The Senior Product Manager of Bing, Duane Forrester, wrote a post on the official Bing Search blog throwing light on the ten myths in SEO, in which he makes a revealing point about links- You should never know in advance a link is coming, or where it’s coming from. If you do, that’s the wrong path.
You should neither buy links, nor ask other webmasters to link to you. In fact, you should avoid doing any action at all that you know will lead to you getting a link from a source.
Forrester says that there is so much link spam these days that it is difficult to decide where to turn to. He says that buying links is a dead end, and sharing, encouraging, incentivizing or buying them is all the same. In Forrester's own words, “Links are part of the bigger picture. You want them, but you want them to be natural. If an engine sees you growing them naturally, you’re rewarded with rankings. If they see you growing them unnaturally, you’re rewarded with penalties.”
Apart from this, Duane also talks about some other myths revealing that often the click through rate of the page 2 results are way better than those on the lower positions on page one. So if you have a good ranking on page 2, think again before planning a tactic to move to page one. Duane says that gone are those days when ranking a website was like preparing consommé. At that time, you could boost your rankings by focusing on a single tactic. But this is not the case today. You cannot improve your rankings just by focusing on a single strategy. For example, although the title tag is very important, a well-crafted title tag alone cannot save a website that skips on everything else. Similarly, social alone cannot improve your rankings. Again, although videos are easy to produce and consume, embedding videos can lead to longer page load times, thereby annoying the visitors, plus a video alone cannot help improve rankings.Bing Says No to Link Buying, Recommends Building Links Naturally!,
