What does TinEye crawl date mean?
TinEye’s reverse image search engine searches the web using an image and shows you where the image appears online. The search engine results page includes some useful information about your search; including sorting options, a compare feature and the TinEye crawl date.
You can start by sorting your results:
TinEye’s results page includes links to webpages, on which your search image appears. The compare feature allows you to compare results with the image used to perform the search. This is extremely useful when identifying cropped, resized, skewed or photoshopped images.
Search results also include information about our crawl date. The TinEye crawl date is the date the image was found by TinEye’s web-crawlers. If you find two similar images with different crawl dates, this means that our web crawler found and indexed the images separately, on two different dates.
For example, this photo was taken on July 21, 2008, but the oldest TinEye match is from October 31 2009.
Sometimes, TinEye users are interested in finding out the first time an image has appeared on the web. However our TinEye crawl date is not really a perfect indicator of that, it really only is the date when our crawlers encountered the image on the web. The TinEye crawl date can however be very useful when you are doing image verification and find out that the news or event image you are verifying portrays a news event in 2014 while using a photograph that TinEye has crawled in 2012!
