Why ALT text is important in web design?

User alternate text wherever we have pictures, icons, thumbnails which also helps in SEO and works as image placeholders. Alternatives text is used as a replacement for an image, whenever the image cannot be seen. This can happen, for example, when someone:

  • uses a screen reader (e.g. a visually impaired person)
  • uses a text-only browser (e.g. browsing from a mobile phone)
  • uses a graphical browser with images turned off
  • has not yet downloaded the image
  • browses results from a Web search
  • fails to download the image because of a network problem
  • copies an extract from a Web page into a word processor.

GUI guidelines for information presentation

  • Organize the user interface so that the information flows either vertically or horizontally, with the most important information always located in the upper-left corner of the screen.
  • Group related controls together using either white space or a frame.
  • Place the most commonly used command button first.
  • Assign meaningful captions to command buttons.
  • Place the caption on one line and use from one to three words only.
  • Command buttons in the interface should be sized relative to each other.
  • If the command buttons are centered on the bottom of the screen, then each button should be the same height; there widths, however, may vary.
  • If the command buttons are stacked in a corner, then each should be the same height and the same width.

Most Common Reasons for Advertising

The most effective means of advertising will often depend on company’s industry, business objectives and financial situation. Online companies may benefit more from Internet advertising since people can go directly to their websites. A television ad campaign will not be very feasible and effective if you do not have the necessary advertising budget. Similarly, reasons also vary for each advertiser for their business, product or services.
