Having large groups of content that all revolve around the same topic will build more relevance around keywords that you're trying to rank for within these topics, and it makes it much easier for Google to associate your content with specific topics. Not only that, but it makes it much easier to interlink between your content, pushing more internal links through your website.

Some companies have successfully sued to have their pages removed from these frames because it can make some readers believe that the linked page is actually a part of the originating site, and possibly owned or authored by that same site.

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.
Organic search results are free and display below Google Ads and sometimes local results. Google uses a sophisticated algorithm to determine which sites rank highest for organic search results based on keyword usage, relevance, site design, and other factors.
