I have entered my site (patioenjoyment.com) a few different times into the OSE and it never seems to find it, MOZ has found it because it has done the crawl test for me a few times, found some issues and I have been working on those. But I assume that if it is able crawl my site it should find it to run the OSE. It has come back with "**It looks like we haven't discovered established link data for this URL yet." everytime. **
Thanks,
Julie
