is there a penalty for linking from multiple pages from one domain?

is it an acceptable tactic?

[tim3562]

say you do a link exchange with a guy that has 20 pages or so indexed in google, under the same domain.
if he links your site on every page, would you get penalized?

[mil2k]

If there are one way links then at present there is nothing against it. Since you say it is reciprocal you may want to read the "Second Eigenvalue of google matrix" technical paper. They show you exactly how they detect cross-linking. HTH

We have a large site, and I have 3 more in the works. Three all related to our industry, providing slightly different services and one support site to cover all. On the main site at the moment, I have a put a footer with links to all 4. I had planned on putting the same footer on all 4 sites. Is this not advisable then?

[mil2k]

No that is not the point! Linking from the home page to your other four sites is ok but linking from all the pages of the four sites of yours to all the internal pages of all the four sites may not be ok.

[NexDog]

So to clarify, linking to the index page ONLY of all 4 sites from every page of all 4 sites is ok? So if every site had a 1000 pages, each site would have 4000 links pointing to its index page.....ok?

[mil2k]

No it is a bit more complicated than this. Let us say you have site A,B,C. Each have 25 pages. So you link from A to B & C . From B to A & C and from C to A & B. This is OK. Now you link A1 to A25 to B1 & C1. Do the same with other 2 sites. This may not be ok because you may get a cross linking penalty. There is a way out of this but that is a different topic.

sorry for this question, but I have realy the problem not to understand the definition of bad reciprocal linking... I am very confused.

what ist the structural difference of internal back linking and bad reciprocal linking?

let say, I have a site with the following hierachical structure:

- homepage
- some categories
- articles under categories

with:
- backlinks from article pages to each categorie and to the homepage
- while homepage is linking each categorie
- and categorie pages are linking to articels, linking each categorie and linking back to homepages

to do this all internal in one domain is reciprocal linking but a usual navigation structure?

to do this over different domains is reciprocal linking and a bad SEO technique?

I used to do the exact same thing, I had 100 pages with a link on each one pointing to one page on a different site.

Never hurt me, I took it off after a year because I thought that it looked abit naff.

I have seen it many times when a designer links every page/site that they have ever done back to their own site, it doesnt do any damage but it looks a little unprofessional.

[h_b_k]

my structure is a result of checking log files for sessions resulting from SERPs: the better my SERPs positions, the more one-page-and-run-away-sessions I got.

before I had only back links to the homepage and to the category the articels belongs to.

giving each article page a navigation bar to each categorie must be a big service for users: the amount of sessions with more then one page visited has increased.

[creative craig]

What I explained wasnt reciprocal linking though, it was one way linking.

So the Second Eigenvalue of google matrix doesnt relate as it isnt heavy cross linking, no crosslinking at all.

[mil2k]

That was not for you creative craig. The thread question was about link exchange and that is what i was trying to explain. :-)

[WebGuerrilla]

Cross linking from a common footer isn't a problem as long as the individual sites also have independent inbound links. It's only when your entire PR comes from your own network that you will run into problems.

[Krapulator]

From Second Eigenvalue of google matrix:
"These leaf nodes in the SCC are those subgraphs in the web link graph which may have
incoming edges, but have no edges to other components. Link spammers often generate
such structures in attempts to hoard rank. Analysis of the nonprincipal eigenvectors of
"A" may lead to strategies for combating link spam."

Its all so much clearer now! Thanks Mil2K ;)

[mil2k]

Cross linking from a common footer isn't a problem as long as the individual sites also have independent inbound links. It's only when your entire PR comes from your own network that you will run into problems.

Yes that's the most important factor!. Always to be remembered.

[h_b_k]

oh yes, I remember this thread. and the most important information for me was: "Essentially a web graph is "site" blind -- it does not see the difference between one domain and another."

and I remember the question about "model train sites" and a closed loop.

the conclusion is to link to sites which won't link back to you and hope, there will at least one model train friend with a very other interest.

but: isn't the whole web a big circle? ;-)
