Quality Content is the key to SEO's success. Content is not just the content of the text. Images must form an integral part of their content strategy. Sometimes single-time pictures are much more effective than your 1000 word posts on your blog. It also helps to improve the quality and performance of blog posts.
Images, Infographics, Videos, and all other multimedia content on the site help you increase your user engagement on your site and keep visitors on your site for a longer period of time to help reduce your bounce rate.
You can not add images to content, but optimize these images for better SEO performance. Image optimization should be an important aspect of a site optimized SEO process.
If you use the images in your content, there are many aspects that consider SEO aspects.
Relevancy
Using pictures does not mean that you upload the content of many images. You should only use this if you need it and use content that is more relevant to your content.
Placing pictures is another important aspect. Content must be placed in the right place according to the text content.
Using Original Images
Originality always helps to improve user experience and authority. Use the original images to help improve SEO performance. You can create original images with a graphic designer or take your own photos with a quality camera. That's why White Hat SEO companies use talented graphics to create quality images.
If you can not apply an in-house graphics application or if you run out of time, you can always use high quality images from the internet. But the important factor to consider is that you have to be free from copyright.
There are many tools available for free purchase of copyright at no cost. The most popular are Unsplash, Flicker, Freeimages.
Image Size
Images are the main source for attenuating your site's speed. And your site's speed is a decisive factor in SEO performance. So you have to be careful to use the pictures without jeopardizing the speed of the page.
In addition, it does not affect picture quality, it must provide a good balance. This can be achieved by compressing the file size by compression.
Filename
Crawlers are visually impaired, can interrupt up to 5,000 word-of-mouth content, but can not interrupt any single image on the image. This is why keyword-rich filenames are used for images, an important aspect in image optimization.
Google Bots and other crawlers can read the filename of the image and, if named with the target tag, it gives the search engines an indication of the subject of the image and thus helps SEO performance.
For example, if the image is about selling sports shoes, then "IMG_89868" instead of the file name is "Black_Tennis_Shoes".
Alt text
Like the filename, search engines read the Alt text of the image. Alt is an HTML attribute known as "Subtractive Text" to describe the content of the images.
You must use Alt text that is relevant to images and should be clear and descriptive. You can use the keywords in Alt, but be careful about filling in keywords.
If you do not focus on image optimization, there is a huge opportunity to improve SEO performance. You can use the abovementioned best practices in the page optimization process.
