If Google
Webmaster Tools Link data is worthy enough for a for having a successful link
cleanup is not relatively new topic in the SEO industry. To understand the
point in a better way it is essential to go into the background of the topic.
Background
History
From
various discussions and debates held on the topic last year it emerged that it
was enough if one used the GWT data. Another point that came into focus was
that the links which went missing from the report were not significant enough.
Later it
was also added that using the third party tool was not necessarily a bad
idea, as by using the same a greater ability to process the link data can
be achieved and it becomes relatively easy to look out for problematic areas.
These problematic areas might include issues as spammy patterns and anchor text
abuse issues.
