if I added a bounc of backlinks to my website, ( they are usualy on index.html pages so google/yahoo/msn allready crawled them and known about them) How fast I will see results in serps?! I think that MSN is updating results made because of the changes of backlinks every weekend?! When Google/Yahoo is updating results made because of the changes in the number of backlinks a website have?!
It depends on how frequently the site (& specifically the page) that is linking to your site is crawled!
I don't think that is true. Google constantly updates backlinks but only updates what we can see every 2-3 months.
Yes it is pretty obvious that they update backlinks in their databases all the time, otherwise it would take 2-3 months (until the next update) for a new page to be crawled
Yes it is updated constantly but we can se those backlinks in link search approximately every 2-3 months.
