Header Tags
Header tags H1 through H6 in the order of importance are used as headings of pieces of content and the information contained within it is a small part of Google’s algorithm which determines website rankings.
Hidden Text
An old-school way of trying to cheat the search engines that no longer work. Black Hat SEO people used to hide text on the website by making the text the same color as the background, hiding it inside a dive that uses the CSS code display: none; etc.
Homepage
Also known as the Frontpage of the website located at the TLD (top-level domain). The page is usually named index.html, index.htm, index.asp, etc.
Hreflang Tag
This is a tag to let the search engines know what language your website content is. Here is an example of it in use.
<link rel="alternate" href="https://rocksolidseo.com" hreflang="en-us" />.htaccess File
This is a server configuration file where code is added to help redirect URLs to the proper place. For example, if you find a backlink that pointed to a page that does not exist anymore like yourwebsite.com/oldpage you can redirect people from that page to the new page yourwebsite.com/newpage to fix that broken backlink to your website. It is best practice to contact that website and correct it on their end because too many 301 redirects can become a bad thing.
HTML
HTML stands for Hyper Text Markup Language which is the code used to build websites. Certain elements of the HTML code are used to help with on-page search engine optimization such as header tags, alt tags, and meta tags. Note: The meta keyword tag is no longer effective.
HTTP
The HTTP in front of the website address stands for Hyper Text Transfer Protocol. This is used to transfer website data from the computer server to the web browser.
HTTPS
HTTPS (Hyper Text Transfer Protocol Secure) is the secure version of HTTP. It is recommended to pay for an SSL Certificate to get the HTTPS protocol if your website displays or asked for sensitive information such as social security numbers, credit card numbers, etc. If you are on a website where you are about to enter sensitive information like this take a look at the web browser and make sure it says HTTPS instead of HTTP. In some browsers, a padlock appears in the URL window as well. Note: If some of the images of the page are linked to HTTP instead of HTTPS the browser will say that the website is insecure.
Hub Page
The main category page or post of a topic is the parent page of sub-topics and sub-categories. Having the hub pages and sub-pages organized the correct way helps with siloing content for search engine optimization (SEO) purposes.
