Alexa vs. Netcraft
Since there are no exact number of toolbars installed for each of them, we can’t really tell which is more reliable.
However, I think we can verify this by comparing both rankings agaist the site’s published traffic.
Under Netcraft, we have the top 6 below:
1. Sun.Star – 2,518
2. Daily Inquirer/GMA – 3,320
3. newsBALITA – 4,989
4. Philippine Star – 5,580
5. ABS-CBN – 10,029
6. Manila Bulletin – 11,549
With Alexa, we get another set:
1. Daily Inquirer/GMA – 3,179
2. Philippine Star – 8,645
3. Manila Bulletin – 21,670
4. ABS-CBN – 22,247
5. Sun.Star – 38,562
6. Abante Tonite – 46,993
From what I know, Inq7.net should lead the pack with a total monthly pageviews of 41 Million. Marites adds that newsBalita gets 2 Million pageviews/month. Maybe Max will share how many pageviews Sun.Star gets.
Again, I will go back with another info about MySpace having more pageviews than Google. In that list, Yahoo leads the pack at 43.7 Billion pageviews and Alexa correctly ranks it at #1 while Netcraft puts it at #2. Google is #2 on Alexa but #1 on Netcraft. While both Netcraft and Alexa was not close to Google’s actual ranking in terms of pageviews, Netcraft overly underrated MySpace to #85 as compared to Alexa’s #8.
From the figures above we can tell that Alexa is more accurate in predicting rankings. Yes, both may be unreliable but both have a good sample size (in the millions) of the total population.
