SEO consists mostly of onpage and offpage optimization. Onpage can mean a lot of different work tasks: content optimization, anchor tags, alt tags, keyword density, you name it. When talking about offpage, the big player is definitely linkbuilding! Linkbuilding can help a website a lot more in ranking than just onpage work. But, a link can give you a lot of “link juice” (increase in trust that Google puts in a site), or even hurt your page if it comes from a spammy website.

The quality of a link depends on several factors:

Strength of the link

The qualitiy of the site the link comes from

How relevant the site is compared to yours
