If you want more traffic on your website, you must optimise the images as they generate a ton of traffic from Google Images. Have you ever puzzled over what image file types should be used or if there is a need to add file names and alt text to every image on the website?

For effective SEO and for more traffic on your site following are some of the best practices:

1) Alt Text

2) File Size

3) File name

4) Captions

5) File Types

6) Sitemap

Alt Text

Alt text refers to a text alternative for images. Many a times it happens when we try to open an email on desktop or mobile and the images don’t get loaded. As a part of effective SEO, we want to take advantage of writing a descriptive, keyword rich alt text to increase the likelihood of click-through rates even if our images can’t render properly for our users. Additionally, if an image is decided to be taken as a link, it should be assured that alt text is included in it and that text is relevant to the link’s destination for a healthy user experience.

Image Size.

User is most important for a search engine like Google, so the chances of an image being most visible widens when an image reflects what users search for. For images the best approach is to have high quality and easy to engage images. Following are some of the guidelines:

i) use clear and crisp photos

ii) crop the images to the correct size of page width.

iii) show a smaller image and provide  option for a larger view.

iv) Reduce the color depth to lowest acceptable levels.

Image File Name.

having a detailed filename for an image is the key. the aim of giving an image a detailed or descriptive filename is to make Google or any search engine comprehend the image, so that it can help in a good user experience. But it should not be spammy by writing excessively long or keyword stuffed file names.


As per Google, it is a good idea to make sure that images are placed nearest to the relevant text and along with it providing good and descriptive captions to images add up to give an advantage.

Elements to be considered are:

i) the number of intervening words between the text and the image.

ii) the number of intervening table data tags between text and image.

iii) the number of intervening table rows tags between text and the image.

File Type.

It is advices to use commonly supported filetypes. it is commonly known that the most widely accepted and recommended type of image file type is JPEG and PNG as the second choice. So, it is a good to have the commonly supported file type matched with file name.

Image Sitemap.

Another important piece of advise for effective optimzation of image is to supply an image sitemap. Providing a sitemap is an effective way to help search engines to discover the images. Images should be consolidated into a single directory rather than spreading it out in numerous directories and sub-directories. This helps webmasters to stay organized and fetch data easily.

Closing Notes

In conclusion, optimising images on your website helps in SEO for maximising search engine benefits. We consider optimising the content and images for better rankings but the top most priority is User Experience. Great image content is an excellent way for site effectiveness. All the above steps should be considered for “icing on the cake” experience.
