Sometimes adding the exact keyword may not grammatically make sense and LSI keywords help you to overcome such issues. Google is wise enough to understand the relationship between synonyms and related phrases.

LSI Keywords are synonyms of Primary Keywords. Google can understand your content through LSI keywords and by using LSI keywords you can target other synonyms that give the same meaning as Primary Keyword.

From this example, you can see that both the keywords mean the same but they are just synonyms of each other

No-follow backlinks are the links pointing from one website to another but they do not help in the transfer of any authority to the linking website.

Websites having deep site structures such as e-commerce websites use breadcrumbs to tell the users where they are and breadcrumbs make navigation easy. But breadcrumbs are not necessary for small websites.
