The first very important point is to choose the best image available, which should be clear, attractive and beautiful for users. A good image should create a beautiful photo viewing experience for the user. In the following, some useful tips for choosing a suitable photo will be mentioned:

1- Optimizing site images for the site according to the image dimensions

The dimensions of an image should be at least 320 pixels and at most 1280 pixels. Smaller photos usually get lower ranks and larger photos are only displayed in the search results if the user manually selects the Large Image option.

In general, many designers choose the easiest way and use a full-sized image as a thumbnail. By changing the codes, designers change the length and width of the image when it is loaded and make it appear small. The point is that full-size images must first be cached in the browser, the designers forgot that at the moment of resizing, the original image must first be loaded into the cache. The page with thumbnails when loaded is actually a page with full size images loaded.

2- Image format ratio and site image optimization

To achieve the best ratings, always try to choose the normal format (i.e. square or SQUARE with aspect ratio 4:3 to 16:10) for your images. Photos that have a huge difference in the ratio of their length and width, usually get lower ranks. The logical reason for this is to preserve the appearance of the image search page of the search engine. Since Google displays all the images together on its search result page, if there are photos with unusual dimensions among them, the order of the page will be messed up.
