I have a website that has two different Alexa rankings as follows:
1) The public ranking on Alexa siteinfo page of the website, that is the usual ranking page and it indicates a rank of 318,254 which they claim it is updated daily.
2) Another public and daily ranking of the same website but it is viewable using either the freely available list for Top 1,000,000 Sites in this page at the almost top right or using StatsCrop website and this ranking indicates a rank of 253,753.
Which one is more accurate? Why different daily rankings?
