I don't want to take away anything from you - just enjoy and live the moment. But these days - mere sitelinks does not measure to authority status ( Once, I have been one of the strongest supporter of it). I have few examples of even penalized sites for more than a year having got those sitelinks (I know since I always monitor this sitelinks factor). But yes - if you have got those extra links - it means your site has been built according to Google's guidelines and if there is no penalty on your site - you will get tremendous SERP boost with immediate effect on all your keywords/phrases. I have couple of sites with sitelinks too. These days real authority sites are those - which show SEARCH option on Google result alongwith sitelinks. Think of a site you think should be of highest authority - & you will get that SEARCH option. (not even digg/facebbok are authority sites, but certainly NASA/FDA/HARVARD are) Here is an example of what I am talking about a REAL AUTHORITY SITE
I had it and now I don't...why? Because it's completely automated and doesn't mean what it used to on Google. I was excited too, until I found out it was becoming more wide spread. It will come and go....but enjoy it for now.
Hello! Your competitor is just 250K; plus, PR is different from SERP. Having high or low PR doesn't mean you'll have a high or low SERP.
Great work man, I'm sure you put a lot of work into it. Hopefully before too long my work will pay off too. I'm sure it must be a great feeling.
