When it debuted last year, we called Research Central an SEO‘s dream mashup tool. Now it’s even more — it’s Grand Central Station for all your website and keyword research. Plus, we made it even more powerful with custom analyzers. Then we added reports.

The updated Research Central is live in your account now. Here are four things to check out first:

1. One input field for all research
2. Custom quality analyzers
3. Reports and exports
4. New data sources

1. One input field for all research

Click on the Research button in the Raven app. That takes you directly to Research Central. Then enter any URL, domain, keyword or phrase into the single input field. It’s just that simple.

What comes up first is the Summary page. Here’s what a Summary page looks like for a Domain:

Note that the tabs across the top of Research Central change based on what you entered in the input field. You’ll only see the tabs that are relevant to what you’re researching.

2. Custom quality analyzers

Raven has long had a Quality Analyzer tool that’s extremely useful for proposals or benchmarking campaigns. It had one huge limitation: the metrics that weighted its score couldn’t be changed.

Now they can.

The new Quality Analyzer puts you in control of your algorithm for evaluating websites. You can choose the metrics that matter most to you, weight their influence and then name and save it as your custom analyzer.

You can set ranges for each metric that determine if the metric is in low, middle or high territory. The analyzer view then displays metrics in color (green, yellow or red — i.e., low, middle or high) depending on where each metrics falls in its respective range.

You can add as many analyzers as you want. For example, an analyzer to focus on metrics for proposals.

Or an analyzer for social metrics.

After you create your custom analyzers, you can use those scores to evaluate and report on any domain you’re researching with Research Central — including competitors.

3. Report and export

Raven users have wanted to report on and export data from Research Central since it debuted. We’re excited to announce you’ll be able to create PDF reports from any data and export it from Research Central.

4. New data sources

We’ve also added a new data partner – WordStream – to Research Central. That means Research Central is powered by authorized data from SEOmoz, Majestic SEO, Google AdWords, OpenCalais, Wordtracker and WordStream.

Six data sources, one tool.
