How To Rank High In Google Image Search

When you search for images at a search engine, do you ever wonder why some pictures show up before others? You care about how your website ranks on Google, now it’s time to care about how your images rank, as they can be an important source for site traffic.

Google can index types formatted as BMP, GIF, JPEG, PNG and WebP as well as SVG. How does Google know if an image is about coffee and not about tea?


Deciding what images are associated with which queries first depend upon a search engine associating images with keywords that might be used as search queries. A web crawling program travels through the web and aggregates images and text that appears on the same images as those images. It might take all of the text from those pages and store it in a database, or text that is only a certain distance away from the pictures. It might also look for text that is associated with an image, but is found on different pages. Ranking factors are then used to determine the relevance of a picture to the query, and the order that these associated image are presented to a searcher.

What are the best practices for image optimization?

  • Alt Text

Instant recognition isn’t possible for search engine spiders at this time, instead you must help the spiders understand each of your images with alt text. It’s the text that the search engines use to understand images.

  • File Size

Do not let your browser resize a large image to look smaller. To solve this always use an image editing program to make your image a desired size and upload that.

  • File Name

Pick a descriptive filename-preferably a file name you want that image to rank for-because it helps with your search engine rankings.

  • Captions

There is no direct relation between mage captions and search engine rankings, however bounce rates are taken into account. Next to your headline, image captions are important because they are one of the most well-read pieces of content on your entire site.

  • Frequency of an image within a website

The number of times that an image is used on the same website might influence the ranking of that image for certain keywords, both positively and negatively. This could be an image used on more than one page or on the same page more than once.

  • Other Ranking Factors

a)     Total number of images on a page.

b)     Total number of image that are linked to by particular page.

c)      Total number of thumbnail images those are located on the same webpage as the ranked image.

d)     The total number of links there are to the URL of an image.


As far as regular web searches, Bing and Google both present a number of options for users to refine their searches. Bing of course has the explore window, which for many queries, provide multiple categories. Google has its search options, images are included in that. Many have experienced the disappointment of finding their own images outranked on Google image search by someone else who has used the same image. Employing the techniques can help Google determine your use is the most authoritative and rank your image higher.
