Google Finally Rolls Out A New PageRank Update

Posted: 21 Jan 2011 04:13 AM PST

For those of you who thought this was the end of nominal PageRank updates, well, it was not. Google is rolling a new update right now. Some people started noticing it yesterday, and I believe the ups and downs will continue over the weekend.

The last update had been on April 2010, so around nine months ago. That is quite a long time, especially if you consider at some periods in the past Google would roll a new PageRank update every three months or so.

The PR on most of my sites hasn’t changed a lot. Some of my niche sites gained 1 or 2 points, but that was it.

Judging by the comments on online forums I believe this update has an upward trend, as most people are seeing increases in their PageRanks.

What about you, did you see any fluctuations?

Why Different Web Analytics Report Different Numbers?

questions and answers This post is part of the Friday Q&A section. If you want to ask a question just send it via the contact form.

Mayur asks:

Is the number of pages viewed on my site equal to the number of banner ad impressions I should have? Because my Aw Stats shows a higher number than the ad networks I work with. Google Analytics shows even lower numbers. What is the deal?

Welcome to the world of web analytics!

As you already noticed, each web analytics software, ad network and traffic estimation service (e.g., Compete, Alexa, Quantcast) will report a different number.

Why is that the case? Because what represents a unique visitor and a page view to your website is subjective (i.e., each service and software has its own criteria for deciding when a visit and a page load happens). For example, some services and software count search bots as visitors, while others don’t.

Second, different services and analytics programs use different tracking methods (e.g., JavaScript, pixel tracking) so not all visitor will be tracked equally. For example, a visitor with JavaScript disabled will not be counted by a service using JavaScript tracking, while it will be a service using pixel tracking.

Given all these differences and nuances, here are some rules of thumb most webmasters and online marketers use:

1. Raw logs are useless

Most servers store raw logs, which are lists of all the accesses and page requests on your website. It’s possible to interpret those raw logs with special programs, creating graphic reports which will contain the number of visitors, page views and so on.

Those numbers are grossly overestimated, though, because all kinds of search bots and automated queries are counted together.

2. Webalizer and AW Stats overestimate

Webalizer and AW Stats are very popular web analytics programs, and that is because they are usually installed by default on cPanel (the control panel software on most hosting companies). Both of them tend to overestimate the number of visitors and page views your website receives, however, and such data should always be used with a grain of salt.

3. Ad networks underestimate a bit, but there is nothing you can do about it

The number of impressions you’ll see on most ad networks control panel usually is an underestimation of your total traffic, and that is because they won’t track people who can’t see ads or who block them on purpose.

There is nothing you can do about it though, and if you want to make money using ad networks you need to play under their rules. The alternative is to have your own banners embed with HTML code, in which case they would be seen by 100% of your visitors.

4. Google Analytics underestimates a bit, but it’s the industry standard

The numbers reported by Google Analytics also underestimate your traffic slightly, and that is because the software has very strict rules regarding what should be considered a visitors and a page view.

GA’s tracking is very reliable, though, and that is why it’s used as the industry standard. If you want to sell a website, for example, most serious buyers will ask for Google Analytics data before they make an offer.

Summing up: Go with Google Analytics if you want to get a sense of your “real” traffic.
