I don't think so . I have seen many blogs with site link and many received site links on this update too but they are not able to beat olders till yet .
Anything is possible but sitelinks suggest that google considers the site an authority for that keyword, so you have a lot of hard work ahead of you to get the number 1 spot.
Haven't seen any sitelinked blogs myself. Would you mind dropping a google search page to have a look?
It will take good amount of quality links, time (age), and resources to beat a site with sitelinks and get #1 spot. I'd suggest you to double check whether it's worth the efforts or not.
Yeah! it definitely depends upon competency of keywords & search results! If your site is unique among Search Engines then you easily rate it best with no time but if competition looks harder among results then it requires ages to attain desirable position
I don't think I've ever seen a site with sitelinks that isn't ranked 1-3 on the first page of results. You would have to be a very established and focused on the search terms website to beat a website with sitelinks in place. That is my dream to get sitelinks to my site. It makes you feel so important, like your website has "made it".
So basically, we are talking about spending weeks if not months on development in order to reach the highest of the high?
