Optimizing images is one of the most effective ways to improve your website’s load times and 横浜市のSEO対策会社 boost your search engine rankings
Page delays drive visitors away and negatively impact your SEO standing, since speed is a core metric for search engines
Images often make up the largest portion of a webpage’s total size, so compressing and formatting them correctly can make a big difference
Start by choosing the right file format
For photographs and complex images with many colors, use JPEG because it offers good quality with smaller file sizes
PNG shines for images with transparent backgrounds, minimal color ranges, or sharp edges
WebP delivers up to 30% smaller files than JPEG or PNG while preserving visual fidelity
Most modern browsers support WebP, so it’s worth converting your images when possible
Next, compress your images before uploading them
Numerous free utilities, both web-based and desktop, can shrink images with minimal perceptible loss
Consider using TinyPNG, Squoosh, ImageOptim, or Kraken.io to automate optimization
Upload only the dimensions your site actually needs—larger files only slow things down
Implement srcset to serve appropriately sized images based on screen resolution
Tailoring image sizes to device screens reduces load times and improves mobile UX
Lazy loading reduces initial page load by only fetching images when they’re about to be seen
Most modern browsers support native lazy loading with the loading=lazy attribute
Don’t forget about alt text
Alt text informs search crawlers of image content, boosting visibility in image-based queries
Write clear, descriptive alt text that includes relevant keywords naturally, but avoid stuffing
Finally, use a content delivery network to serve your images
CDNs store copies of your images on servers around the world, so users download them from a location closer to them
This reduces latency and makes images load faster regardless of where your visitors are located

By taking these steps, you’ll not only make your site feel faster and more responsive but also improve your chances of ranking higher in search results
Consistent, smart image management transforms site performance and search engine outcomes
