need your feedback - building an SEO webapp over here

Tell me what kind of functions would be important to you if, let's say, i have 1000 search results and can sort them by:
- how many times does domain1.com come up vs. domain2.com
- where does domain1.com rank on average vs. domain2.com
- how many times does the term "dog" come up in the title in all
- how many times does domain1.com come up in top 10 results
- how many times does domain1.com come up in top 20 results
- word count of titles in positions 1-20
- total results in SERPs for keyword
- how long has URL been on the first page (find sites that have "popped out of nowhere")
- which author name has the most articles written, according to google metadata
