I have a website whose name coincides with another popular domain. Meaning if you add two letters at the end of my website name, you get the name of already popular domain. After registering and getting my website running for couple of months i realized it as when I used to type my site name in google, the auto-suggestion tool completed my query with that particular popular domain. Since the site was running and known to few people, I thought regular updation of content will solve this issue. But, still after 6 months, google auto-suggests that name. So, my basic concern is whether the name chosen is very bad for SEO and brandability? Will I be always over-shadowed by the older, popular domain?Just brief me how to go about this as I want the sitelinks and auto-suggestion to work for me and not against me
