One important component of your SEO strategy is link building. There are two types of links that are important for SEO - outbound and inbound. Outbound links are links on your site that lead to an external page, while inbound links come from an external website to yours. Inbound links are important because search engines view them as a measure of the popularity of your site.
However, all links are not equal. Below are a few important factors for quality inbound links:
1. The anchor text used in the link - Ideally, your links will have your keywords or variations of your keywords in the anchor text. For best results, mix it up - don't use the identical keywords for all of your links.
2. The trustworthiness of the linking domain - Links from reputable domains, particularly Government (.gov) and Educational (.edu) domains, are often considered more valuable by search engines than .com pages.
3. The popularity or page rank of the linking page - A link from highly ranked www.nytimes.com is considered to have more authority than a link from a poorly ranked website.
