Yahoo Site Explorer on Steroids, with a Machine Gun… aka QBL

Firstly you get a tonne of useful information enabling you to easily analyze competitor backlink profiles… some of the data it chucks at you would have taken ages to put together in Excel to make the appropriate comparisons. So at the very least it’s a time saver.

Just like with the Backlink Profiler tool it has the ability to sort and filter by certain metrics. It goes out and grabs lots of links, nice and fast, and then brings them back to you like a faithful hound placing them at your feet… but on your screen in a list instead.

With a quick glance you can see if each link meets your criteria, what anchor text is within it, how many backlinks are pointed to the page and site, and you can compare IP’s to make sure the domains you’ve chosen are hosted separately.

Many SEO Toolkits there reacted to Yahoo Site Explorer going offline, but CEMPER.COM‘s Link Building wonder weapon stand out – not only because they just doubled their link data volume, also because of the advent of a new Ferrari-like tool to become a full-fledged replacement (and then some) for Yahoo Site Explorer. Enter QBL – the quick backlinks tool!

Starting multiple QBLs is easy as cake from existing reports in the Link Research Tools and the QBL itself, by simply selecting URLs and clicking the >Start QBL link at the bottom of the report data table.

The QBL visualizes your link data in an easy understandable way supported by nice looking charts. If you’re not into sifting through all the links individually, the charts which are part of the QBL help you get a quick overview quickly.

The Backlink Link Profile Tool

This tool is actually my favourite and it’s also something that as an SEO Consultant I have neglected to really dig into in the past, but now more than ever having a good link profile is important and this tool really does display it quite effectively. The anchor text breakdown, the link status, deep link ratio and TLD breakdowns are all nice, but the real winner is the theme breakdown (at least in my eyes). Whilst I don’t expect that this is entirely accurate, it does let you know if you need to diversify or if you need more specialist niche relevant links. This certainly saves inordinate amounts of time. A close second would be the anchor text popularity which again is a huge time saver. The issue I’d have with this tool is that you won’t really need to use it much and if you’re starting a campaign from scratch you could really keep tabs on what is being built at least for the most part. I’d say that it may be something that you want to check once every month or so and adjust your link strategies accordingly. To cut to the point this IS a GOOD tool and well worth a play.

LinkResearchTools’ reports are quite easy to set up but take some time to process. Depending on the initial setup it can take the internal crawlers up to one hour to get you the data. The good thing about these “live crawls” though is that all the data is as “fresh” as possible. I’ll use the Backlink Profiler to explain how the toolkit works because it’s a tool everyone who has a LinkResearchTools subscription uses a lot.

LinkResearchTools contains 10 tools. Each tool gives you a specific type of report. Altough it might be a little confusing when confronted with it for the very first time it’s quite easy to get into it after watching the tutorials and videos on LRT’s website.
