An image speaks more than what 1000 words can do is an often repeated cliché. It is never a good idea to start an essay with a cliché but when it comes to SEO and web design, images are very important and crucial. In fact, websites that feature good images with great resolution, titles and named properly and sized properly often rank better in search engine queries than those websites that upload images haphazardly.
Images bring a lot of traffic to websites

Google Image and other image search engines routinely bring a lot of traffic to a website. Thus, web designers must note that images play a very important role in SEO and they cannot be ignored. Some of the important reasons why images are important to SEO can be listed below:
1. Images are searched for uniquely by visitors on search engines.
2. Images are attractive and capture the imagination of the visitors.
3. Images are different from text and require less hard work when it comes to creation.
4. They fill an empty webpage in a visually attractive manner.
5. Images can be altered and modified even after they go live.
With these factors in mind, one must understand that images are a great way to solve many issues that plague a website. Whether it is about a lack of great content or about not being visually appealing, images can fix a lot of issues that companies commonly face.

Websites with good images are ranked higher by search engines

Websites that have images of good resolution and quality are ranked higher on websites than websites that do not have images. While designing a website, web designers must ensure that images do not take a lot of time to load. If they take a lot of time to load, it may cause problems with the webpage being indexed by search engines. Those websites that take a lot of time to load and those that return a lot of error messages are often pushed to the bottom of the list by search engines.

Here are some tips for web designers to make websites SEO-friendly
1. With this in mind, web designers should ensure that all graphical content on a website load fast and that they do not increase the time of a loading a webpage.
2. Web designers should also ensure that images that are uploaded via FTP servers are not too heavy and that they match the web standards.
3. The format of the image file must be preferably .JPEG, .GIF or .PNG. Other image files do not load particularly fast and may create problems with SEO.
4. Designing a website is not only about making information and media appear attractive, but it is also about ensuring that a website appears in search results quickly and accurately.
Professionals at a web designing company should make sure that their clients are made aware of the implications of heavy images. Both heavy images and lack of images can harm a website with respect to search engine optimization. A company should maintain a fine balance between not using images at all and using graphic-heavy image files.
