Thanks for your comments. Clearly you aren’t going to be able to draw up an equation saying Income = some function of Authority, at least not with the data I used.

I’ll freely admit that there is bias in here six ways from Sunday. Did the bloggers report their income accurately, did Paula have selection bias when she picked which blogs to list, did I have selection bias when I decided which of Paula’s could really count as blogs and which couldn’t?

Luckily though I’m not submitting this analysis to any peer reviewed journal. Much more of a “Take a look at this chart” kind of thing

But if you have some specific suggestions you think might make this more useful, I’m happy to hear them.

Thanks!

this regression is useless. and yes, a linear regression would be better. and no, a higher R^2 doesn’t necessarily mean the regression is better.

Thanks for stopping by. Glad to hear that your revenue is starting to catch up with your traffic. It’s interesting to hear stories sometimes of how some people slog away and get a near linear increase in traffic over time, where others do something and get a lot of attention, catch a break and shoot in traffic.

Clearly the second category is more fun

Mubin,

You’re right. Technorati rankings have a better correlation. In fact they could have a linear aspect to them as a site will be able to quickly shoot up in the rankings with a few incoming links when it is new, but established sites need much more to move from say, 200th to 150th. Between that and Alexa rankings I think that I have found fodder for another post, probably next Saturday

And you’re right, I believe my income is really catching up with my pageviews, which, by the by, are on target to hit 100,000 pageviews with 54,000 uniques for the month of May 2007. (Thank the Lord for that viral post!)

And you’re also right about places like GPSReview finding a good product blog niche.

I’m totally getting into that, too, setting up niche sites while keeping my regular blog.

I’m really geeked about it all now that I finally found Blogtrepreneur’s simple instructions on how to set up a dot com.

Thanks for the link love.

Great piece,
Paula

:). And when I meant rank I was talking about technorati rank, not Page Rank.

Page Rank is good for nothing EXCEPT selling links.

Yes, I definitely agree that moving past the Page Rank 6 range is very very difficult.

I would welcome such an analysis and actually considered doing it here. The problem of course is that the traffic and page view stats aren’t as frequently published as earnings, and might require e-mailing various bloggers to get.

However if anyone wants to leave me some numbers, or a link where they posted it on their blog, I can be sure to include it in a future post.

Alternatively of course we could use Alexa traffic rankings, which might make for an interesting analysis. Perhaps next weekend I can do that, unless another blogger jumps the gun.

I also looked at the blog PR while I was doing the analysis, indeed that is in the data chart at the bottom, but found it doesn’t discriminate quite enough for my intent

The problem with PR is that it seems as though many blogs get clumped at 6. In fact only one blog on my list had a PR above 7, and that wasn’t even a super earner.

You can see a chart of that on my published Google Docs

I suppose that I could use one of the PR estimation tools to try to get a fractional Page Ranking which might be worthwhile.

Anyways, thanks for stopping by.

This could give us the productivity index. I would not be surprised to see some few blogs with astonishing page views and visitor traffic, but abysmal income of $500 monthly blog incomes.

Keep up the good work.
