I use this site to check competitors website for backlinks. I was wondering how often the listing is updated. does anyone know of another free service like this. I am sure that there is one. Just wondering how others research competitors.
Here are the few links which helps you to find the back links fo any URL, build-reciprocal-links.com/backlink_checker_tool and backlinkwatch.com/index.php I hop this may help you.
Yahoo explorer is definitely the best tool for checking backlinks of other sites. Another tool is backlingwatch. Other tools may be available from time to time but most of them do not last long. Be aware that those tools (incl. yahoo explorer) list only backlinks to a page (not the whole site). So, if you check backlinks to the homepage example.com, you won't get the backlinks to other pages of the site such as example.com/dir/ .
Yahoo explorer lists : 1. amount of (indexed) pages 2. amount of backlinks As far as "pages" are concerned, they are the pages that are indexed by Yahoo. The actual amount of pages of the site may be higher if some pages are not indexed for various reasons (new pages, robot txt, duplication,...). Keep in mind that search engines consider subdomain as a separate site. Ex. https://siteexplorer.search.yahoo.com/search?p=http://www.digitalpoint.com/&fr=sfp Digitalpoint has 31957 indexed pages https://siteexplorer.search.yahoo.com/search?p=http://forums.digitalpoint.com/&y=Explore+URL&fr=sfp Forums.digitalpoint.com has 5624395 indexed pages.
In fact, as far as links are concerned, Yahoo explorer shows either links to "entire site" or links to "only this URL", as you prefer. I understand that links to entire site include subpages. They may include also subdomains only if the site has been authenticated (i. e. your own site). For further information, see: http://help.yahoo.com/l/us/yahoo/se...rer-21.html;_ylt=AgVg6N_ZKhkZ487Kxng5Z1voBiV4 Other backlink tools list only backlinks to a page (not the whole site).
Yahoo site explorer is one of the most known and used software.I also prefer google keyword tool for additional result.These two sites are closely perfect in giving me the data i need.
