PR value of reciprocal vs One-way links, related vs not

[jacksdad]

sorry if this has been answered 100 times, but I did a search and the terms are too generic... I gave up after reading a dozen posts. Anyway, does anyone know the following.
Lets say I have a home page with a PR4, and I find another website's page with a PR5. Lets assume I'm the only link on it.
How much does a one-way link back to me count (85% of 5?). How much does the link count if I have a reciprocal link to the site (a lot less? is it worth it). Do multiple links on a page simply divide the transfered PR by the same amount.
And finally, how much does a non-related reciprocal link count versus a related link? not at all?
I'm asking all this because I'm wondering how many quality related reciprocal links I need to get to have any effect on my PR ranking, and if its worth it. Do I need 100 recip. links to equal a 1-way. If so, I put my effort into the 1-ways. Appreciate any answers (Google, are you listening?) or if anyone points me in the right direction. THANKS!

depends on where they have the dampening factor set. please note that internal links also count in the link total and the scale is logarithmic.

while reciprocal links are likely discounted some, I have done very well for a few customers by getting a powerful inbound reciprocal link or two.

link popularity is split up amongst all links on the page.

as to whether reciprocating links is worth it, that should be evaluated on a link by link and site by site basis.

non related links are still weighed in rather heavily. they count as much or near as much as related links (currently in google).

assuming all other things are equal the ratio would be way way way way less than 100 to 1. often times great resources cross reference each other. by extremely penalizing reciprocal linking the search engines would make the web become more fragmented. if search engine watch featured me in his website then suddenly it would discount my sites value to link back to his? search engines want to promote healthy linking. some reciprocal links just happen naturally. while they may be deweighted some the 100 / 1 ratio is way off.

also, pagerank isnt everything. rankings are what is important and good anchor text is just as important or more important than pagerank

Best thing to do it make sure there themed and atleast try to get mostly one way inbounds....

I think you are looking to quantify something that is beyond human quantification.

Non-reciprocal links are better, all other things being equal. Since not all things are always equal, you probably want a healthy mix of reciprocal links and non-reciprocal links.

Personally, I find it takes more time and energy to get reciprocal links of any quality, so I focus on non-reciprocal links, since they are better anyway...all other things being equal.

awall19 et al...
thanks for the detailed answer. I figured everyone would be speculating based on their own experience. Only the google programmers know for sure (if they do) and they'd be shot if they talked.
Sounds like at this time reciprocal links are almost as good, at least 50% as good, as 1 ways. I guess non-themed count too for now, though the danger is that google could change everything at any moment.
appreciate all the input.

best of luck jacksdad

amabaie please limit your sig links to two

I stayed up late last night (paid the price this morning due to our newborn) researching backlinks and PR. Here's my thoughts:
I'm not sure google is applying any penalty to backlinks...
Assuming transfer PR value of a 1-way link is the page PR x 85% / # of links

They could filter as follows:
1) if it is a backlink, reduce value by x% (i.e. 50%)
2) check if the links are related. Do any of the top 10 (based on density) keywords in Site A match those in Site B. If not, reduce value by y%
3) check if the link is "spammy". Do any of the top keywords on the site match their spam word list. If so, reduce value by z% (lets say 95%).

Seems like filter 1 would penalize the entire net, including google.
Filters 2 and 3 would penalize automated linking systems and link farms.

does anyone have any evidence that any of these filters are in place, or any thoughts? My guess is that 2 and 3 are here or near, so I plan to stick with related links only.

Must fight that temptation to copy my high ranking competitors...
Hope to get some sleep tonight...

My guess is that 2 and 3 are here or near, so I plan to stick with related links only.

Some devaluations that can easily be applied (here or near, perhaps?):

Devalue additional links from a single domain, so that intenral links would count less. That would make it less profitable to generate 40,000 page sites through databases for internal links, and less worthwhile to buy links in forums or to spam forums.

Devalue links to domains that also have links back to the linking domain, making it less profitable to create reciprocal linking for the sole purpose of manipulating the search engine rankings. (OK, so this one is not that easy, but it is doable).

if filter #1 penalized the whole web then there would be no net penalty as it would cover the whole web fairly comprehensively (except the sites that bought link popularity and did not link out to other sites)
to offset something like that they would need to penalize sites that lacked outbound links.

filter 2 would be hard to apply the way you are stating since the page the link is on may not match the theme of the site and it would be hard to determine the theme of each and every page on the site quickly just to evaluate 1 link

filter 3 may work, but the spam penalty would be better matched against other things than just a keyword.

i would love to go to school to learn how to better structure unstructured data.
