Thanks for all your valuable intput and suggestions. I've also learned that its good to get new high quality relevant links point to your internal pages. I've also read from good
SEO tutorials that these are why a website ranks high:
40% because of old BL(backlinks)
25% because of new BLs
15% because of updates
10% because it offers a useful service or resource
10% (other
SEO work like check broken links, ensure site fast loading etc)
