As we know SEO is the best way to achieve the top ranking in different search engines. The most important part in achieving better ranking is on page optimization. Good quality content is the important factor to get your website to the top. There are also other factors considered i.e. Image Optimization.
Image Relevancy and Alt Tag
Image relevancy is very important for SEO image optimization. Image ALT tag plays an important role in optimization factor. ALT means Alternate. If we apply at the tag on the image, then text is displayed instead of an image. The ALT tag is helpful for text based search engines i.e. they cannot read videos or images. In that case an empty space appears instead of images. Empty space is not good for SEO. ALT tag tells the search engine that there is an image in that placed or also tells the topic of the image. A good use of ALT tag is to keep short but descriptive. Always fill the ALT tag with search friendly information. For example, the ALT tag for the SEO company picture should be like alt=” Best SEO Company” or “SEO Services Company”.
Image Size
The size of the image is very important for user point of view. Images can make your website heavy. It is recommended image load time should be less so that the user cannot hit the back button. Images should be clear and does not heavy. To make images lighter, “Yahoo Smushit” is the best tool to remove the unnecessary image's bytes.
Image Hosting
Hosting of the image drives the traffic to your website through image search. It is believed that images hosted on the same domain have more value rather than hosted in the different domains.
Image Title and Linking
Proper image linking provide the better Google results. Never use the direct link to your images. Use anchor text for proper image linking. Also use the title tag whenever linking your images. Title tag shows the name of the image when you move cursor over the images.
