I bought a old domain, but it has directory links all over it...The website i built is a (classified) is this going to hurt my website?
I would recommend you work in the same way as for old domain name used to. I suppose that in such way you will make things much more better and that domain name will have double efforts.
What is the niche of site that hosted in the old domain? If the site is classfied,then the directory link will not hurt your site but In fact it will help you in gaining traffic.
The sites showing a bunch of good links, but who ever owned the site delt with alot of spams sites as well, but i found out that this domain rankland.com is about 5yrs old with 26000 links at google when you use rankland as a key word.....
