Emojis have long since moved beyond messaging apps. Today, they are used in website headings, email newsletters, meta tags, and even code. But every emoji has a specific encoding, and mishandling it can break how it is displayed and affect rankings.
What are emojis
Emojis are standardized pictograms defined by the Unicode standard. Each character has a unique code point: for example, 😀 is U+1F600, while ❤️ is U+2764 + U+FE0F (a base character plus a variation selector).
The Unicode Consortium regularly releases new versions of the standard with additional emojis. As of 2026, the standard includes more than 3700 emojis in Unicode version 15.
Encoding and display
Unicode and UTF-8
To display emojis correctly on a website:
- Save HTML files using UTF-8 encoding
- Specify
<meta charset="UTF-8">in<head> - Configure the database and columns to use utf8mb4 (MySQL/MariaDB) or UTF8 (PostgreSQL) — MySQL's standard utf8 does not support 4-byte characters
There are three ways to insert emojis in HTML:
| Method | Example | When to use |
|---|---|---|
| Directly | 😀 | Preferred when using UTF-8 |
| HTML entity | 😀 | For compatibility |
| CSS content | content: "\1F600" | In pseudo-elements |
Differences between platforms
The same code point can look different. The 😀 emoji looks different on iOS, Android, Windows, and macOS because each platform comes with its own emoji font (Apple Color Emoji, Noto Color Emoji, Segoe UI Emoji).
Keep this in mind when using emojis in a UI: something that looks good on a Mac may look different on Windows.
Emojis and SEO
Impact on CTR in search results: Emojis in the <title> tag and meta description appear in Google and Yandex snippets. According to several A/B tests, irrelevant emojis do not increase CTR, while relevant ones (for example, ⭐ in reviews) may increase it by up to 5-10%.
Search engine limitations: Google may not display emojis in a snippet if it considers them irrelevant or “clickbait.” Yandex is more accepting of emojis in titles.
Structured data: If you use Schema.org markup (for example, Review, Product), do not insert emojis into the schema's string fields — this may invalidate the markup and reduce the chances of getting Rich Snippets.
Indexing: Search engine crawlers treat emojis as ordinary Unicode characters and index them. They carry no special SEO weight, but may be used when generating a snippet.
Emoji accessibility
Screen readers (assistive technology that reads content aloud) pronounce emojis using their official Unicode names: 😀 is read as “grinning face.” This does not always fit the page context.
To control how screen readers handle emojis, use ARIA attributes:
<!-- Декоративное эмодзи — скрыть от скринридера -->
<span aria-hidden="true">🎉</span>
<!-- Смысловое эмодзи — описать явно -->
<span role="img" aria-label="Успешно выполнено">✅</span>Do not use emojis as the only way to convey meaning — always provide the information in text as well.
Practical tips
Don't overdo it: 1-2 emojis in a heading serve as emphasis; 5+ look like spam. Search engines may consider excessive emojis in tags to be a sign of low-quality content.
Test on different devices: Open the page on iOS, Android, and Windows before publishing — the same character can look very different across platforms.
Avoid emojis in URLs: Some systems do not handle Unicode percent-encoding in URLs well (%F0%9F%98%80), which can break analytics and links.
Use code points in CSS: When using emojis in content: CSS, specify the Unicode code point rather than the character itself — this improves compatibility.
Tool on reChecker
The “Emoji” tool on reChecker helps you find the right character by name or category, copy its code, and check how it displays — useful when working with meta tags and content.
