What is alt text?


The alt attribute is a picture description consisting of several words, read by the crawler when page is indexed. If user has disabled the graphics support function in the browser, then the contents of the tag will be displayed instead of the picture. The text for this attribute should not be too long.

The title attribute is a description for the visitor. If the user rest the mouse cursor on the picture for a couple of seconds, title attribute will appear. Usually, to fill this tag a detailed description of 1-2 proposals is used.


Why do we need alt tags?


No doubt, the graphic image will load correctly even if the image tags do not have img alt and title. But in this case, the possibilities of SEO images will remain unactivated. Having spent a bit of time creating an alternative description, webmaster will be able to:

  • transmit the necessary data to search robot;
  • attract new visitors;
  • increase readers’ loyalty.

Search engines examine uniqueness of graphic images, but they are not able to analyze their thematic identity. Therefore, if a webmaster wants a robot to categorize a picture, then it should make up a text for the alt tag.

In addition to main search, Google and Yandex have a “images” service. By creating optimized descriptions imag tags, webmaster increases the chances that Internet users will be able to come across his website using this service. In result, traffic growth will be ensured.


How to use tags in SEO promotion?


To attract leads to promoted requests, webmaster has to make up descriptions using key phrases for alt and title. The text created for alt tag can look like this: “adjective + key phrase”. For the title attribute, it is recommended to create complex sentence “adjective + key + addition”.

For instance, let’s take a key ” New York real estate “. For such key, you can draw a description alt “New York real estate luxury”, as well as the title “luxury real estate in Manhattan, New York.” An optimized description of image should contain such words as “photo”, “picture”.
