Any inbound link is a good one, but there is a wide difference in their quality. One link from a respected, popular website may be worth more than ten links from low-ranking or poor quality sites.
Reciprocal Links: friends and associates
Trade links with business associates and anyone else you know with a website. Contact fellow members of associations, your chamber of commerce, social organizations, or any group you’re part of. Place links to each others’ sites since you already know and trust them. Maybe you’ll be allowed a longer description or preferred page placement because of your relationship.
