What Is a Backlink? Meaning, Types and Why They Matter (2026)
What is a backlink? A plain-English guide to backlink meaning, dofollow vs nofollow, why backlinks matter for SEO, and how to get and find them.
A backlink is a link on another website that points to a page on your website. Search engines use backlinks to discover pages and as one signal of how trusted and relevant a page is.
Example: if site A links to your page, that link is a backlink to you. So if a food blog in Pune links to your recipe page, you have a backlink from that blog. People also call them inbound links or incoming links.
Backlinks are one of the oldest ideas in search. Google was built around the observation that links between pages work a bit like citations in research papers: a page that many other pages link to is probably worth looking at. That idea became PageRank, and links still play a role in how Google discovers and ranks pages today.
How a backlink works
A link has two parts that matter for SEO:
- The URL it points to. This tells search engines which page the link is about.
- The anchor text. This is the clickable text, such as "best filter coffee in Chennai". It gives a hint about what the linked page covers.
A link can also carry a rel attribute such as nofollow, sponsored or ugc. These tell Google that the site does not want to vouch for the link, that it is paid, or that it was added by users.
Dofollow vs nofollow backlinks
| Dofollow (followed) | Nofollow, sponsored, ugc | |
|---|---|---|
| What it looks like | A normal link with no rel attribute | A link with rel="nofollow", "sponsored" or "ugc" |
| Ranking signals | Can pass ranking signals | Treated by Google as a hint; may or may not be used |
| Discovery | Helps crawlers find your page | Can still help discovery and referral traffic |
| Typical sources | Editorial articles, resource pages, partner sites | Comments, forums, social profiles, paid placements, many lookup pages |
A natural backlink profile has both kinds. We cover the difference in detail in dofollow vs nofollow backlinks.
Why backlinks matter for SEO
Backlinks do three separate jobs, and it helps to keep them apart.
1. Discovery
Search engine crawlers move around the web by following links. If no other page links to your site, crawlers have fewer ways to find it. A new domain with zero backlinks can still be found through a sitemap submitted in Google Search Console, but links give crawlers more paths in.
2. Ranking signals
Google has said for years that links from other sites are one of many signals it uses to understand how important and relevant a page is. A link from a respected, related website is a much stronger signal than a link from an unrelated page that nobody visits.
Be realistic about this. Google does not publish exact weights, and links are only one factor alongside content quality, relevance to the search and page experience. A thin page with lots of links can still lose to a genuinely helpful page with few.
3. Referral traffic
A good backlink sends real visitors. A link from a popular Indian news site, a niche forum thread or a well-read newsletter can bring customers directly, whatever it does for rankings.
What makes a good backlink
Not all backlinks are equal. In general, a backlink is more valuable when:
- The linking site is relevant to your topic.
- The linking site is trusted and gets real traffic.
- The link sits inside the main content, not hidden in a footer.
- The link was given freely by an editor, not bought or swapped.
- The anchor text describes your page naturally.

Backlinks vs internal links
A backlink comes from a different website. An internal link connects two pages on your own site. Backlinks bring signals and visitors from outside; internal links spread that value around your site and help crawlers find every page. See internal links vs backlinks for how to use both.
How to get backlinks
You do not need a big budget. Start with links that are easy and legitimate, then work towards the ones that move rankings:
- Business profiles and listings. Create a Google Business Profile if you serve local customers, and list your business on reputable directories in your country and industry.
- Social and community profiles. Your company pages on LinkedIn, YouTube or GitHub usually allow a website link.
- Partners and suppliers. Ask businesses you already work with to list you as a client, stockist or partner.
- Useful content. Guides, data, tools and templates are the things other sites link to without being asked. This is where long-term rankings come from.
- Outreach. Guest posts on relevant sites, broken link replacements and local PR all earn editorial links with some effort.
Each of these produces a different kind of link. Our guide to types of backlinks explains which ones matter most.
There is also a quick discovery step for new sites. Backlink Generator submits your URL to public lookup pages such as site statistics, WHOIS, SEO analysis and archive pages, which gives crawlers more paths to your domain. These links are mostly nofollow: they help discovery, but they do not guarantee rankings and are not a substitute for earned links. Your first run of 100 links is free with a free account; Pro gives unlimited runs. Read what discovery backlinks are before you use them.
How to find your backlinks
The free Links report in Google Search Console shows which sites link to you, which pages they link to and the anchor text they use. Bing Webmaster Tools and third-party checkers add a second view. Our step-by-step guide on how to find backlinks to your website covers all the free methods, including how to check competitors.
To confirm a single link, paste the linking page into our free Link Checker and see whether your link is there and whether it is dofollow.
What to avoid
Google's spam policies treat links made mainly to manipulate rankings as link spam. That includes buying links that pass ranking credit, large-scale link exchanges, and low-quality directory or comment links stuffed with keywords. At best Google's systems ignore links like these; at worst they lead to a manual action against your site.
FAQ
What is a backlink in simple words?
A backlink is a link from someone else's website to yours. If site A links to your page, that is a backlink for you.
Is a backlink the same as an external link?
It is the same link seen from two sides. For the site that publishes it, it is an external (outbound) link. For the site it points to, it is a backlink (inbound link).
Do I need backlinks to rank on Google?
Not always. Pages can rank for specific, low-competition searches with few or no backlinks if the content matches what searchers need. For competitive topics, backlinks from relevant sites usually make a real difference.
Are nofollow backlinks useless?
No. They can send visitors, build brand visibility and help crawlers find your pages, and Google may use them as hints. They just should not be your only kind of link.
How many backlinks do I need?
There is no fixed number. It depends on how competitive your topic is and how strong the pages already ranking are. See how many backlinks you need to rank.
Key takeaways
- A backlink is a link from another website to yours; search engines use backlinks for discovery and as one ranking signal among many.
- Dofollow links can pass ranking signals; nofollow, sponsored and ugc links are hints. A natural profile has both.
- Relevance, trust, placement and natural anchor text make a backlink good, not raw numbers.
- Build links through profiles, partners, useful content and outreach; use discovery links only to help new pages get found.
- Check your backlinks for free in Google Search Console, and avoid paid or spammy link schemes.
