Does having more than one backlink on same page to your website decreases the link value? For example if i have 2 backlinks on same page that point to my website? Does page rank juice gets divided between these two backlinklinks that point to my website? Is it better to have only one backlink?
Yes; as long as it's the "same web page" and the best solution is to link to two separate web pages on your website. You should be building links to your internal web pages anyways; as it appears to show as natural link building. Also avoid using the same anchor text with multiple links.
Matt cuts lately clearly explained this concept. there is no harm in getting 2 links in the same page.
I'd sure love to see a reference to this; how multiple on-page links to the same URL don't get keyword dilution.
there is no harm, except to your rankings Google only count the first link to any page from any page. http://www.seo-scientist.com/first-link-counted-rebunked.html
there's no problem with it, you can do this by designing your article or blog entry to encourage readers to visit that link, but take note that the second link has no value at all and it won't pass link juice.
