Optimize Images for Fast Sites
In the post "How to [Optimize] Your Page Images to Increase Site Speed," Matt Owen writes that Google keeps track of how well marketers' site speeds are keeping up with those of their competitors. Search engine ranking logically follows. Also, Google says every second of Walmart.com's site speed improvement raises conversion rates by 2 percent, Owen writes in the April 26 article.
But images are, by far, the biggest drag on site speed, his pie chart shows.
A few bits of advice for marketers from Owen include:
- Resolution Can Decrease on the Web. Check image sizes, which isn't just going into Photoshop and making images smaller, he says. For example, if a marketer uploads an image at "1024 x 683 pixels" the marketer can reduce the resolution, because "the user will only ever see it at a maximum of 420 x 289, less than half the upload size."
- Marketers Should Consider Whether They Really Need Particular Images. Owen cites a quote: "The fastest HTTP request is the one not made.”
- If Images Contain Text, Consider Removing It and Adding the Font Yourself, "and use vector graphics or CSS for things like logos or shading on the page," he says.
- Marketers Can Consult More Guidelines From Google. Google has a page devoted to the task, as does Christopher Ratcliff of Search Engine Watch.
