Www.domain.com Against Domain.com

[Airness]

My website have a pagerank on DOMAIN.COM and DOMAIN.COM/index.php. However, I do not have a pagerank on WWW.DOMAIN.COM and WWW.DOMAIN.COM/index.php. Is this normal? Please advise.

[Andy AtkinsKruger]

That's normal - but not healthy! Google's BigDaddy aims to sort out all these kind of issues - but basically - for your sake - you need to make one domain and one home page your substantive - and redirect everything else using 301 to that.

So choose www.domain.com or domain.com - and 301 the other to it.

Point everything to one home page - eg www.domain.com/ - and you'll probably see things improve.

This ultimately might be fixed - but for now best to play safe this way!

cheers!

I want to choose domain.com, because it has a pagerank. If I redirect the www (no pagerank) to domain.com (with pagerank). Will I loss my pagerank?

[Andy AtkinsKruger]

The first thing is that you shouldn't worry to much about page rank - as it isn't a great indicator.

In deciding, I'd have a look at what Google has in it's index - (use the site:domain.com) and make a judgement as to which one Google prefers from you domains. Look at what's in the cache for each domain - how many pages from each domain and make your judgement from that.

It may coincide with the page rank information you have - but not necessarily.

PR and the number of pages indexed are something to look and may have a lot to do with making the best choice. I would also suggest checking backlinks at Yahoo for each, and see how they compare. In the long run the BLs might be the most important factor, especially if you have a lot them.

does anybody know when the estimate time of completion of big daddy google project?

[JohnW]

a little off topic...but BD is a work in progress over the next several weeks.

I redirect a index.html (with pagerank) to index.php (no pagerank) before. To be able to transfer the pagerank of index.html to index.php.

I'm worried to lose my pagerank, when I redirect the www (no pagerank) to non www (with pagerank). I checked Google. Google prefer my non www to index.

[JohnW]

I don't know about redirecting .html to .php but I think what Andy AtkinsKruger means is to set your internal home page links to point to the homepage folder, not to the file name. This is the correct way to do it.

in other words you should never have a link to domain.com/index.html or to domain.com/index.x

It should always be pointed to as domain.com/

[Airness]

I use domain.com/. So, I'm on the right track. yes yes yes

[stgma]

and what happens if half your backlinks point to www.domain.com and the other half point to domain.com? does the 'power' of the backlinks get 'halfed'?

thanks

[JohnW]

>does the 'power' of the backlinks get 'halfed'?

Yes that is how it works currently. Also, if these pages both are indexed and both have a good link count, one or more of them may get killed because they are duplicates.

[Andy AtkinsKruger]

stgma, that set up with backlinks pointing at two different so-called canonicals (www.domain.com and domain.com) is going to cause you problems.

You need to 301 one of them to the other - this would then transfer the backlinks value of one across to the other.

You will then lose a much smaller percentage of their value to you - ie less than half!

[Andy AtkinsKruger]

Airness,

Matt Cutts at SES New York said it would be 5 - 6 weeks to completion of big daddy - that's somewhere in mid-April.

The reason for the timespan is transfering the new infrastructure across all data-centres.
