Ranking on the first page

Here is an interesting question I came across;

When I searched for the keyword “vinyl windows rochester ny”, I found one interesting organic results on the 1st page of Google for “Cameron Windows and Doors” business (4th position). I was shocked to see this website on #4 position. When I go through the website, it is having very less number of pages on the website and its PA, DA, backlinks counts, Referring domains are comparatively less than other competitors who are ranking on the first page.

So, I just looked into the on-page, I found everything well optimized there, but not sure what extra things they have put into the on-page to rank the website so well. After digging into the depth, I thought it could be the breadcrumb, which is helping the website to get rank higher, so I applied the same on my website, but still, my website is on the bottom of the 1st page. I want you all to please look into the website and suggest me some points that I can implement too. Other competitor`s websites are very big and famous brands, so beating them could take time, but i would appreciate if you could go through the all top four results and let me know your expert views.

Thanks in advance.
