You can sign up for a trial with 100 searches.
As for what is good, searches tend to pull up relevant info that is not buried under a bunch of seo shit. You can block, downgrade, and upgrade domains (I have blocked Pinterest from all my search results for instance). It’s just a very good experience. And long term I feel more confident in their user experience since their profit motivation is not tied to serving you up ads.
My biggest complaint is the 300 searches a month seems a little low.
But give the 100 free searches a shot. I have been very happy with them.
In China or the US?
