Google updates its search algorithm frequently. For example, on February 23rd, 2016, Google made significant changes to AdWords, removing right-column ads entirely and rolling out 4-ad top blocks on many commercial searches. While this was a paid search update, it had significant implications for CTR for both paid and organic results, especially on competitive keywords.
As keywords are essentially the backbone of on-page SEO, you need to pay a lot of attention to them. There is no reason not to include them in your URLs. The inclusion has its benefits. When you assimilate the targeted keyword into the URL, you are ensuring that Google’s has another reason and way to consider your article as more relevant for a particular phrase.
2. It could be easier to get a backlink with a jumplink especially to your long article/page, as it is easier to create/add linkable content to your current long page. Instead of creating a totally new page. And for the site who would link to you it would be more relevant if the link goes directly to the part of the page where they are referring to in the backlink.
This is not to say that small businesses can’t show within the top organic results. If your business is located in a less competitive market or industry, like a nail salon in a small town, you have a better chance of ranking high in organic results. Most small businesses find it easiest to rank within local results, though small businesses can also rank high in organic results by investing in search engine optimization efforts.
