freeseoreport.comは安全ですか？

Site design has been plagiarised from ***** which, in my opinion, completely destroys it's credibility. Claims to have some of the world's largest companies as customers, which I very much doubt (due to the lack of trust I have for this site, since the design is an almost carbon copy of Woorank). On comparison with a Woorank report, there are a sizeable number of noticeable differences in the results. Some items are completely incorrect. For example mobile CSS, touch icons, GZip, and minified CSS/JS were not detected (which were present on the site I was testing). Despite being advertised as a free tool (as per the domain name) there are a number of fairly expensive plans for more advanced reports. I STRONGLY recommend that nobody should sign up to these as the free tool is woefully inaccurate. Instead look at a more reputable product like Woorank or Moz.
