Image Optimization Secrets to Boost Page Speed and SEO > 자유게시판

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
