Images should support your messaging and build trust — which is why we select them after strategy and copy are locked in. Every image we use is optimised with alt tags that describe what it shows, making it discoverable in Google Images and accessible to vision impaired visitors. Done right, images reinforce your message and contribute to your overall search rankings.
WebP is currently the best choice for website images — 25-35% smaller than JPEG or PNG with no visible quality loss, meaning faster load times and better rankings. AVIF is emerging as the next generation format with even better compression. For video, WebM delivers high resolution with fast loading. At Digital Assassin, modern file formats are standard on every build.
Video is one of the most engaging content formats — but only if it loads fast. We use WebM, supported on our CoreDNA platform, which delivers high resolution video with significantly faster load times. Page speed is a core Google ranking factor measured through Core Web Vitals. Faster pages rank higher, keep visitors longer, and convert better — video done right ticks all three.
Alt text was designed for vision impaired users — and that should still be the goal. Describe the image accurately and naturally, incorporating a relevant keyword only where it fits. "Melbourne digital marketing team reviewing campaign results" is far stronger than "team" or keyword-stuffed alternatives. We audit and update alt text across your entire image library as part of our optimisation process.
It's not the number of images — it's their impact on load time. Most users abandon a page after three seconds, so every element must earn its place. Pages need enough text to rank in search and AI, so balance is essential. Increasingly, well-optimised video in WebM format delivers higher engagement with faster load times — making it the smarter choice over static images.
No — image and video optimisation is one factor among many. Google needs to assess your site's authority, the value and clarity of your content, accurate and comprehensive Schema markup, sitemap submission, and Core Web Vitals performance — before it even notices you. Each element builds on the others. That's why piecemeal fixes rarely work and a complete strategy always outperforms them.
