There are two types of links, internal and external, think of both as signposts to and around your website.
Link building is the process of acquiring hyperlinks from other websites to point at your own. These links are a way for users and search engine bots to navigate between pages on the internet and hopefully end up on your website.
Google and other search engines use these links to crawl the web and navigate from site to site and around the internal links on your website too.
There are many techniques for building links, and while they vary in difficulty, effective link-building is one of the hardest parts of SEO.
Learning how to link build well can shoot your website up the rankings gaining visibility for your chosen key phrases and gaining you, valuable customers.
When using Google, most people don’t look past Page 1 of the results so getting your website ranked by having a good link-building strategy is essential.
