Proper Image Optimization – Semalt Expert
When it comes to talking about search engine optimization, you might consider that page index or articles optimized with keywords are the most important. However, images are an overlooked factor that will contribute to your website's ranking. There are different parts of image optimization that you must consider to show up your content on the first page of Google. Some of them have been discussed below, by Max Bell, the Semalt Customer Success Manager.
Fill out the alt text tags:
Alt text is often used for describing your images. Visually impaired users might not be able to see the pictures and content, but they can read the alt text, so you should include the alt text tags to your images. It lets the users understand the nature of your articles. Moreover, the search engines will not be able to scan all the pictures; so by including the alt text tags, you can tell Google, Bing, and Yahoo everything about your content and your website.
Compress the images and keep the file sizes light:
Page speed and loading time are two important factors in SEO. It's safe to say that heavily loading pages can affect your search engine results, so you should always compress your pictures and keep their sizes lighter than average. TinyPNG is a good and famous tool to compress the pictures.
Use a descriptive filename:
File naming conventions and stands help you locate the image files easily. Besides, they help Google find your image files and get them ranked properly. You should always use descriptive and comprehensive filenames that give your audience sufficient information about your content. You must include relevant keywords, product names, and photographer name, depending on the picture type you have used.
Structured data markup:
One of the significant things you can do for your image content and your website is utilizing the structured data markup. The structured data is another form of metadata that tells the search engines about the vocabulary you are using on your website. You may include the information about the categories of your site to show your image in search engine results. You must try Image Object, Image Vocabulary and Schema.org to describe your images and web content.
Use the right image format:
One of the most important things you should consider while optimizing the images is using the right format. The most valuable tools I have found online is the Google image decision tree. You should give a proper name to your image and keep its format like JPEG. PNG and GIFF are two other image formats, but JPEG is widely used and is more reliable than the others. Image optimization for SEO provides the extra boost you might need to get your pages ranked. You can optimize both your content and your images to succeed in your online business. You should always use the design principles to convey the right ratio of your pictures, videos, and text.
