Optimising images for search engines

Pictures assume a significant job in website design. They not just add a tasteful intrigue to your site however help in expressing ideas and thoughts.

They can influence buying habits, grab attention and make an enduring impression about your site on the customer. After all, an image is worth thousand words.

It's little marvel that Avatar with its delightful visuals, amazing symbolism and eye-popping illustrations has been so fruitful in the cinema world.But what would search engines like Google believe Avatar? Let’s begin by analysing how Google views an image:

Alt attribute:

Google and other search engines are visually impaired when it involves images. So they check out the alt attribute to read the outline of the image. If you've got an image of a person with a cheesy grin, put “man with cheesy grin” inside the alt attribute. Try to summarise what the image is about; don’t overdo it though. This will not only help search engines but is useful for visitors who disable images or use text readers.


The alt attribute is usually , but incorrectly, mentioned because the “alt tag”.

File names:

Use a descriptive file name. If the name of your file is “0001.jpg”, then search engines don’t know what it represents. It’s far better to possess “man-cheesy-grin.jpg” as a file name. As with alt attributes, don’t get carried away. Having an extended file name like “silly-looking-man-with-cheesy-toothy-grin.jpg” may be a bad idea. Also, it is good practice to separate words in a file name with a dash instead of an underscore.


you ought to use relevant images for your website. Search engines examine the copy/text round the image and see how closely the 2 relate to every other. If you're selling car polish, then having a picture of a gorilla will throw search engines off. Customers may get the joke but search engines don’t have a sense of humour.


Now that you simply realize alt attributes and descriptive file names, attempt to use keywords in them. If you're using “cheap car polish” as a keyword, plug that keyword into the file name and alt attribute of your car polish image.

Although search engines place more importance on actual text than images, it's good practice to optimise images. This way search engines will be able to understand what your image is about and your page rank will increase in organic search results.

But returning to Avatar, would Google enjoy it? Maybe if it had sub-titles.
