SimilarWeb gives me different statistics then Google Analytics does?

[five-stars]

So basically I'm trying to find information about a site I market and these 2 platforms give me completely different stats.
Moreover, I added "SimilarWeb" as a google extension tab and it gives me info that the exact same site doesn't.
Here are pictures:

A picture from google analytics. This is for the whole April month. Shows me I had only 16 visits.



The Smilarweb website. It doesn't give me any info.



And here is the stats the extension gives for April which is around 80 people!






What are the correct statistics and is the extension just broken?

Similar Web doesn't actually have access to sites to get their traffic information. It makes guesses based on data they collect.

Google Analytics is tracking the actual visitors to the site.

Most sites what they do is just guessing based on data collected(many times) from other sites, it is called Web scraping.

The most accurate is google analytics (that I know of) and still, is not 100% accurate. (but not even your own stats) There are so many variables that is really hard to get it 100%.

Go with the stats provided by Google Analytics because it gives accurate information about Website traffic. Similar Web is nothing compared to Google Analytics, it just gives the random estimation of traffic. So go with the Google Analytics.

I have to agree and my opinion is that you shouldn't be trusting SimilarWeb to be accurate at all. It revolves around making estimated guesses and it can be way off from the real results... that's why I would definitely go with the results that Google Analytics shows. I don't think that either is 100% accurate but there's no such tool that would be able to give you that data.

Google Analytics is your best bet at actually getting the most reliable and accurate stats for your websites. Ignore the SimilarWeb because it won't give you the right feedback.
