What are backlinks? SEO explained in 2 minutes
A backlink is a link from another site to yours. Google treats them as trust signals. Here is the essence, no filler.
A backlink (inbound link) is a link from another website to your page. In SEO, backlinks are an important authority signal: when relevant sites mention you, search engines tend to treat you as a more trustworthy source.
Why backlinks matter
Google does not only read your content. It also looks at who cites you. One link from a relevant site with real traffic beats ten links from empty pages. Backlinks help discovery (crawl), topical authority, and, indirectly, rankings on competitive keywords.
Dofollow vs nofollow (briefly)
- Dofollow: passes an authority signal to your page (the classic SEO link)
- Nofollow / sponsored / ugc: limits or labels the relationship; they can still bring traffic and brand mentions
- Do not ignore nofollow: a link in a strong article on a big site still has value even when it is not dofollow
Good backlink vs toxic backlink
- Good: relevant to your niche, real content, organic traffic, natural mention in context
- Weak/toxic: link farms, spam comments, low-value paid directories, shady PBNs
- Quantity without quality does not win. One editorial link on a serious site beats dozens of cheap bought links
How to earn backlinks the right way
- Publish content others want to cite: guides, data, case studies, tools
- Guest posts / industry collaborations with real value (not spam)
- Digital PR: news, launches, partnerships, mentions on client sites
- Fix unlinked mentions: find your brand cited without a URL and ask for the link
- Build a site worth linking to: speed, clarity, useful pages. Link building on a weak site is waste
Short rule: a backlink is worth it if the linking page would exist for real readers even without SEO.
Should you buy backlinks from a marketplace like Rixot?
Link marketplaces such as Rixot sell dofollow links placed in articles on other sites, often for a few dollars each. It is tempting, but Google's spam policies treat buying or selling links that pass ranking value as link spam. The risk is not only a penalty: cheap placements usually sit on sites with little real traffic, so they rarely send visitors either. If you pay for a placement, Google asks you to mark it rel="sponsored", which means it no longer passes ranking value.
