1. SEO Wiki
  2. Backlinks



Backlinks, also known as inbound links or incoming links, are links from other websites to a specific webpage on your site[1]. They are important for search engine optimization (SEO) because search engines use them as a way to measure the popularity and importance of a website.

Types of backlinks

There are two main types of backlinks:

  • Do-follow links: These are the most common type of backlink and they pass along link juice to the linked website, which can help to improve its search engine rankings.
  • No-follow links: These links do not pass along link juice and are often used when linking to untrusted or low-quality websites. They still can be valuable in terms of referral traffic.


It's important to note that not all backlinks are created equal. The quality of the linking website, the relevance of the linking website and the relevance of the link in terms of the context is important to determine its quality. Search engines use various algorithms and ranking factors to determine the quality and relevance of backlinks, and they can penalize websites that engage in link schemes or other manipulative tactics.


To improve the quality of your backlinks, it's important to focus on building relationships with other websites in your niche, creating high-quality content that others will want to link to, and actively seeking out opportunities to get backlinks through guest blogging, broken link building and other tactics.

Importance for SEO

Backlinks are important for SEO because they indicate that other websites consider the content on your website to be valuable and relevant. When a website includes a link to another website, it is considered a vote of confidence in the content of the linked website. Search engines use the number and quality of backlinks as a way to measure the popularity and importance of a website, with the assumption that a website with more backlinks is more likely to be an authoritative and credible source of information.

There are several ways in which backlinks can impact SEO:

  • Page Rank: Google uses PageRank, which uses backlinks as a way to rank web pages. The more high-quality backlinks a page has, the higher it is likely to rank in search engine results.
  • Increase website visibility: Backlinks can help to increase the visibility of your website, by making it more likely to appear at the top of search engine results for relevant keywords.
  • Referral traffic: Backlinks can also drive referral traffic to your website, as users click through to your site from the linking website. This can lead to more engagement, more pageviews and ultimately more conversions.
  • Branding: Backlinks can also help to build your brand and establish trust and credibility with both users and search engines.
  • Competitive edge: Having backlinks from authoritative websites can give you an edge over your competitors and help you to outrank them in search engine results.

Link building is the process of acquiring links to a website with the goal of improving search engine rankings. There are a variety of tactics that can be used to build links to a website, here are a few of the most common:

  • Content marketing: Creating high-quality, valuable content that other websites will want to link to is one of the most effective link building tactics. This can include blog posts, infographics, videos, and other types of content.
  • Guest blogging: Writing articles for other websites in your niche is a great way to get backlinks and build relationships with other websites in your industry.
  • Broken link building: Finding broken links on other websites and suggesting your own content as a replacement can be a great way to get backlinks.
  • Resource page link building: Finding resource pages on other websites in your niche and reaching out to the website owner to suggest that they include a link to your website.
  • Social media marketing: Building a strong presence on social media platforms can help to drive traffic to your website, which can lead to more backlinks.
  • Directory submissions: Submitting your website to online directories can be an easy way to get backlinks, but the quality of these links can vary widely.
  • Testimonials and reviews: By providing testimonials or reviews for other websites or products, you can sometimes get a link in return.
  • Press release: By issuing a press release and getting covered by media, can help you to acquire backlinks.
  • Influencer marketing: By working with influencers in your niche, you can leverage their audience and get more visibility, and potentially backlinks.
  • Partnering with other websites: By partnering with other websites in your niche, you can get backlinks through reciprocal link agreements.
