Normally webpage accomplishes with text, videos, and images. A best practice is a 1500 to 2500 words article that has at least three images. If you have advertisements on your webpage then you should wisely manage images and advertisements. When choosing images, it is better to create new images rather than download them from free image-giving websites. You should hire a graphic designer for your website. Images should have clear photos with the short text and URL of your website. ALT text is give accessibility to search engines to understand what is an image and its description.
Image Metadata Such As Image Title, Image description, and country of origin are important in many image-based search engines. As an example, you create a website about pets. The image may contain photos of dogs, cats, birds, etc. sometime your dog. That is a rare fresh image, so you need to protect it. Image metadata helps to avoid stealing it into other's websites. Then you should say a few words about that section on the webpage near your image. Paragraphs belonging to dogs can say a short title about that section. You can consider H2 or H3 tags. You can write the same details as what have in H2 in the image too as ALT attribute. Visitors first look at the image then the heading and finally the paragraph. Somewhere in the image, you should tell about the URL of your website. This is the basic preparation of the image.
The most important part of the images is ALT-Text in HTML. Many search engines grab ALT attributes in images. However, images should have unique images rather than be downloaded from somewhere. What is the best practice for ALT-Text? This is a common question.
ALT-Text should add personality to the image as well as the relevant section on the webpage. My advice is to use fewer than four words. Don't use "image of" or "photo of" such common words. It is a waste length of ALT-Text. It is the best practice that uses direct details about the image. Use adjectives or adverbs that can be giving similar meanings to the main keywords. A clear direct sentence with four words gives a meaningful understanding to search engines. What you should avoid is not spamming keywords or don't try to mislead visitors.
You should not think that search engines consider ALT-Text for ranking. But they may be used as a ranking factor. A lot of times, I use two words in ALT-Text. Not only ALT-Text, but you can also use the TITLE parameter in the image tag. Also, it may have a tooltip for enlarging an image or directly into another webpage. So tool-tip and title parameters are an extra chance to describe your webpage. This implies search engines that you didn't hope to keyword stuffing.
One reason for putting images between paragraphs is to give relaxation to visitors. They may be tired of reading long-length articles, so they use images to take a little break. On this side, images have a psychological factor. A better image gives a long-time break and visitors may look at images and texts in images. This helps to reduce the bounce rate.
So putting wise images gives a lot of benefits in SEO. The first image at the top of the page should give an impression of the title of the web page. It is a key factor that visitors stay on the webpage. The first image has a psychological reason, so choose it well thinking. Do not hurry up. If you can find a painter, you can give an idea about your webpage, then say to him draw a picture for the top image. Hand-drawing images give a huge user experience. Like that website has stunning traffic. Visitors may look at the image for a long time. As a bonus factor, your bouncing rate will be reduced. Even this image can impose your visitors to bookmark that webpage. He may visit that webpage for a few more days. So you can guess that image is not a simple factor in your website.
