Images can make a website clearer, more persuasive and easier to trust.<\/p>\n
They can show products, explain services, support blog content and make a page feel more polished. But images can also cause problems if they are too large, poorly chosen or added without any thought for accessibility and performance.<\/p>\n
Image optimisation is about finding the balance between visual quality, speed and usefulness.<\/p>\n
Every important image should earn its place.<\/p>\n
For an ecommerce website, that might mean clear product photography from several angles. For a service business, it might mean real team photos, examples of work, diagrams or images that help explain the process. For a blog post, it might mean a relevant featured image or supporting screenshots.<\/p>\n
Avoid adding generic images just to fill space. If an image does not help the visitor understand, trust or act, it may be better left out.<\/p>\n
Different image formats suit different jobs.<\/p>\n
JPEG is still common for photographs. PNG is useful for graphics that need transparency, though it can create larger files. SVG works well for simple logos and icons. WebP and AVIF can often provide smaller file sizes while keeping good quality, though you should make sure your website handles them properly.<\/p>\n
Most modern website platforms and image tools can help create suitable formats automatically. Avoid uploading huge uncompressed files straight from a camera or phone and assuming the site will sort them out.<\/p>\n
Large images are one of the most common causes of slow web pages.<\/p>\n
If your website displays an image at 900 pixels wide, there is usually no need to upload a 5000 pixel version. Resize images to sensible dimensions and compress them so the file size is as small as practical without making the image look poor.<\/p>\n
WordPress and many ecommerce platforms can create multiple image sizes, but you should still start with sensible uploads. Image optimisation plugins can help, but they are not a substitute for good habits.<\/p>\n
Alt text describes an image for people who cannot see it and helps search engines understand how the image relates to the page.<\/p>\n
Good alt text should be short, descriptive and relevant. It should explain the image in context, not repeat a list of keywords.<\/p>\n
For example, "woman choosing running shoes in an online store" is useful. "shoes trainers running shoes buy trainers cheap trainers best trainers" is not.<\/p>\n
Some images are decorative and may not need descriptive alt text. Important images, product images and instructional screenshots usually do.<\/p>\n
Filenames are easy to overlook.<\/p>\n
A name such as Keep filenames short, descriptive and plain. Use hyphens between words and avoid stuffing in every possible keyword.<\/p>\n The image shown when someone shares your page on social media is not always the same image that appears in the article.<\/p>\n For important pages and posts, set a suitable social sharing image through your SEO plugin or website platform. This helps your page look more professional when shared on Facebook, LinkedIn and other platforms.<\/p>\n Choose an image that still makes sense when cropped or displayed as a small preview. Avoid tiny text inside the image, as it may be unreadable in a feed.<\/p>\n After adding images, test the page.<\/p>\n If the page feels slow, review the largest files first. You may need better compression, lazy loading, a content delivery network, improved caching or a hosting setup that is better suited to the site.<\/p>\n Image optimisation is not only a design task. It affects user experience, search performance and conversions. A website with sharp, relevant, fast-loading images is easier for visitors to use and easier for the business to maintain.<\/p>\n","protected":false},"excerpt":{"rendered":" Good images can make a website more useful and engaging, but they need to be chosen, compressed, named and described properly so they do not slow the site down.<\/p>\n","protected":false},"author":1,"featured_media":1671,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4],"tags":[],"class_list":["post-1672","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-general"],"_links":{"self":[{"href":"https:\/\/www.4uhosting.co.uk\/articles\/wp-json\/wp\/v2\/posts\/1672","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.4uhosting.co.uk\/articles\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.4uhosting.co.uk\/articles\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.4uhosting.co.uk\/articles\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.4uhosting.co.uk\/articles\/wp-json\/wp\/v2\/comments?post=1672"}],"version-history":[{"count":7,"href":"https:\/\/www.4uhosting.co.uk\/articles\/wp-json\/wp\/v2\/posts\/1672\/revisions"}],"predecessor-version":[{"id":3919,"href":"https:\/\/www.4uhosting.co.uk\/articles\/wp-json\/wp\/v2\/posts\/1672\/revisions\/3919"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.4uhosting.co.uk\/articles\/wp-json\/wp\/v2\/media\/1671"}],"wp:attachment":[{"href":"https:\/\/www.4uhosting.co.uk\/articles\/wp-json\/wp\/v2\/media?parent=1672"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.4uhosting.co.uk\/articles\/wp-json\/wp\/v2\/categories?post=1672"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.4uhosting.co.uk\/articles\/wp-json\/wp\/v2\/tags?post=1672"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}blue-running-shoes-side-view.jpg<\/code> is more useful than IMG_4827.jpg<\/code>.
