Some people will argue with me here the single most important factor is the incoming links. There are a few types of different incoming links. I personally have had 3 websites rank on number 1 for google.

a)--One way links: One way links are just that. You have a website giving you a one way link to your website. These are valued the highest of all the links coming in. How would you go about getting these types of links? There are websites out there that offer that. Go to google and type in "one way links" You'll get plenty of results. It never hurts to do a little research on the sites before accepting their terms.

b)--Reciprical links: These are links that would exchange with someone, and the most common type of link. How would you go about getting these? Simple, you just ask. Send them an email with your name your website, telling them you want to link. Put the link on your site first, and let the webmaster know where it is. If they don't respond contact again in a week. Still no response, delete the link.

c)--3 Way Links: They are 3 different websites all 1 way linking to each other. For example: Site A,B,C... Site A Links to B Site B Links to C Site C links to A. If this is confusing, draw it out on a piece of paper in a triangle shape, and you will see A--B B--C C--A.

Another important thing to remember is to link to websites that have the same theme as yours. Incoming links can't hurt you, but your out going links can. If you have a website about dogs, you don't want links coming in from Debt Companies, get it?

Of course there are a few other things that contribute to getting a high ranking page, but I'll go over that at a different time.
