I am wondering how the relatively new sitelinks search box impacts the SEO rankings for a specific site or keyword combination - do you guys have any experience or bechmarks on this? Obviously it should help on getting more real estate on the SERP page (due to adding the search box), but do you also get extra goodwill and improved SERP position from adding it? Also, is the impact different on different type of terms, let's say single brand or category term such as "Bestbuy" (or "coupon") or a combination term "Bestbuy Apple" (or "Dixons coupon")? Thanks in advance!
