What the white hat people are saying to you use, " get links". You see they are just fluffing it up in jargon and misinformation so they in return can get links. The reason they want links is because the number one ranking factor in all search engines is........ Yes you guessed it links. Lets take a look at my paint skills er I mean diagram.
What you see above is a straight up paint master piece. But it pretty much sums up everything white hat. At first glance you might think your prodigy 6 year old might have drawn it but I assure you its all me.
Lets dive in an put some shit to bed.
Fresh Content
The idea of fresh content is a small ranking factor but the reason you want to do it is for links. You see the more more posts you make the more chances one of your epic, mind blowing master piece might be read by a linker(ie reader). Then the linker does what any good linker does and posts something on there mommy blog about your post and then you receive the all might link.
So from the diagram we can see the site on the left only has a few posts so naturally they receive less traffic from natural linkers and they receive less natural links. Site B has alot to say and they posts lots of useful content about random crap and more linkers have a chance to grace there blog because they have more posts. So naturally they get more organic links.
Social Signals
Social signals are guess what?
LINKS!!!! So when your epic master piece gets passed around like a joint at a Grateful Dead concert you gain more links. So as you can see the site on the left only has a few posts so unless there posts are incredibly link baity they well attract less linkers to there sight and in return get less links. Site on the right has more posts so they have more linkers visiting there pearl of wisdom and get more natural links.
Black Hat
Black hats say f the graph Ill blast my oh shit to kingdom come and back again. So they cut out all that wasted time on posting fluff articles to the linkers because they dont need them. Sure ,they like them but why waste time writing fluff pieces??? Cut out the middle man and blast away is there moto...
Content is King??? WTF LOL
Content is only good for two things: links and sales. So if your wanting natural links you better write your ass off, if you want linkers to do there job. So i guess that really makes links king huh??
TO sum it up
Im not proof reading this, your lucky I made a diagram. Also, links are king. Everything you do is to get a link in some form or fashion.
