An image is a design having a similar mark as some subject, usually an object or a person. Images can be two-dimensional (for example, photos, screenshots, maps, charts), or three-dimensional (statues or holograms). Embedding images in your articles is one way to optimize your web pages for visitors because images add meaning and elegance to your web page design and formatting. Including alt tags in image descriptions is another way of on-page optimization because some browsers do not support image views, and alt tags display instead of the missing images.


In SEO terminology, impressions are related to online advertising and web traffic. In this sense, an impression is called cost per thousand impressions (CPI) or cost per mille (CPM). An online advertisement impression is a single appearance of an advertisement on a web page. Each time an ad loads onto a visitor’s screen, the ad server may count that loading as one impression. AdSense publishers on sites earning revenue for advertising impressions will find information about impressions in their Google Analytics (or Google AdSense account) under the term RPM – revenue per thousand impressions. RPM is not a portion of finalized total earnings, but rather an estimation of how much you would earn if an ad was to be loaded on a specific page after 1000 unique visits.

Indexing is a method by which web pages are classified in search engine databases. Each search engine uses a different algorithm to accredit web pages with a PageRank or places of appearance in the search engine index. In other words, Web indexing is a process designed for search engines to find web pages on the Internet.

Inline text links

Inline text links are one of the most effective methods of internal linking (besides text links and links within website footers). Inline text links are contained within the body of some element of the web page content, such as article or blog. They differ from text links which contain anchor tags and keywords. These types of links (inline links) display remote content which may be accessed even without link selection. They can be in form of images, thumbnails, cropped or magnified sections, or low resolution previews.


In computing, user interface is a tool referring to a point of interaction between components, or more precisely, the space where interaction between humans and machines occurs in the field of human-machine interaction. More precisely, the user interface in a computer program is a tool referring to the graphical, textual and auditory information the program presents to the user, and the control sequences, for example, key strokes, computer mouse movements or touchscreen selections.

User interfaces exist in various systems and include both physical and logical (hardware and software elements). However, user interface, operator interface and human–machine interface, are not all the same terms.

Internal linking

Internal linking is an SEO strategy consisting in linking up your articles, blogs or web pages together in order to get your web pages properly crawled and found by search engines (indexed), build the relevance of the pages to targeted keywords and increase the PageRank.

Internal links

Internal links are links leading to different web pages within the same domain (website). The exception are links on a blogging platform (domain) because blog links are viewed as internal only if they are the links within the same blog, and not the links leading to other blogs inside the same blogging site or domain.


The Internet is a network made of different systems and private, public, business, academic and similar networks, linked together by different electronic, wireless, and optical technologies. This global system supports e-mail services and contains numerous information resources and services, normally accessible through hypertext documents (texts containing hyperlinks leading to other documents) which make the World Wide Web.

Internet Explorer

Internet Explorer is a series of graphical web browsers developed by Microsoft for retrieving, presenting, and traversing information resources on the web.

IP address

An IP address (Internet Protocol address) a numerical consign ascribed to devices participating in a computer network using the Internet Protocol for communication, such as computers or printers. Two main functions of IP addresses are identification of the host or network interface and location of the address. It’s recommendable to online article writers and bloggers who track their web pages performance in Google Analytics, to exclude their IP address for more accurate reports.

Italic text

Italic text is a cursive interpretation of characters (the kind of typeface often slanted slightly to the right). This typeface is based on a stylized form of calligraphic handwriting originated in Italy started for chancery (historical handwriting style) purposes.
