The links from your website to other sites can also influence the positions of your pages in Google's search results.
Links to other sites add value to your website; they show your visitors that you have nothing to hide and that you have confidence in your website.
If you offer your website visitors links to other sites, you can send leaving visitors to other websites that can send you their visitors in return.

Even you don't visit your own website all the time.
Give, and you shall receive
This is true for many aspects of life and it also applies to website promotion and link building.

High-quality links

 20 good links are better than 100 low-quality links.

It's good if the link is from an authority site

In the worst case, low-quality links will have a negative influence on the rankings of your pages.

 factors that define a low-quality link

The link is from an automated linking scheme

Automated linking schemes usually promise hundreds of links in a very short time with very little work.
All major search engines have employees who actively seek for these linking schemes. Use common sense: If you can find the automated system, search engines can also find it.

 The link doesn't go directly to your website

The link cannot be parsed by search engine spiders

 If the link to your website is hidden with a scripting language, search engine spiders won't parse it.

Co-citation and bad link pages

The search engines look at the link pages and check to which other websites the pages link.
Co-citation and good link pages
 If you're listed in the "Shoes" category of a link directory, all websites in the same category are usually also about shoes.
What does this mean to your link campaigns?
It's not necessary that the other web site is completely about your topic.

How to judge the quality of a linking page

Do not focus on Google PageRank or similar metrics
