Yahoo Site Explorer offline – LRT returns double link data

This is an open letter to our clients and prospective clients from Christoph C. Cemper, creator of the LinkResearchTools.


Yahoo Site Explorer Down per Nov 21 2011

As you probably know – Yahoo Site Explorer has stopped working yesterday per November 21.
Finally. This has been long awaited and postponed by over a year, at least for us.


Yahoo Site Explorer Offline per Nov 21 2011

Yahoo Site Explorer Offline went offline on Nov 21 2011


LinkResearchTools not affected

For you as a client this only means, that we now aggregate and validate link data from 23 instead of 24 sources.
The effect of Yahoo Site Explorer ceasing operations is mild based on our experience and test we conducted for
for the past months.


New Link Data Source = Double Link Data

Also note that in last week’s Link Boost update we also added two new
high quality link data sources to the mix (hence the jump from 21 to 24).

This means – for Superhero accounts – up to a double number of links for your research based on our tests.

Small Site Research Improved

Especially research on small websites profit from this as the discovery rate has been greatly improved
with this for small domains.

Small domain data is a big problem that many of the “monolithic” link tools fight with,
and will continue to do so, by concept. This is the reason why LinkResearchTools
aggregate so many different sources and validate them in real-time for you.
Every report is fresh.

So, the LRT results are fantastic for you as an SEO and
absolutely unique on the market today.


Sudden Link Spikes? No, better data! Same price.

If you wondered why you suddenly see more links than last week, this is why. The new strong link data sources we integrated for you as an ongoing
improvement of the product show full effect. This can also be seen in the new feature “Link Boost” we introduced last week.

Also if you set Link Alerts you probably see similar “boost” effects with more links. There you can use the metric “Google Update date” to  better gauge WHEN the link
was actually placed.

I hope I could clarify the “sudden link spike” that so many of you see because of this improvement and can calm you that it is probably not an unnatural link spike,
but a drastic improvement of the tools.


Double Link Data and more

These are great improvements, with

the doubling of the link data,

the Competitive Landscape Analyzer,

the SERP research tool

and the new Contact Finder

I think we really boosted the functionality
of the tools also in this year for you.

I’m especially proud on my team that made this happen,
but wait – there’s more to come!

Stay tuned. We’re not resting.

With this I wish you Happy Researching
and warm regards from freezing Vienna
