In order to make images indexable by search engines they must include relevant textual information. By describing images search engines get a better understanding of them and they are available for searchers with disabilities.
The filename of an image gives search engines an idea about the subject field and context of the image, so they should be correctly translated and to the point. Search engines also gather information from the content of the page, where the image is placed and from the image captions and titles.
Improved Image Search
We optimize image texts according to W3C’s web accessibility standards regarding image context categories:
- Informative images
- Decorative images
- Functional images
- Images of text
- Complex images
- Groups of images
- Image maps
Alt Tag for Screen Readers
Besides decorative images all images on your site should have alt texts that describe the information or function they represent. The browser displays this alt text to users with screen readers or if the images are not rendered for visual representation.
Depending on the function of the image, different text descriptions needs to be added. We optimize your images by adding or amending filenames, image titles and alt tags that are aligned with the respective image purposes.
Speed Up Your Website with Image Compression
Page load time is a crucial ranking factor, so it is important to choose the most appropriate file type for each image such as JPEG, PNG or GIF. An JPEG image has the smallest file size, and we help you choose the right format and comprise them in a pre-installed image compressor plugin or separate optimizer tool.
Get Featured in Rich Snippets with Schema Markup
Schema markup is microdata that you can add to your HTML to improve the way search engines show your pages in the search engine result pages. Schema markup is used by Google, Bing, Yahoo!, and Yandex.
We add schema markup for products, recipes, videos, and GIFs in order to enhance your click-through rate via more extensive rich snippets. It also influences image SEO as Google present relevant badges on the thumbnails in mobile image search results.
