SEO Guidelines for Media
Images are crucial to ensuring that your content is more accessible, attractive, and engaging to users, but they’re equally important in terms of SEO.
First, they give search engines important contextual information. Second, optimized images speed up page, which increases user engagement and search engine rankings.
To give Novozymes, the best opportunity to succeed with SEO, you should understand the basics of image optimization.
There are three main steps to follow to ensure your images are optimised:
1. Resize your images
Make sure your images are the correct size and weight. Read more about the media specs required for our website here.
2. Name your image files correctly
Choosing the right file name is important for your page SEO and for ranking in image search results. Before uploading any image, name the file with relevant, descriptive keywords to get the most SEO power.
Include target keywords at the beginning and separate them with hyphens. Don’t use underscores because search engines don’t recognize them and won’t be able to “see” the words individually.
File names should make sense to both search engines and humans. We have implemented a naming convention for ease of reference.
Industry – application/page name – short description of content of image
For example, the original name for the image above was “corn234.jpg.”
The correct name for the file would be: Brewing-cereal-cooking-corn-field
Use numbers if you have multiple images with similar content on the same page.
Brewing-raw-material-optimization-cereals-01
Brewing-raw-material-optimization-cereals-02
3. Remember to input the "Alternative text"
Viewers may understand what a picture is about, but search engine spiders still need clues. Without alternative text, it’s impossible for search engines to accurately index your image content. A good alt tag provides context and helps visually impaired users too. Even when images aren’t loading because of a glitch, search engines can still read the alternative text to help rank a page. Brand-relevant words can be included here to boost visibility. Just avoid keyword stuffing.
Provide more detail than you included in the file name. While no ideal number of words exists, aim for 10 to 15 to convey something about the image.
