Understanding Image Optimization:


Images may seem like a straightforward component of our site, but we can optimize our website using them. Image optimization is one of the building blocks of on-page SEO optimization. Images are a strong visual component of a webpage. When it's come to Tutorials, pictures are worth a thousand words. We can use a chart or data flow diagram, or steps to do something using pictures easily rather than to spice up 1000 dull words.

In URL optimization, the keywords are important factor just like the image filename. Creative Descriptive but short keyword-rich file names can help search engines to determine relevancy. Image file names help Google and other search engines crawlers to know what the image is about.

Avoid using default image names as it does not give any information about the image. Use target keywords in Image name and use "-" (hyphen) to separate keywords as shown in above picture.

The Next most important image optimization factor is Alt Attribute. Alt stands for alternate. The "alt" attribute allows us to specify alternative name for the image. This alternative name is displayed in a place of the image if the image cannot be shown or is taking too long to load.

Most of the Search engines are text based, so they can't read images and videos. For them, the location of images or videos appears as empty space which is totally not good in term of SEO. In this time, the "Alt" Attribute comes up and tells the search engines that there is an image placed here and also tell them what the image is about.

Another reason to use alt attribute is that, if we're using an image as link, The alt attribute will be treated similarly to the anchor text of a text link.

Image formats:


Search engines prefer high resolution images and high-quality content. There are few things we can do when choosing image file formats.

Use .jpg or JPEG for larger photos or illustrations. it will give us a good result in terms of clarity with a relatively small file size. JPEG images maintains the quality when we compressed or resized the images.
Use .PNG if we want to preserve background transparency. We use PNG type format for our logos as the image appears small, yet the resolution is high quality. PNG files are larger in size which could disrupt the page's performance. Try to use JPEG file type where possible.
Use SVG for logos and other icons.

Image file size:


Image size is a very crucial factor as it directly affects the loading time of the page There are few things we can do to ensure our images doesn't slow down the page.

Compress images much as possible before uploading. There are many tools which can help us to compress the images size more than 50%. But make sure the image doesn't lose any pixels and become distorted as we compress the size of the file.
Resize the image to how we want to displayed it. The overall size of our images should not be much larger than we actually need it to be. If the image is 3200 x 1300 pixels and we set our frame to displayed image at 250 x 150 pixels size, still the entire image has to be loaded which can have a huge impact on loading times.
