that's great!!! :)

Lol, that's great!

nice one philipp. very funny!

cool algo ;) that's how we perceive it to work :-D

hahahah.. this is funny

"// W3C sux! "

Philipp--how could you share me personal info – in public!!!!!

"recipient = "peterhomelandsecurity.gov";"

You missed a bit of code right at the end...

// removed by request. 2004-04-24.
// if (owner(url) == "Josh") {
// pagerank = 100;
// }

// added 2004-04-24 – this should be a nice surprise for her...
if (owner(url) == "Diane") {
pagerank = 100;
}

55 Ways readers should understand that... ;-)

I'm a Perl guy instead of PHP, but I think there is a bug at this line:
   pagerank += countBacklinks(url) / 10000
as I didn't see a limiting upper bound – add this snipper after that:

if (pagerank > 10) {
   if (pageHostedOn(url, 'outer-court.com')) {
   setInternalSecretPageRank(pagerank);
   // Larry says Philipp writes good s**t about us – reward him
   }
   pagerank = 10; // Highest we show externally
}

And I wonder if this was recently added:

if (pageHostedOn(url, 'w3c.org')) {
   setInternalSecretPageRank(-100);
   // W3C sux *and* sells link – penalize those bastards!
}

Hee hee.

The comments around the China censorship code might be VERY interesting!

Philipp, why don't you relase it under GNU GPL? ;)

Does not compile!

if (inString(content, "tiananmen")) {
   if(pagerank > 6){
   pagerank -= 6;
   }else{
   pagerank = 0;
   }
}

This is an addition to Google China's algorithm.

Perfectly done! as always.
I wonder how can you come with something that special everyday!!

keep surprising us ;)

Other things you may be missing:

// Larry <3 Marissa 4Ever 2004
if (secretSemanticAlgorithm (content, "Marissa Meyer") == ROCKS) {
   pagerank *= 2;
   addtoInternalSecretPageRank(500);
}

// Best project at the best company ever – NW
if (secretSemanticAlgorithm (content, "Niniane Wong") == ROCKS) {
   pagerank = ceil (pagerank * 1.5);
   addtoInternalSecretPageRank (200);
}

// NOTE: Don't tell W3C about Semantic Algorithm, it might
// cut into Adwords sales – Sergey

Nice work Philipp!
Now, let's rewrite it into other programming languages :-)

lol. great idea Alek :p

> I wonder how can you come with something that special everyday!!

Thanks, blame this one on Alek :)

Philipp, as typical, is too generous – I sketched a rough idea, but as with most things, implementation is key ... and it's his PHP code – well done as always Mr. Blogoscoped.

Just be glad I didn't write it – my Perl code is often not even understandable by me! ;-)

Just translated half of the script into PHP, continue tomorrow, crack the "Google Algo", haha ;)-

Heh. Funny.

Is "XhtmlValidator.php" for real?

Yes, no kidding.

That's Beautiful.

Yo Lar Am I on the Hatelist.

Awesome! lol

hilarious!

Nice post Philipp!!!

digg for it: http://digg.com/software/If_Only_We_Knew_Google_s_Secret_Ranking_Algo

Bool Gbot=0N;

if (pageSearch(url) == "Microsoft") {
Gbot=OFF;
}
else {
Gbot=ON;
}

Awesomely awesome. Good job!

What this post highlights to me is: The urgent need for an open source search engine that really works and is really popular.

Why didn't all the open source search engine projects didn't take of yet? Everywhere else there is a strong open source alternative where there is a dangerous monopoly: With operating systems, there is Linux, with browsers there is Firefox, with graphic editors there is Gimp(shop) and so on and so forth...

Nutch, Grub and so on are no real alternatives yet..

Yeah as Tadeusz Szewczyk said:"We need open source search Engine" "Open Source AdMarket".so that whatever earned by AdMarket can be dedicated to Open Source Projects.

Actually the secret is know. There is a whole bunch of competing monkeys fiddling with the rank engines day in and day out! Code monkeys?

Dannie, I think you missed something, it's pigeons. ;)

I think Haohi nailed it :D

The problem with an Open Source engine is not the source as much as the CPU – that is, the server-power required to run everything for a service would have to be donated. Linux, Firefox, Gimp, etc are all run *locally*.

Thanks, Philipp! Real fun to read.

Very funny! It is like coca cola secret formula. If you kwnow Google must kill you!

Maybe that open source search engine would need to be distributed among many different computers. A small program that, when the PC is idle, computes queries in the background. A bonus would be that you couldn't censor this easily, because it's not controlled by a single source.

Just finished translating the script, here it is, play with it if you like.
http://googlified.com/junks/check.phps

global PgRank;
if { [catch foundPage] msg } {
   foreach word (getKeyPhrase()){
   if { [regexp -nocase $word "Don't be evil"] && getTitle(url)!="Google" } {
   PgRank=0;
   } else {
   PgRank++;
   }
   } else {
   response.redirect("http://www.google.com/ig");
   }

Haochi:
> $pagerank += countBacklinks($url) / 10000; Help me with this!

Can't you just screenscrape the page count from a Google search on [link:thisdomain.com]?

I thought it would be easier to do it with Google Search API, but I have no experience with the API.

It would be very, very, difficult to have a distributed database and computation engine. In fact, that's what Google does, and it's why they're building huge server farms near hydroelectric power plants.

awesome!!

// added for fun
if ($TitleOfPage($url) == $search && $internalPageRank<rand(0,10)) {
setHiddenPagerank =-100;
echo "Did you mean: ".opposite($search)."?";
}
