Seems like PR has a real value after all (Putting Matt Cutts' words to the test)

Is it a good thing if google crawl your site more?

 

Yes of course, your new pages will be indexed faster.

 

If you have time critical content, e.g. news, being crawled more often means making your content available for a bigger audience before it turns into old news.

 

I would love to see this example if you are willing to share it - if you want to keep it private then maybe a PM?

 

you are failing to differentiate between real PR and toolbar again aren't you?

real PR affects both rankings and crawl rates, toolbar PR is used to make your site look unattractive for link sales, they can manipulate it separately from real PR, hence rankings remain unaffected.

they did so in several well publicized cases with the link sales penalties a while ago, lots of toolbar PR drops, nobody noticed any rankings differences or traffic reductions.

they can also prevent your site from passing linkjuice too, but it still doesnt affect the actual sites rankings.

however if you lost all your IBLs, and hence your real PR, I promise you that you would notice that in your rankings

 

I know pagerank affect crawling interval .Low pageranked site google bot visits often

 

I concur with SEOibiza.

The toolbar means diddlysquat.

 

Could any body tell how difference will be crawl rate for pr2 and pr3

 

No They Can't.

It would be purely hypothetical because nobody knows what the true PR value is so you cannot apply the crawl time to a numerical value for the calculation. (other than Google).

 

If you are looking for hard numbers: Sorry, no. But if you look at the graph comparing PR and hits, you'll find, that a PR 3 website (which could be anything between 3.0 and 3.9) with a low update frequency gets visited about once per day. My estimate for PR 2 would be once in two days. If you happen to have such a site, why not simply do your own analysis? The tools and methods for doing this are provided in the blog post.

 

Hi blackonyx - I wondered, what evidence do you have that says a toolbar pr of 3 equates to anything from a 3 to a 3.9 in real toolbar metrics?

 

None.

Thats a mathematical conclusion drawn from the thought, that real PR is mapped to toolbar PR and rPR is much more fine-grained than tPR. No matter how you do this mapping, you inevitably end up with implicit or explicit decimal places in the tPR, which have to be either rounded or cut off in order to get a natural number.

If we see a toolbar PR of 3, it can be anything from a solid 3 to borderline 2 or 4. I just used the decimals to put this into words.

It would have been unscientific for me to state, that a PR of 3 equals about one visit per day, while a PR of 5 results in 3 without acknowledging that both values might be borderline. That is, if someone else might check my results s/he might come up with slightly different numbers. In other words: This is about making my experiment reproducible

 

You are totally wrong, but in your own words

 

PR affects crawl rate that is so true in any basis...

 

The reason I posted was in our industry we obviously have to try and assert some values to enable conversation and discussion, the problem comes when we assert certain values to be facts when they are assumptions.

A toolbar PR of 3 could actually be a 1 or a 5 in real terms and often is, assuming of course that Google exports Toolbar PR based on real PR values then we see Toolbar PR jumping 2 points easily, we know for fact that the export is often weeks behind when real PR is updated. this means that your calculations are based only on assumed PR and that the assumptions overlook that real PR is not only updated weeks and months ahead of the toolbar but that also the variables are often beyond a single point drop or rise.

That is why I believe you cannot estimate or calculate with any accuracy that is of any factual value, that is because you dont know what the real pr value is as a starting point and it is often more than one point out of toolbar PR.

That said of course we have to be able to discuss the subject and try to use some assumed value so I am not knocking what you have done, in fact my mind is not clever enough to put a tool together to start with, I just think we have to be careful about the way we present this sort of data.

 

I understand your concerns and you are right to point them out. I had roughly the same thoughts, when I put my experiment together. As stated in my blog post, I chose those two domains for a reason.

I am well aware, that toolbar PR always lacks behind. For this reason, I chose domains, which do not update very often in order to minimize effects of new backlinks and also sampled them for nearly two moths.

I can assert for a fact, that Toolbar Page Rank has positions after the decimal point, which are not shown. Thats just something that always happens in one way or the other, if you map a larger range of numbers onto a smaller one (according to it's definition, real PR is guaranteed to be of a larger range than 10). What I cannot assert (and never did) is an even distribution, e.g. stating that 3.5 is a "solid" 3. When I said 3.0 and 3.9 are borderline, these two values should *not* be taken as literal numbers, but as symbolic borderline values.

Nothing I presented should be taken as hard, factual numbers. My findings should all be considered to be trends and always (and only) considered in conjunction with my outline (thats why I hesitate to copy and paste my "study" here)

 

G has not stopped the madness. I'm looking at it right now in my toolbar.

What would you recommend when it comes to increasing your PR?
