Alexa just announced they’ve changed to a new algorithm in computing the web rankings. Previously, Alexa only relies on its toolbar to gather site usage data to perform web rankings. They’ve added more sources now to improve the metrics but have not revealed what these are.
The new rankings have been rolled out today and a lot of sites have drastically been affected. And though Alexa rankings is by no means any great indicator, a number of ad networks and advertisers use this data to determine ad rates.
Locally, we’re starting to see shifts on the top sites in the Philippines. Last January, I noticed the two online gaming sites Level-Up and eGames fighting for the top spot, leaving behind long-time leader Inquirer.net.
Here’s how the new Alexa data has changed all that:
inquirer.net : 3,034 (new) from 2,638 (old)
gmanews.tv : 4,030 (new) from 4,451 (old)
sulit.com.ph : 4,033 (new) from 3,195 (old)
mp3-codes.com : 4,731 (new) from 2,950 (old)
levelupgames.ph : 5,161 (new) from 1,829 (old)
ebay.ph : 6,585 (new) from 2,875 (old)
philstar.com : 5,665 (new) from 5,344 (old)
pep.ph : 6,268 (new) from 4,900 (old)
tipidpc.com : 6,794 (new) from 2,735 (old)
e-games.com.ph : 10,151 (new) from 2,650 (old)
