Before uploading images to WordPress, utilize tools like TinyPNG to compress and optimize image files, reducing their size without compromising quality.

2. Content Delivery Network (CDN)

Integrate a CDN with WordPress to distribute images across servers globally, ensuring faster delivery to users regardless of their geographical location.

3. Lazy Loading

Implement lazy loading techniques to defer the loading of images until they are within the user’s viewport, reducing initial page load times.

Vl. Alt Tags for Accessibility and SEO

Importance of Alt Tags

Alt tags, or alternative text descriptions, provide textual descriptions of images. They are crucial for accessibility, allowing screen readers to describe images to visually impaired users. Additionally, alt tags are vital for SEO, as search engine crawlers rely on them to understand the content of images.

Impact on SEO

Failing to include alt tags or using poorly descriptive alt tags can negatively impact website SEO. Search engines may penalize websites for lack of accessibility and poor optimization, resulting in lower rankings in search results.
