![]() Generally speaking, JPEGs are the best format for photographs, whereas PNG’s are best for line drawings, text, etc. So is JPEG always the right choice? Not at all. It has the smallest file size, and there is little to no noticeable difference in image quality between that and the other two images. You can see that the JPEG image is a clear winner. With that in mind, here is the same image as a JPEG, PNG, and GIF: Your task is to choose the most appropriate file type for each image-i.e., the one that offers the best compression with the least reduction in quality. Google has confirmed that it’s a ranking factor on both desktop and mobile. Images are often the largest contributor to overall page size, which can make pages slow and expensive to load. That means file sizes between the three file types can vary dramatically. Most images on the web are one of three file types: JPEG, PNG, and GIF.Įach of them uses a different compression method. So incorporating this into your alt text may help Google to understand that it is, in fact, an image of a product. Google knows what product we’re looking for based on a search for the product number alone. Want proof? Take a look at the related searches for this query: But it makes sense because Google clearly understands the relationships between product names and serial/product numbers. Google has no official guidelines stating that you should do this. For these, it can be useful to add the product or serial number, like so: You may wish to deviate from this formula slightly when writing alt text for product images. “This is a drawing of my cat, Mark, playing with his toys.“ ![]() “This is a photograph of a chocolate cheesecake.“ Remove any conjunctions or connections (e.g., a/an) from the resulting sentence and use the last part as your alt text. ![]() “This is a(n) image/screenshot/photograph/drawing of _.” However, here’s a shortcut that almost always works perfectly-finish this sentence: Matt Cutts gives some equally good advice for alt text in this old, yet still relevant video: Avoid filling alt attributes with keywords (keyword stuffing) as it results in a negative user experience and may cause your site to be seen as spam. When choosing alt text, focus on creating useful, information-rich content that uses keywords appropriately and is in context of the content of the page. Google uses alt text along with computer vision algorithms and the contents of the page to understand the subject matter of the image. Here’s their general advice for writing these: It’s used to show what a well-written alt tag looks like. That example comes straight from Google’s official guidelines. Browsers also display alt text if there’s a problem rendering images. It will also periodically scan for new images, which means there is no need to worry about slow and unoptimized images.Alt text (alternative text) describes an image. It’s what the browser displays to users with screen readers. It gives users peace of mind because they can restore an individual image or whole set of images with a press of a button.Īfter installing the Image Optimizer app, it will automatically scan all existing images and optimize them. The Image Optimizer app acknowledges this fact and, therefore, backups original images before making changes. Images are one of the most important assets of any store. The Image Optimizer app can convert images from PNG to JPG and dramatically reduce the file size up to 80% of the original size. The PNG format is only advisable for images with a transparent background. JPEG images are ideal for Shopify stores because they provide the best quality for the smallest file size (Note: Shopify automatically serves WebP images). The Image Optimizer app can automatically rename image filenames by using simple templates and, as a result, help the website rank higher on search engines. Descriptive, keyword-rich image filenames are crucial for image SEO optimization. The image file name tells Google the content of the photo and what the webpage on which it appears is about. Images can be a great source of organic traffic for a store if images are named correctly. With compressed images, store loading time, user experience, and SEO all improve. As a result, the time required for images to be sent over the Internet or downloaded is greatly reduced. The Image Optimizer app automatically compresses images to minimize file size without degrading quality to an unacceptable level. An image-rich store requires images to be as small as possible because oversized images take longer to load. In addition, Google is obsessed with page load speed and uses it as a metric to build its web search rankings. A faster loading storefront makes customers happier and improves the conversion rate. Website speed is crucial to positive user experience. Speed up Your Store, Improve SEO and User Experience!
