Visually, the website looks good. I'm not interested too much in the back end, and quite frankly, neither is Google nowadays (or not as much as before). I do have a few interface suggestions though.
1. Hide that chat. If it's not in use, it should be invisible. This is part of the user experience on your website. (I use Tawk, and from my experience it just acts as a gateway and an excuse for customers to submit a contact form anywhere on the website without actually going through the website).
2. The verbiage in your Terms of Service is off if your target audience is English. I understand that you work for a multi-national website, but Google will penalize grammar. It's not poor, it's just a bit off. It's perfectly understandable, so please don't take this advice out of context. I'm just being blunt.
3. More on the verbiage, take a look at this excerpt in your footer.
"SEO Service Provider is a Google partner company, provides all kinds of Search Engine Optimization (SEO), Search Engine Marketing (SEM) and Social Media Marketing (SMM) & Optimization (SMO) services. We do everything manually. No blackhat or automatic Sorry!"
To break it down,
1. The first sentence is too long and has almost no breaking points. It's hard to follow.
2. The second sentence after the comma should be it's own sentence, but as it stands it's a sentence fragment.
3. "SEO Service Provider is a Google partner company" - You can be a company that's a Google partner, but you can't be a Google Partner Company. The wording sounds off.
4. You should keep parentheses, blackhat, and apologies outside of the footer since this content will be indexed on each page. This will raise your key phrase score for these terms which is why you want your footer to be pristine. (Key phrases, not keywords. They are different.)
Hope this has been insightful. I had fun looking at your website, good work with it.
