Hello, I have been optimizing a website since 2 years.No doubt the site has good page rank and couple of backlinks too.Now you might be wondering that now what else my problem would be. Actually my client always wanted me to do lots and lots of links submissions parallel to article submission,blogging,forum postings,Blog commenting,Boookmarking,Link exchange and all. But now i really find difficulty in searching new link directories and that too on regular basis.I have informed this thing to my client, still he wants me to do the same. Yesterday also while we had a meeting he mentioned to put more focus on link submissions.NOW i am totally messed up and confused that what should i do?????? PLZ HELP ME OUT IF YOU HAVE ANY GOOD SUGESTIONS & PLZ PLZ DONT SPAM WITH YOUR SILLY ANSWERS.
I can understand your situation but there is no limit of doing off page activity. Take link building as an example, in this case you can wary your keyword range in such a way that gives you the different data. Also you can choose different search engine for getting the sites.
Use other methods: press-releases, CMM, CMO, link services (like in the signature), viral marketing, and you will get new sources. There are unlimited possibilities in the net nowadays.
