In my opinion it is not rocket science. As long as you have a well designed and optimised website the most important thing you need is backward links and lots of them. These links should have different link texts which even though different will always include your keyword. For example if the keyword is stuttering the link text could be, stuttering therapy, stuttering information, stuttering treatment, stuttering help or stuttering advice.
There are two types of backward link, reciprocal and non reciprocal (one way links). A lot of people make the fatal error of obtaining many reciprocal links but hardly any or even none, one way links. This is not a good idea and you may even be penalised by the search engines for this.
Reciprocal links
It is very natural for a website to have many reciprocal links as long as they also have lots of one way links. To obtain any link can be difficult and time consuming and I personally recommend a program like linkmetro to help you to obtain these links.
One way links
Where possible it is of far greater benefit to obtain a one way link. Some people choose to purchase a link on a high ranking page of a website as it can be difficult to persuade a webmaster to include your link for no reason or benefit to them. If you have more than one website you could however offer them a three way link exchange.
For me the best way of obtaining one way links is by writing articles like the one you are reading. People are able to use these articles on their websites thus creating a one way link. You also obtain a link from the websites you submit the article to such as:
