It is no secret that link building is critical to SEO success. However, some people often ignore internal links because they are just not aware of their SEO benefits. To most do-it-yourselfers (DiY), link building for SEO means external or inbound or backlinks. These are links that originate from another site and point to a page on your domain.
Don’t underestimate the SEO power of internal linking. They are not only great for increasing the number of pages indexed by Google but also help you target a larger number of keywords, especially long tail keywords. The number of site pages indexed by Google has a direct impact on your online lead generation. For every 50 to 100 pages indexed by Google, expect double-digit growth in the number of leads.

The best news is that building internal links is completely in your control.
