Backlinks are one of the most prominent focal points of any webmaster's struggle to get their website noticed by the Internet at large. Google and other search engines use them both to index new websites and to assess how relevant their contents are to specific demographics. Ideally, a website would accrue many "quality" backlinks pointing to it from other established websites and domains so that search engines could be compelled to have it listed above potential competitors in SERPs. The ranking algorithms used by search engines are best able to make this determination if they can effectively associate a site's content and infrastructure with a wide variety of backlinks pointing to it. This is especially true if the content itself has been optimized well for SEO.
Of course, the algorithms do not reward a website with high SERP positions strictly based on the raw number of backlinks the indexing mechanisms happen to find while combing over the Internet's digital landscape. Since websites would be attaining success based on how many spam backlinks they would be accruing otherwise, Google naturally ignores duplicate links that appear in large groups on automated sites. In general, algorithms are most likely to respond positively to whatever awareness gets spread on the site's behalf by word of mouth, but the webmaster needs to stimulate this spread with a more hands-on approach.
Relying on outreach and PR to convince other websites to talk about and link to one's own site is the most direct method of creating backlinks that will satisfy the standards of mainstream search engines' indexing algorithms. Sometimes, the webmaster may be able to earn the privilege of writing a guest post on another domain. There are many SEO agencies that offer paid services that create high-quality backlinks though these and other forward-facing methods. Naturally, there would barely be any benefit in paying a firm to create backlinks that come across as the sort of spam that Google has trained itself to ignore, so one should carefully look over their options regarding which firms to hire and which service bundles to subscribe to.
