Perfect, all images have ALT attribute.
Number of images: 3
Missing alt tag: 0
The "alt" attribute provides a text equivalent for the image. If the browser cannot display an image the alt description will be given in its place. Furthermore, some visitors cannot see images as they might be blind in which the alt tag provides a valuable image description. Finally, search engines utilize the alt attribute for image search indexing. (


We have found following title:

"Photonic Science intensified ccd cameras and scientific detector systems visible to x-ray and neutron detection"

Length: 111 characters

Warning: The title is 111 characters long. The title should not exceed 80 characters.

The <TITLE> element provides a short piece of text describing the document. The title is very important as it shows in the window title bars, bookmarks and search results. Title should be between 60 to 80 characters long. (

Description Metatag

We have found following description:

"Photonic Science specialize in intensified ccd cameras and systems for the scientific market. Photonic Science is a high technology independent manufacturer of scientific detector systems covering the range of visible to x-ray and neutron detection. Cooled CCD cameras.
