I never liked auto-approved blog comments and bad redirects, so that's one way of knowing which links are bad (these are particularly bad for new sites that don't have backlinks yet, if all you have is AA comments and crappy redirects I don't think you'll manage to rank any time soon)
There are more types of bad links than these 2, obviously. But I'll let other people share them

Bad backlinks often come from spam or unrelated sites like gambling , or low-quality directories. If you see random sites linking to you in bulk , that is a warning sign. Tools like search console can help spot them early.

Backlinks should be built based on your target landing pages. Links from low-quality sites or those that violate SEO standards are considered toxic backlinks.

To spot harmful backlinks, focus on anything that looks unnatural or low quality. Warning signs include links from spammy or irrelevant sites, pages with thin or copied content, too many exact match anchor texts, links coming from link farms or PBNs, and sudden unusual spikes in backlinks. You can check your backlink profile using tools like Google Search Console, Ahrefs, or SEMrush. If a link feels unrelated, untrustworthy, or clearly built just to manipulate rankings, it’s probably a bad link.

Harmful backlinks usually come from spammy, low-quality, or irrelevant sites and often appear in unnatural spikes or with over-optimized anchor text. Focus on patterns, not single links. Use tools like Google Search Console to monitor your profile Google usually ignores most bad links anyway.

You can usually spot harmful backlinks by checking the quality and relevance of the websites linking to you. If links are coming from spammy websites, unrelated niches, copied content blogs,link arms or pages filled with ads and outbound links, they can be a bad sign.

In my experience, bad backlinks can indeed come from a variety of sources, including spammy sites, low-quality directories, and unrelated niches. What I've seen is that these links often have certain characteristics, such as thin or copied content, excessive exact match anchor texts, or suspiciously high outbound links. It's also worth noting that link velocity is important - sudden spikes in backlinks can raise red flags. Tools like Search Console, Ahrefs, or SEMrush can help you monitor your backlink profile and identify potential issues. I've found that focusing on patterns rather than individual links is key to identifying harmful backlinks. By being proactive and regularly checking your backlink profile, you can help mitigate any potential damage to your SEO.

1. Don't build backlinks from irrelevant places.
2. Think twice before you build any backlinks.
3. If you really feel your competitors sending backlinks from harmful sites, you must find those links and tell in google web tools to disavow those links.

Bad ones usually:
- From irrelevant or spammy sites
- No traffic, just made for links
- Weird anchors (over-optimized keywords)
- Too many links from the same type of sites
If it looks unnatural, it probably is.

Spotting toxic backlinks is mostly about logic and a few key metrics. You’re looking for links that feel out of place or manipulative. Generally, any link coming from a completely irrelevant niche—like a gambling site linking to your cooking blog—is a red flag. You should also watch out for spammy anchor text that uses over-optimized keywords or gibberish, as well as sites with high spam scores on tools like Ahrefs or Moz. Links buried in footers or hidden via CSS are also classic signs of a bad neighborhood. That said, don't sweat the small stuff; Google is usually smart enough to ignore random bot links without you needing to intervene.

Check for spammy backlinks from irrelevant niches, low quality directories, PBNs, or sites with high outbound links and no real traffic.
Also watch for over optimized anchor text, foreign language links, and sudden link spikes use tools like GSC/Ahrefs to audit and disavow if needed.

Look for links from deindexed domains, malware/redirect sites, spun content blogs, or pages with zero organic keywords these are clear red flags.
If most links have exact match anchors or come from unrelated countries/IPs, audit them in GSC and disavow the toxic ones carefully.

focus on pattern not single link. lots of low quality domains, same anchors, irrelevant niches = red flag. hacked sites, footer spam, auto blogs also bad. use Ahrefs or Semrush to spot spikes. most times google ignores them, only disavow if extreme

Check for backlinks from spammy, low DA sites use tools. Look for unnatural anchor text, sudden link spikes, or unrelated niche links they can trigger penalties.

If they are spamming you from websites that either are trash or don't have relevance then these are the backlinks you should watch out for. You can use either Semrush or Ahrefs to spot those links.

Sometimes I spot bad links faster by sorting by newest links first and checking for any sudden weird domains that stick out like a sore thumb. If a batch pops up overnight, it’s usually a hint something sketchy crawled in. I also like checking anchor text clouds because any odd spike in exact match stuff is a red flag before digging deeper.

Harmful backlinks usually come from irrelevant, spammy, or low-quality sites like link farms, PBNs, or auto-generated blogs.
