Frequently Asked Questions
What is a backlink checker and how does it work?
A backlink checker crawls the web and databases of indexed links to compile a list of external websites that link to a given domain or URL. It shows the linking domain, anchor text, link type (follow/nofollow), and domain authority of the source.
What is a backlink exchange and is it safe for SEO?
A backlink exchange (also called link swap or reciprocal linking) is when two websites agree to link to each other. Done naturally and in moderation between topically relevant sites, it's generally safe. Excessive reciprocal linking schemes violate Google's guidelines and can result in penalties.
How can I find backlink opportunities using this tool?
Enter a competitor's domain to see who links to them. Sites that link to multiple competitors in your space but not to you are prime outreach targets. The tool also flags broken links on competitor sites that you could replace with links to your content.
How many backlinks can I check for free?
The free tool shows up to 100 backlinks per domain check. The full LazySEO platform provides complete backlink profiles, link velocity tracking, toxic link detection, and link-building outreach tools.
What metrics matter most when evaluating a backlink?
The most important factors are: domain authority (DA) of the linking site, topical relevance to your content, whether the link is followed or nofollowed, anchor text, and the traffic the linking page receives. A few high-quality relevant links beat hundreds of low-quality ones.
