We use a design strategy that delays the loading of photos until they’re needed by visitors. This means that pages load faster since thumbnails are only loaded when visitors move to that part of the page.
This is done using a technique called lazy loading. With lazy loading, instead of loading every image in a gallery, we only load information when a visitor reaches the area of the page where that content is found.
For example, we first load all the photographs located above the fold. As visitors scroll down, we continuously load additional photos—but only as necessary.
Although a few other website builders offer lazy loading designs, our code is optimized so that search engines are able also view textual content located anywhere on the page—even when that textual content is located in areas where images haven’t yet been loaded.
As a result, our highly-optimized lazy-loading thumbnail galleries perform extraordinarily well in search results.
