You should enrich your content with pictures to make your website more attractive and improve the customer visitor experience. The image file name and alt text should also contain a relevant keyword, but still accurately reflect the content of the image. It is key to think about the file size of images you add to your site and to try and keep them as small as possible, without losing quality. The faster your site loads, the more professional it will appear and, ultimately, the higher it will rank.
All images should be stored in a compressed file format. The JPEG format (.jpg) is usually the best choice for full-color photos, where a little loss of quality is okay while retaining the ability to tell what it is, making file sizes very small and fast to load. PNGs are a lossless compression format, and while they take a little longer to load, they are good for text and drawings where losing quality would make it difficult to understand or read what is in them.
Look online for plentiful, low-cost stock image resources where you can quickly filter and find the right photo or illustration to complement your copy. These sites will list the requirements for purchasing rights or crediting the source so you can ensure you're staying on the right side of your
