Hit
Hit is a somewhat misleading measure of traffic to a web site. One hit is recorded for each file request in a web server’s access log. If a user visits a page with four images, one hit will be recorded for each graphic image file plus another for the page’s HTML file. A better measure of traffic volume is the number of pages/HTML files accessed.

HTML
The acronym HTML stands for HyperText Markup Language, the authoring language used to create pages on the World Wide Web. HTML is a set of codes or HTML tags that provide a web browser with directions on how to structure a web page’s information and features.

Hyperlink
Also known as link or HTML link, a hyperlink is an image or portion of text that when clicked on by a user opens another web page or jumps the browser to a different portion of the current page. Inbound Links with keyword-relevant Link Text are an important part of Search Engine Optimization Strategy.

Index
An index is a Search Engine’s database. It contains all of the information that a Crawler has identified, particularly copies of World Wide Web pages. When a user performs a Query, the search engine uses its indexed pages and Algorithm set to provide a ranked list of the most relevant pages. In the case of a Directory, the index consists of titles and summaries of registered sites that have been categorized by the directory’s editors.

Inbound Links
Also known as back link, backward link, or backlinks, inbound links are all of the links on other websites that direct the users who click on them to your site. Inbound links can significantly improve your site’s search rankings, particularly if they contain Anchor Text keywords relevant to your site and are located on sites with high Page Rank.

Google AdSense
Google AdSense is an ad-serving program operated by Google that provides relevant text, image, and video-based advertisements to enrolled site owners. Advertisers register via Google AdWords and pay for ads on a Pay-Per-Click, Cost-Per-Thousand or Cost-Per-Action basis. This revenue is shared with Google AdSense host sites, typically on a PPC basis (which sometimes leads to Click Fraud). Google uses its search Algorithms and Contextual Link Inventory to display the most appropriate ads based on site content, Query relevancy, ad “quality scores,” and other factors.

Google AdWords
Google AdWords is the Keyword Submission program that determines the advertising rates and keywords used in the Google AdSense program. Advertisers bid on the keywords that are relevant to their businesses. Ranked ads then appear as sponsored links on Google Search Engine Results Pages (SERPS) and Google AdSense host sites.

Graphical Search Inventory (GSI)
Graphical Search Inventory is the visual equivalent of Contextual Link Inventory. GSI is non-text-based advertising such as Banner Ads, pop-up ads, browser toolbars, animation, sound, video and other media that is synchronized to relevant Keyword queries.

Gray Hat SEO
Gray hat SEO refers to Search Engine Optimization strategies that fall in between Black Hat SEO and White Hat SEO. Gray hat SEO techniques can be legitimate in some cases and illegitimate in others. Such techniques include Doorway Pages, Gateway Pages, Cloaking and duplicate content.

Hidden Text

Hidden text is a generally obsolete form of Black Hat SEO in which pages are filled with a large amount of text that is the same color as the background, rendering keywords invisible to the human eye but detectable to a search engine Crawler. Multiple Title Tags or HTML comments are alternative hidden text techniques. Hidden text is easily detectable by search engines and will result in Blacklisting or reduced Rank.
