SEO Dictionary: Terms Starting with “H”

1. Heading Tags
Heading tags (H1, H2, H3, etc.) are HTML elements used to define headings and subheadings on a web page. They help organize content for readability and structure, and search engines use them to understand the hierarchy and relevance of content. The H1 tag typically denotes the main heading of a page, while H2 and H3 tags represent subheadings.

2. Header Tags
Header tags are HTML elements (H1, H2, H3, etc.) used to create headings on a web page. They help with content organization, improve readability, and provide a hierarchy of information. Proper use of header tags enhances SEO by making it easier for search engines to understand and index content.

3. Hyperlink
A hyperlink, or link, is a clickable element that directs users from one webpage to another or to a different section within the same page. Hyperlinks are essential for navigation and are a key component of SEO. They can be internal (linking to pages within the same website) or external (linking to pages on different websites).

4. HTTP (Hypertext Transfer Protocol)
HTTP is the protocol used for transmitting data over the web. It defines how messages are formatted and transmitted, and how web servers and browsers should respond to various commands. HTTPS (Hypertext Transfer Protocol Secure) is the secure version of HTTP, which encrypts data for secure communication and is a ranking factor in SEO.

5. HTTPS (Hypertext Transfer Protocol Secure)
HTTPS is a secure version of HTTP that encrypts data transmitted between a web server and a browser. It uses SSL/TLS certificates to ensure that data is secure from interception and tampering. HTTPS is an important ranking factor for SEO and provides a trust signal to users, indicating that their data is protected.

6. HTML (Hypertext Markup Language)
HTML is the standard markup language used to create and design web pages. It structures the content on the web, including text, images, links, and multimedia elements. Proper use of HTML tags, such as title tags, meta descriptions, and heading tags, is crucial for SEO.

7. Hidden Text
Hidden text refers to text on a web page that is not visible to users but can be seen by search engines. This practice, such as using text in the same color as the background, is considered a black hat SEO technique and can lead to penalties from search engines. Hidden text is often used to manipulate search engine rankings deceitfully.

8. Homepage
The homepage is the main or starting page of a website, typically accessible via the domain's root URL (e.g., www.example.com). It often serves as the central hub for navigation and links to other pages on the site. A well-optimized homepage can set the tone for the site’s SEO strategy and user experience.

9. Hash Tag
A hashtag is a keyword or phrase preceded by the "#" symbol used in social media posts to categorize content and make it discoverable. While hashtags are not directly related to SEO, they can increase the visibility of social media posts, drive engagement, and indirectly influence website traffic through social channels.

10. Header Bidding
Header bidding is an advanced programmatic advertising technique that allows publishers to offer ad inventory to multiple ad exchanges before making calls to their ad server. This process aims to maximize ad revenue by enabling competitive bidding and can impact site performance, which indirectly affects SEO through user experience factors like page load speed.
