Welcome to the Q&A Forum

Hi Teun, Thanks for writing in. I'm afraid that there isn't a way for us to index when a link was created, since a link could have been added to a site for several months before our crawler found the link and we have no way of knowing when it was created. The most recent index was processed between the beginning of May through the end of May, so we are just showing links that we found within that index time period. The indexes that were released in May are much larger than the index that was released in February, so it is likely that we are showing a lot more links from the most recent indexes than we showed from February's index because we were able to crawl more links through those indexes. I hope this clears things up. If you have any other questions about this, you can write into us at help@seomoz.org Thanks, Chiaryn
