In SEO backlinks are the single most precious resource. That's why
website promoters spend most of their time hunting for links. Searching
for link sources by hand is no longer an option. Whether you want to
research your own link profile or scan the links of your competition you
need to use backlink checkers for this. That's why backlink checking apps
are among the most popular SEO tools.
To help you in your quest for links here's a list of most popular
backlink checking tools and software (both free and paid).
1.Yahoo! Site Explorer
The grand daddy of all backlink checkers and perhaps the single most
widely used SEO tool on the planet. Yahoo! Site Explorer is great for
running quick checks on sites' ranking profiles. It's free and very
straightforward to use: you enter the url of the site you want to check
and Site Explorer generates a list of pages linking to it.
There are options that let you exclude the internal links coming from
same domain or subdomain. You can also use advanced search operators such
as site:/-site: command to check/exclude links coming from a particular
website or all sites with certain TLDs (.coms,.edus, etc.)
Note: Yahoo! Site Explorer lets you check only 1,000 links per domain
regardless of how many backlinks the site actually has.
Backlink Watch is an online backlink checker that helps you not only see
what sites link to a page, but also gives you some data for SEO analysis,
such as the title of the linking page, the anchor text of the link,
whether the link is dofollow or nofollow, etc. The tool pulls the list of
links from Yahoo! Site Explorer, so don't expect wider or different
Webconfs offers a collection of free online SEO tools. Two of them are
designed for backlink research. The first tool is called Backlink Anchor
Text Analyzer. It shows you what pages are linking to a particular domain
and with what anchor texts. If there are several links on a page you'll
see all the anchor texts used on each page. The second tool is Backlink
Summary. It does exactly what its name suggests - gives you a summary of
the domains linking to a page and shows you how many links are on each.
Just like Backlink Watch, Webconfs tools are also powered by Yahoo!, so
the results are the same and also limited to 1k links per domain.
4.SEO SpyGlass - Majestic SEO - Linkscape
If you're really serious about SEO you need to have some more solid
backlink checkers at your disposal that would let you dive deeper into
the link index, check more links and gather more data for analysis.
That's where tools like SEO SpyGlass, Majestic SEO and Linkscape come in
handy. These three tools can dig up much more backlinks to a site than
any other backlink checkers out there. The difference between them is
that Majestic and Linkscape rely on their own crawlers and link bases
while SEO SpyGlass queries a vast number of search engines and uses
advanced search operators to find more links.
Both approaches have their strong points. Using their own crawlers allows
gathering larger number of backlinks but also makes the service more
expensive both for the company and for the end user. Plus large data sets
are usually harder to analyze and make use of. The search engine based
approach of SEO SpyGlass gets you only the links that search engines
display resulting in a bit smaller link profile but you can run unlimited
backlink checks at no additional cost and the data you get is more
