How to promote a site on Drupal with SEO?

To avoid spending time and energy learning all the nuances, I'd suggest considering the services of professionals. Here, for example, is a great solution: https://en.site-ok.com/services/buy-seo-for-drupal . This service will help you optimise your site for keywords, set up friendly URLs and meta tags, and improve its structure for search engines. SEO for a website is a long-term investment, and the sooner you start, the sooner you'll see results. It is important to realise that promotion will not give an instant effect, it usually takes a few months for traffic to start growing actively. But after 3-6 months, you will notice an improvement in the site's position in the output, and in a year you can expect consistently high traffic.

I have a website on Drupal and I started thinking about promoting it in search engines. I read that for Drupal you can set up friendly URLs, clean code and add meta tags, which helps SEO. But here's the problem - I'm not an expert in this topic at all, and it seems that it will be difficult to set up everything myself. I want to know from those who have already gone through it - is it realistic to do quality optimisation of the site on Drupal or should I turn to professionals? If someone can share experience or offer some good solutions, I will be very grateful. Maybe there are modules or tools that will help simplify the task? Also wondering how long it usually takes to see results?
