Image optimization is an essential practice that involves reducing the size of images while maintaining their quality, making them more accessible and efficient for web use. Search engines consider image optimization as a crucial ranking factor in search engine results pages (SERPs), making it necessary to understand this process.
Here are the answers to some popular questions about image optimization:
Alt tags are HTML attributes that provide text descriptions of images. If the image fails to load, alt tags show up instead, helping users and search engines understand what the image is about. Alt tags also enhance accessibility for visually impaired people who use screen readers, making it a crucial aspect of image optimization.
Large file sizes slow down your website's load speed, consequently affecting both user experience and search engine rankings. Compressing images reduces their file size without compromising quality.
Responsive design is essential in image optimization as it ensures that images resize based on the viewer's device screen size. Images that are too large or small can impact the website's mobile-friendliness and negatively affect user experience.
Page load speed plays a crucial role in SEO, impacting user engagement and conversion rates. Optimizing images reduces their file size, reducing page load time, which helps improve user experience and your website's rankings.
Having optimized alt tags, descriptive file names, compressed file sizes, and using responsive design make images SEO-friendly. Including relevant keywords within alt tags can also improve your website's visibility in SERPs.
To optimize images for SEO using markdowns, use alt tags by inserting descriptive texts within square brackets [ ] immediately followed by a URL of the image enclosed by parentheses ().
When it comes to file size optimization, try to reduce the image file size without compromising quality, especially for large images. Additionally, ensure that your images are responsive and adapt to the viewer's device screen sizes.
