We have an SEO company telling us the first line in our robots.txt file should be this.
They're also saying that the unconventional sitemap URL of sitemapindex.ashx is not search friendly. So I have two questions. Are there any ramifications if we add that to our robots.txt file, why did Telligent omit it if it is a best practice (if indeed it is a best practice...or does it not even matter), and would there be any drawbacks of having a redirect rule that sends sitemap.xml to sitemapindex.ashx?
