How long until links 'fall off'?
-
If I have site A linking to site B, and take down the links - does anyone have any experience in about how long they take to 'fall off', that is stop appearing in Webmaster Tools or Moz? I'm going on three weeks currently. Perhaps this takes months?

The next time Google crawls the previously-linking page, it should note that the link is gone, as it will cache the page. Any benefit or detriment that the links was passing on should technically be nullified. Moz's crawl will update when it re-visits the page as well, but the frequency of Moz, Googlebot and the updating WMT is really hard to predict. If the link is on a highly-traffic, well linked-to page, G and Moz should pick it up quickly. If not, it can take a long time.
The Moz index is updated about every 3 - 4 weeks; again, the removal of one individual link requires the latest crawl to have noticed that it has gone, which is likely but not a certainty.

WMT can take a long time for anything to update.
but the search engines would have that change by now in there index

Should we use 'disavow' if we dramatically dropped serps after Oct 5th, but did not receive a warning?
We dramatically dropped serps after Oct 5th, but did not receive a warning about bad links on google webmasters. Is it a good idea to find and collect the worst links and disavow them? As there was no warning we can only guess links were the problem, but it seems likely. However we do not want to send any requests to google if no warning was sent. Can disavow be used in this way, or should we do more manually? (We are hoping remove links + increase very solid links + optimize for key words will help revive serps) Many thanks. James

Penguin Recover: Remove links vs Burry Links
The best is to do both. However with those with limited resources, would building more links with branded and naked URL anchor links be a better solution than painstakingly asking every webmaster to remove links.

How might Google differentiate between an artificial link exchange and partners linking to each other?
Hi, All! Artificial link exchanges (contacting a vaguely connected site and requesting to exchange links to increase your PR) is, as far as I know, considered an outdated, not-so-smart technique, as Google might devalue them. Yet, for real business partners to exchange links seems to be an entirely accepted and encouraged technique. While that would be intuitive to a human who's viewing the pages. how might Google detect when two sites that link to each other are linking because they are trusted business associates (valuable) as opposed to when they are doing a link exchange (devalued)? Thanks! Aviva

Whats with these links
I have a competitor
Link Building | | AlanMosley
that has shot up lately taking number one spot for various keywords when I look
at his links in Open Site Explorer I find many links that are links to downloadable
objects, not web pages. A few
examples, if you click on them, do not open who knows what they are. But what
the story, how are these links to his site, anyone know anything about this.

Do image links with no alt tags pass link value?
"... an image link with no alt tag is useless to search engines..." according to a Nov 2007 seomoz blog post. Is this still the case in 2011? I ask because I'm about to obtain a banner link on a high-traffic site (chiefly for the clickthrough value) but I notice the site uses neither "title" nor "alt" tags.
