hi people!...

Since a few time ago, I'm seeing no links when I search google for link:www.sitename.com . It only show internal site links, not external...
The links are here if I search link: www.sitename.com (with a space between link: and sitename) and they are PR0,1,2,3,6 etc...

Somebody see something like this ?...

Putting a space after link: performs a completely different search. You're basically saying find me pages that contain either the term link: or the term www.sitename.com.

Google never shows all the links it knows about. They only show a small sample. It's better to check for backlinks at Yahoo since you'll get a more realistic count.

Yes, I know that!.. But from time to time, the links are showed, and later does not!!... I had approximate 40 external links in these results, and now 0 !...
Very strange, I think...

regards,

Google recently updated what they show in backlink searches. I've had my own count go down after some updates even though I gained backlinks in the time since the previous update. I don't think it's all that uncommon to see less backlinks in Google than you had previously.

If it's going up and down you might be hitting different datacenters while they complete an update.

You should be worrying about what you have, not what google say you have.
The google link: operator is about as reliable as, well, a really unreliable thing.

have you really read my post ?... you should do it first...

I saw if somebody see something like this, not if I worry about this, nor it is or not a unreliable thing

If someone see what? Googles link operator being worthless? yeah, I've seen it.

If you see different results at different times it's more than likely for one of two reasons. Either google have had a data export or you are querying different datacenters.

For google, that's true, with or without the space between : and w will have big difference in number of backlinks. If you want to know how many backlinks you have, you'd better trust yahoo. Google never shows the exact numbers, and only its datacent knows how many backlinks you have.
