Just curious as to if anyone else uses this code in their sites, such as iwebtool and others. I was thinking of putting it to use, I see a few people selling sites here that utilize this code, even some selling the code.. maybe some feedback on this would be nice...

Thanks in advance.

there is also the source of the up to date code for perl

it is a free code, just looking for feedback on it...

[rehash]

I dont think google agrees with these tools, if they would, then it would have been much simplier, but the way there are, it's pretty obvious someone did reverse engineering on the toolbar which is pretty much illegal

[mad4]

As far as I know this is the only way to get the PR of a page from google.

Also pretty sure that this is how the keyword tracker tool must work (as there isn't really another way).

Sorry, which keyword tool are you talking about? The one here at DP?

This code is confusing...Could the thread starter provide some reference to its origin or a URL duscussing it further?

[mad4]

Sorry, which keyword tool are you talking about? The one here at DP?
Yes, and probably any other scripts that do the same.

If google wanted to stop this script working they could quite easily. Or they could make it part of the API.

I was reading this post (http://www.jimwestergren.com/google-rk-as-internal-live-pagerank-pr-evidence-findings/) about an RK value being passed in the google results XML feed which may be the actual up to date PageRank.

[mdvaldosta]

I think the latest PR flux has disproved the theory that RK means current pagerank.

[toby]

Isn't that those scripts illegal? Is it okay with Google?

Your not supposed to pull PR without using the API. Any server that runs PR checking code without using the API runs the risk of having that server (IP) blocked from requesting PR in the future. It happens on occasion with those running directory scripts that check PR as well as some SEO software.

[mad4]

Your not supposed to pull PR without using the API.

But is there a way to get PR using the API?

[mdvaldosta]

Yea the directory scripts, like phpld, do it.

[mad4]

Quote from David (http://www.phplinkdirectory.com/forum/viewtopic.php?p=9942&sid=5a3de05e1e8460092f63234686920d7c) the owner of phpld on his forum a few weeks ago.

Google API does not give pagerank, and Google forbids automated queries to their server. So that is why it is best not to do it from your webserver, especially automated queries that check pagerank for multiple sites at once.


It looks like phpld uses the script discussed above. dvduval is the owner and is on this forum I think.........

[miles]

It happens on occasion with those running directory scripts that check PR as well as some SEO software.

Do you remember where you saw an example of a site deploying a PR checking tool, or even a mass data center PR checking tool, and then getting banned? Everyone is runnng it. Seochat for one.

If google wanted to stop this script working they could quite easily.

How do you figure? I mean there are a million sites running this toolbar hacked code and not a lot G can do about it from where Im standing. My guess is it will be imbedded in the API very soon as you point out - In fact I would be very surprised if it isn't this RK value after all.

[wannaknow]

Can anyone please give a link to future pagerank/pagerank prediction php script ? I mean the actual source code, not a site providing such a service.

[ThomasSchulz]

Check the first post in this thread...? The code is in an iframe.

[mirainfo]

Hey Guys, Is it bad to query google for this? I thought this is not illigal.

[wannaknow]

Check the first post in this thread...? The code is in an iframe.

I was asking for PR prediction script, not current PR detection.
Also, if anyone has php scripts of backlinks/alexa checking, etc - i will greatly appreciate that.

[mad4]

You can't predict pagerank, there are no reliable scripts to do this.

[desyman]

did anyone tracnscript it to jsp yet ?
was looking for it for a few weeks, but no success.
php is good, but need it in jsp.

can do it on my own, but need extra couple hours, which i have not

[enampwd]

I am using a php script which is similar to the above script. I have collected it from internet. But I forgot from where.

you cant expect people to do work for you! i know of no jsp version

[MadroosterTony]

becaure of your server php config, it will not always return the correct page rank, based on some of the php modules installed or not installed.

[BIGC]

ya its a good script ...

[vic_msn]

this script is used in phplinkdirectory to check PR

[georgiecasey]

Does this still work?? I keep 404 forbidden messages

I use something similar, but I have it inside a Flash movie so that it doesn't bring you to a new page, it just posts the rank in the movie very quickly.

This one still works without any problem. Check whether your webhosting service supports CURL. I tried to run in the server which dont have CURL compiled PHP version and I got all PR as 1. Then I tried in the server having CURL installed and got the correct PR. you check in this area. Good luck :).

What is that??

[MaxPowers]

I have been using this PR script for well over a year on various sites. For one, I cache requests for the same URL for 24 hours to reduce the load of queries to Google.

now I want to check PR on 20,000+ domains per day...

Is there a legitimate way?

The demand for PR on webpages is higher than ever and being incorporated into many diverse apps. Perhaps Goog ought to consider de-centralizing the listings to reduce performance hits on their main server... or offer a dump like odp does...

Reduces their brunt of the load and satisfies the appetites of hungry developers.

[master06]

i changed my server. New server cpu 64 bit so i have got some code problems. i need this script 64bit vers.

Regards,
Mustafa

[srucnoc]

Does anyone have a srcipt that checks PR using an API? I'd like to see how that code works

[mad4]

You can't check PR using the Google API. The only way is the code at the start of this thread.

[azizny]

Just incase no one noticed, this script doesn't work nor reflect Google's actual PG.

I tried it couple of months ago, for example try some links with the site TorrentGuy posted:
http://www.everyscript.de/PRank.htm

and you will see my point, his page is pageranked 4, but the script returns 0!

Peace,

[master06]

ok i find 64 bit edition version and i develop it. now works great.

[Ali_GGL]

Hi Torrentguy
i have used your code to utilize it for my website and i when entered a url to it its giving me a ch: 6537457445 number i think it is not page rank or may be i am not utilizing it right so please guide me how to utilize this code for my website.
Thanks.
Ali.

[smartneil]

[ravi72194]

code is not working..

[softgroups]

code is not working..

yes you are very right...

[cchetanonline]

i need such script
can any one please tell me from where i will get this type of script for free

i think the current which is given heere is not working

[00johnny]

Guys the script is 2 years old just like this thread, i'm sure its obsolete by now

[Bryce]

The one here...

http://v1.magicbeandip.com/mbd-file/PageRankReport.php

works fine. The only problem is no PR checker works absolutely correct during updates.

If anybody is interested in purchasing a javascript version, PM me....

[chandan123]

digitalpoint.com -1
yahoo.com -1 :eek: so u want us to purchase this :D

[richard.feakes]

[Findfair]

[kmr909]

[superds]

This script hits the url that Google Toolbar is using. Google will not track that request is generate either from Toolbar or via website. But it against Google terms and conditions.
