Image Optimization

Image Optimization

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 loading, which increases user engagement and search engine rankings.

Image optimization is the process of creating and delivering high-quality images in the ideal format, size, and resolution to increase user engagement. It also involves accurately labelling images so search engine crawlers can read them and understand page context.

Steps To Optimize Your Images

Resize your images

Image size and file size are not the same thing. Image size refers to the dimensions of an image (e.g. 1024 by 680 pixels). File size is the amount of space needed to store it on the server (e.g., 350 kb). Ensure you pick the right file format. PNG, JPEG, and GIF are all popular. Each has its benefits. We recommend JPEG for images with lots of colour and PNG for simple images.

Choose the right compression rate. If you compress an image too much, the file size is small but the image quality is poor. On the other hand, when you use a low compression rate, the image quality is high but the file size is huge.

If you don’t have Photoshop, here are some popular tools – Tinvjpg. Pixlr (JPEG optimization), or Kraken (bulk compression).

Optimize image file names

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. File names should make sense to both search

engines and humans. For example, the original name for an image of a woman in a hair salon is “salon234.jpg.” Rename it with a clear and more descriptive title such as “woman-having-a-haircut-in-a-salon.jpg.

Use alt tags

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.

While no ideal number of words exists, aim for 10 to 15 to convey something about the image.

Optimize the image title

Image titles are less important for SEO, but they can provide additional context to the alt text. Image titles are more helpful in terms of user engagement. Consider adding a brief call to action such as “buy now” or “download today.”
