Which text verification service is better?

Question

Search Engine Optimization

Greetings
There are several services for checking the uniqueness of texts on the network, I will not list them. The question arose about choosing a reliable service for checking the uniqueness of texts. I use text.ru and notice that sometimes it gives different results - at first it gave 90% uniqueness, after a couple of hours - 95%. I thought about alternatives, but how to choose a decent service, the best one available?!
I would appreciate links to a comparison of the quality of service verification, if any, as well as personal experience, opinions and assessments.

Answer 1

Yes, it seems like Advego always behaved well

Answer 2

Everywhere it is better to check 2 times.
Techt.ru - scans for a long time, but gives an excellent analysis of SEO, density, spamming, etc. If you are very picky about shingles, occurrences and other trifles, then this is the best option.
Advego - you need to set it up correctly and learn how to interpret it correctly. Good old Advego rarely fails me, but more often I use content watch.
Content watch - compared to the 2 above - scans faster.

Answer 3

Yes, advego plagiarism is the most proven and popular option, I haven’t seen anything better than it yet ...
