Hello I want to create a new web site, I have to choose between:

1/ using one of my former domain name that dates  about 10 years ago, which has a lot of backlink (PageRank 4) but without the anchor text of the new area of activity that I want to launch ...

2/or purchase a new domain name with two keywords which I want to be positioned in the first place: P Which method is better for good and quickly results ?

Thank you for your help

Looking forward, if you plan on keeping your old domain well into the future, search engines do take into account the domain expiration date. This indicates to search engines how permanent the site is, but I can't say how much this will affect your ranking.

Choose the domain that will give you the most mental energy to work on the site.

That is worth waaaay more than backlinks!

A very common myth exists related to the age of the domain.  If the new site is going to have different content, the age of the domain is not going to be helpful in the long run.  If you have any content on the old domain that you can use on the new site, you can make use of that value.  How much value you get and then keep over time depends on how much of the content you can keep, and how many of the links pointing to that content you can retain.

The further away from the older domain's topical focus you go, the less value it has as well.
