After reading the title the first question that pops up is:
Why should you really optimize images? They are just a part of article.
Most of the bloggers don’t realize the importance of image optimization for their SEO, this will not only boost their chances for the first page results, but will also help Search Bots to properly index their sites in the correct niche.
Talking about benefits of SEO rich image, let’s count them all:
- Search bots are able to collect more accurate keywords for your site
- Your search results are boosted up
- You have a double chance to show up in the image search results page
- You can give more keywords than the usual keyword density
- Less Site load time (Search Engines like Google love it)
1. Properly naming an image
Naming an image is important, don’t just name is with numbers or irrelevant words from your topic or article always try to save it with a keyword rich name, so that “Image Search Engine’s” can find your image and obviously turn their users into your visitors.
2. Always give ALT tags to your images
If you are using WordPress for your CMS, then it’s pretty simple to give ALT tags to your images, just type in the related keywords in the ALT text box, while uploading any image into the media gallery and you are done. For example: –>
3. How to optimize images for load time.
Load time is decreased when you use less heavy images, a simple rule to follow is to keep your images less than 30KB in size. Most of the times we are able to achieve it through default paint application by the our Operating system, but sometimes you will have to use tools like Yahoo Smush.it to get it more compressed. See (below) I have managed to keep my image size under 30KB
Anyway keeping a good optimization scale for your images will always help you keep your site’s load time in control.
This also makes you an extra edge when your site is loaded on mobile devices having low internet speed.
4. Stick to Basic Image Extensions
Internet is a vast place to find everything and there are users still using old and basic web browsers, and many of them haven’t even upgraded their operating system from a decade. So keep things good from your side, you can always use the basic extensions (jpeg, PNG or GIF) for an image.
From my point of view I have used PNG and JPEG’s for my blog but a positive difference was felt when I used Jpeg extensions.
- The images were light, so it helped my blog to load faster
- It was more colour rich that other extensions
- It’s completely visible on a decade old browser.
- It can be shrunk more than other extensions, who try to protect layers of colours by adding more size to images.
