Important SEO Attributes Explained
Attributes add specific instructions or context to HTML tags. In SEO, they guide how search engines interpret and interact with your web content.
1. rel=
The rel (short for “relationship”) attribute defines the relationship between the current page and the linked resource. Used mainly for SEO, security, and link behavior control.
Common rel values used in SEO:
rel value | Meaning / Use |
nofollow | Tells search engines not to pass link authority (use for sponsored or untrusted links). Example: <a rel="nofollow" href="https://external-site.com"> |
noopener | Improves site security and performance by preventing the new tab from accessing the original page via JavaScript. Example: <a href="https://example.com" target="_blank" rel="noopener noreferrer">Visit Site</a> |
noreferrer | Hides the referring URL from the target page to protects user privacy Example: <a href="https://example.com" target="_blank" rel="noopener noreferrer">Visit Site</a> |
sponsored | Marks paid or affiliate links. Example: <a rel="sponsored" href="#"> |
ugc | Indicates user-generated content (blog comments, forums). Example: <a rel="ugc" href="#"> |
canonical | Tells search engines the preferred version of a page if multiple versions exist. Example: <link rel="canonical" href="https://example.com/page" /> |
alternate | Signals that the linked page is an alternative version (like different language/region) of the current page. Example: <link rel="alternate" hreflang="en-my" href="https://example.com/my/" /> |
2. href=
The href (short for “hypertext reference”) attribute points to the web page you want the link to open.
Used inside the <a> (anchor) tag to tell browsers where the link should go.
Example: <a href="https://www.rankpage.com.my/">Visit Rankpage</a>3. src=
Defines the file path for images, scripts, or videos.
Example: <img src="logo.png" alt="Company Logo">4. alt=
Used inside image tags to describe the image, important for accessibility and SEO.
Example: <img src="banner.jpg" alt="2025 SEO Specialist">5. name= and content=
Used in <meta> tags to define things like description, viewport, charset, and so on.
Example: <meta name="viewport" content="width=device-width, initial-scale=1.0">Fact: Attributes inside HTML tags are unordered, they all sit inside the <a …> tag and are read equally by the browser.
Understanding SEO Symbols and URL Parameters
Symbols used in URLs and HTML code are often misunderstood. Here’s what they mean:
Symbol | Meaning | Common Use |
/ | Separates directories | example.com/shoes/sneakers |
? | Begins URL parameters | example.com?page=2 |
& | Separates multiple parameters | ?utm_source=google&utm_medium=cpc |
= | Assigns a value to a parameter | color=blue |
# | Anchor to a specific section | example.com/about#team |
These symbols help define tracking links, filter URLs, and support dynamic content without creating duplicate content.
Heading Tags and Content Hierarchy
Search engines use heading tags to understand the structure, priority, and context of content on your page. Just like an outline in a report, heading tags help both bots and humans navigate content logically.
- <h1>: Main title of the page, use only once per page.
- <h2>: main sections of your content
- <h3>–<h6>: These are used for more detailed subtopics or groupings, FAQs, or smaller groupings.
Example:
<h1>Ultimate SEO Guide for 2025</h1>
<h2>What Is SEO?</h2>
<h3>On-Page SEO Basics</h3>
<h3>Technical SEO Essentials</h3>
Tip: Avoid skipping levels (don’t jump from <h1> to <h4>) as it may confuse both users and bots.
Symbols in HTML Content (That Aren’t Just Decoration)
These are called HTML entities and are used to display characters that would otherwise be read as code.
Symbol | Code | Purpose |
| Non-breaking space | Prevents line breaks in text |
& | & | Used in HTML to show ampersand |
< and > | < and > | Shows angle brackets on page |
" | “ | Displays quotation marks in HTML |
How Developers and Marketers Should Collaborate
- Marketers need to understand the purpose of each HTML tag and where it should be placed for SEO impact.
- Developers should ensure tags are implemented consistently and correctly in the site’s codebase or CMS templates.
- Use shared documentation to align on tag usage, naming conventions, and SEO best practices.
- Audit implementation together using browser Inspect tools or SEO plugins (like MozBar, Ahrefs Toolbar) to verify live pages.
