It is true that a picture tells a million words and web masters like to use them to attract visitors to their web site. But in the aspect of search engine optimization, it is also an actual fact that search bots cannot view images. When a crawler comes across a JPEG or any picture format file on the website, it does not know how to decipher whether it is a picture of a car or a hot babe, so you will need to show them the way by some techniques which I am going to share below.
1. Use the ALT Attribute of the Image
Images or picture are embedded into a web page by inserting a line of HTML codes:
<IMG SRC=”image.jpg” WIDTH=”XXX” HEIGHT=”YYY” ALT=”description” TITLE=”title” >
If you are new to HTML code, I will decode it.
<IMG> - Indicate that there is an image to insert
<SRC> - Determine the location or file path of the image file
WIDTH and HEIGHT - Define the size of the image in pixels
The above four attributes are pretty standard but for the next 1, you must pay REAL attention to it.
The ALT attribute states what a web browser should display in the situation that the image file is not available or have error displaying on the page. Instead of getting the chosen image, the visitors would see the text that is being entered between the ALT attribute. This is also the way to help the search bots to read and determine the content of an image file. For example, if you have a cat picture, search bots cannot decipher whether it is a cat unless you enter the ALT description as “cat”.
2. Use the TITLE Attribute of the Image
The last attribute for the <IMG> tag is the TITLE attribute that assigns a title to the image you have. It will displays the text when a user hovers his mouse cursor over the image
While the TITLE attribute crawl rate is not as often as the ALT, it still stands for a chance for the crawler to understand your images as text.
