Tradingview is a good website for everyone that wants to learn more about stocks. I really like their graphs and I love to see the good things that experts are sharing. I am using it since 9 months now and I would not switch to another platform. I use the free version.
I bought some clothes at asos.com but they were not my size, the support was really kind and helped me a lot with the return of the clothes. The refund was also pretty fast.
Clickfunnels is an amazing product, if you need to build a websites that needs to sell, than go with clickfunnels. For someone that has 0 experience in coding, this is what you should choose. It is a bit expensive but it is worth it.
I am very statisfied with crazy egg, it helps me to disvover things about my website that I did not know before, it would be really cool if the pricing would have been a little bit cheaper.
The free trial is pretty long and it gives you the possibilty to understand if it is a good product for you
The tool gives super suggestions! I like that it is so advanced but also easy to use for someone like me who is not very good at this stuff. The search is very easy and I really like the possibility to make hashtags collections.
