Have a good navigational link structure and link to inner pages naturally in your content.

 

what about out going links ? ..like guest posts ? how many should i allow to do it ?

 

There is no limit on the number of backlinks you should get. The more you promote your site, the more traffic you can expect to get.

 

No i mean another blogger wants to submit a relevant guest post on my website and i want to make 1 or 2 dofollow link to his blog ..dose it reduce my ranking on google ?

 

No just make sure you don't link to bad neighbourhoods.

It is a silly question, because guest bloggers are only interested in submitting a post if you offer them dofollow links.

 

i know that is why i ask it ..i want to be sure it will not effect decrease ranking as i am not sure how to do it .

 

if you want to set outbound link do no set in more then one word and set always no-follow link.

 

The best way is to build hyperlings throughout your content that links back to the inner pages you want.

 

You Choose It By Yourself ! If Your External Links Have a High DA or PA And You Use It In The True Place In Will Increase Your Seo And Your Ranking And If Not It Decrease Your Seo And Your Ranking

There is Many Plugins To make Hyperlinks But Machines can Do wrong And It Will Be Better If You Do It Manually

You have to know that if all words of your page or post affected by Links ( Doesn't matter Internal or external ) It will be detect as a spam page

You Can Set 8~12 External And 6~8 Internal Links

Do Not Set Rel or Title For Your External Links And For Internal Links Just DoFollow

It's Better If You Link Your Keywords For Internals !
