External links are how search engines know your site is real and worth ranking
When another website links to yours, search engines treat it as a vote of confidence. A link from an established site tells Google and Bing that your content is worth showing to people searching for related topics. The more links you have from relevant, trustworthy sites, the higher you tend to rank for the terms those sites link you with.
This matters because search engines cannot visit every page on the internet every day. Links act as a path that leads them to your site and tells them what your pages are about. A site with no external links is invisible to search engines — they may never find it at all.
Building external links takes time and real effort. You cannot buy them from a service and expect search engines to count them. The links that move your ranking are the ones that come from people who genuinely want to point their readers toward your content.
Key Takeaways
- Links from established websites signal to search engines that your content is trustworthy and relevant, which improves your ranking.
- The best links come from sites in your industry or topic area, not from random directories or link-selling services.
- Creating content that other people want to link to — guides, original research, tools — is more effective than asking for links directly.
- Broken links on other sites are opportunities: you can contact the site owner and suggest your content as a replacement.
- Search engines penalize artificial link schemes, so focus on links that come from real editorial decisions, not paid placements.
Create content that other websites want to link to
The fastest way to earn links is to make something people in your field actually want to share. This means original research, detailed guides, tools, or data that solves a real problem or answers a question your audience is searching for.
If you run a plumbing business, a guide titled "How to Know When Your Water Heater Needs Replacement" is linkable because homeowners search for it and other sites (home repair blogs, real estate guides, contractor directories) will reference it. A page that just lists your services is not.
The content does not have to be long, but it has to be the kind of thing someone would cite. Original data, step-by-step instructions, checklists, and comparisons work well. So do tools — a calculator, a checklist template, or a diagnostic quiz that people can use and share.
Find sites in your industry and reach out directly
Once you have content worth linking to, identify websites that already cover your topic. These are sites your potential customers or readers already visit. Search for phrases related to your business or topic and look at the top-ranking pages — those sites are your targets.
Look for pages that mention your topic but do not link to a resource that covers it deeply. If a home improvement blog mentions water heater lifespan but does not link to a detailed guide, that is an opening. Contact the site owner or editor with a specific note: mention their article, explain why your content would help their readers, and include a link.
Keep the message short and genuine. Do not send a template email to fifty sites. Site owners can tell, and they ignore it. A personal note that shows you read their work gets a response rate of 5 to 15 percent. A template gets close to zero.
Look for broken links on relevant websites
Broken link building is a concrete tactic: find a page on a relevant site that links to a resource that no longer exists, then suggest your content as a replacement.
Use a tool like Ahrefs, SEMrush, or the free Broken Link Checker browser extension to scan a competitor's website or an industry resource site for dead links. When you find one, check whether your content covers the same topic. If it does, contact the site owner and let them know the link is broken, then suggest your page as a replacement.
This works because the site owner already wanted to link to something on that topic — they just need a working link. You are solving a problem they have. The email is straightforward to write: "I noticed your page on [topic] links to [dead URL]. That resource is no longer available. I have a guide on the same topic that might help your readers: [your link]."
Contribute to industry publications and directories
Many industry websites, trade publications, and professional directories accept guest posts, informed contributions, or business listings. These come with a link back to your site, and they reach an audience already interested in your field.
Look for publications your customers read. If you are a financial advisor, write for a personal finance blog. If you run a dog training business, contribute to a pet care website. The publication gets free content, their readers get information, and you get a link from a site in your industry.
Some directories charge a fee to list your business, but many do not. Check whether the directory is actually visited by real people — a directory with no traffic does not help your ranking. Look at the site's own search engine ranking and traffic estimates using a free tool like Ubersuggest or Moz's free toolbar.
Build relationships with other site owners in your field
Links often come from relationships, not cold outreach. If you regularly interact with other site owners — commenting thoughtfully on their posts, sharing their work, mentioning them in your own content — they are more likely to link back to you.
Participate in online communities where your audience gathers. Answer questions on forums, contribute to discussion boards, and mention your own content when it is genuinely relevant. When you help people solve problems, some of them will visit your site and link to it.
If you find a site owner whose work you respect, reach out and start a conversation. Share their article with your audience. Ask them questions about their work. Over time, these relationships can lead to natural linking opportunities.
Avoid link schemes and paid link services
Search engines actively penalize sites that buy links, trade links in bulk, or participate in link networks designed purely to boost ranking. If you purchase links from a service, Google will eventually detect it and your ranking will drop — sometimes dramatically.
The same applies to link exchanges where you agree to link to Site A if they link to you, especially if the sites have nothing to do with each other. A few reciprocal links between related sites are normal. Dozens of them signal to search engines that you are gaming the system.
Paid directory listings are a gray area. A legitimate directory that charges a fee and actually serves users (like the Better Business Bureau or a professional association directory) is fine. A directory that exists only to sell links and has no real traffic is not. If the directory would not be useful without the promise of ranking benefits, it is probably a scheme.
Frequently Asked Questions
How long does it take to see ranking improvements from new links?
Search engines typically discover and process a new link within days to weeks, but ranking changes often take longer — usually one to three months. The delay depends on how often the linking site is crawled and how many other ranking factors affect your page. Do not expect when ready results.
Do links from social media count toward my ranking?
Links from Facebook, Twitter, Instagram, and LinkedIn do not directly improve your search ranking because search engines treat them as social signals, not editorial links. However, content that gets shared on social media often gets linked to by news sites and blogs, which do count.
Is it better to have many links from small sites or a few links from big sites?
A link from a large, established site in your industry is worth more than ten links from small, unrelated sites. Search engines look at the authority and relevance of the linking site, not just the number of links. One link from a major industry publication can move your ranking more than dozens of links from random directories.
What if a competitor has way more links than I do?
More links does not always mean higher ranking — relevance and quality matter more. If a competitor has thousands of old, low-quality links, they may rank lower than a site with fifty high-quality links from relevant sources. Focus on earning links from sites your audience actually visits, not on matching your competitor's link count.
Can I ask someone to remove a link to my site?
Yes. If a link comes from spam, an unrelated site, or a paid link service, you can contact the site owner and ask them to remove it. You can also disavow links in Google Search Console, which tells Google to ignore them when calculating your ranking. Use disavow only for links you cannot remove yourself.
