Unless you have no clue about what is going on and think GooglePlus counts are the number one ranking factor, you’ll realise building high quality links to your site is STILL the single most important thing you can be doing to improve the rank of an already relevant page (if you haven’t been doing anything shady in the past, that is. If you have, you need to concentrate on dissociating your self first from unnatural links).
In competitive verticals – you can easily follow Bing/Yahoo clear link building guidelines to rank in Google, but forget to try and rank in Bing/Yahoo with this same technique because to do so, you need to use Google Webmaster Guidelines as a rulebook for success, and that will penalise you in, em, Google, which no sensible person wants.
Bing and Yahoo encourage you to outreach for relevant links to improve the rank of your website:
“simply ask websites for them”
“Correspond with webmasters of related sites and other providers of relevant content in order to increase the number of links to your site.”
Google has a different view.
“Any links intended to manipulate ….a site’s ranking in Google search results may be considered part of a link scheme and a violation of Google’s Webmaster Guidelines. Additionally, creating links that weren’t editorially placed or vouched for by the site’s owner on a page, otherwise known as unnatural links, can be considered a violation of our guidelines.
Basically two of the 3 major (UK) search engines encourage you to ask websites for links to specifically improve the ranking of your site, and the biggest, Google, tells you not to do it at all. Bing’s SERPS (which go a way to power Yahoo searches) look pre penguin and pre-emd Google serps.
You can easily rank in Bing and tank in Google, these days.
Actionable Advice From Yahoo and Bing:
Get links from related sites. Ask for links to increase the number of links to your site. (quotes)

If we spot a linkbuilding footprint we will f*** you. (paraphrased)
