view Impressions/CTR/Clicks. If after 2-4 weeks the CTR is still low compared to the search average, go back to Step 4 to try a different description: Emphasize benefits more, shorten the wording, or adjust the CTA. Repeat the write-attach-measure cycle until the CTR improves.

Quick practice: Write meta descriptions for 4 types of pages

Knowledge blog page

Suggested formula: Clear topic + learning benefits + CTA.

Example: “What is a meta description? A 7-step process for writing a standard SEO meta description, with a quick template and real-world examples. Apply now to increase your CTR.”

Product/Service Page

Suggested formula: Problem → Benefit → Trust factor + CTA.

Example: “Complete SEO service package helps increase organic traffic, optimize technical aspects & content safely. Transparent pricing, clear contract. Get a consultation.”

Category page

Suggested formula: Product range + selected benefits + assurance signals.

Example: “SEO-friendly landing page template, optimized for conversions for SMEs: clear layout, fast loading, easy to edit. Discover the latest template collection.”

GTG CRM landing page

Suggested formula: Key feature + quick operation benefit + Call to Action (CTA).

Example: “Create landing pages and write SEO-optimized meta descriptions directly within GTG CRM. Preview snippets, publish quickly, and easily track performance.”

Checklist for 60 seconds before clicking "Publish"

  • Around 140-155 characters in length, readable smoothly.
  • Include one main keyword naturally, preferably appearing early.
  • State the benefits clearly, avoid vague slogans ("top quality," "good price").
  • There are soft CTAs (view now, download templates, apply quickly…)
  • Each page has a different description, with no repetition between pages.
  • The content on the page matches the actual content.

Common mistakes and how to fix them quickly

Your ads may not be optimized if you make the following mistakes:

1. Many descriptions are cut short because they are too long; shorten the last clause or remove cumbersome modifiers.

2. Others stuff keywords into their sentences, making them stiff and unconvincing. Instead, stick to one main keyword and shift the rest to specific benefits.

3. The most serious error is duplicate descriptions across multiple pages, making it difficult for Google to differentiate them. Prioritize descriptions that reflect the specific intent of each URL.

4. Finally, don't promise things the page doesn't have – Google may automatically generate a different description if it finds yours doesn't match the content.
