To participate in the action, it is enough to write a post about the action itself and put a link to the page with its terms.
I should note that not every blog can claim the main prize. To do this, the blog must exist for more than 3 months, have more than 50 subscribers, have attendance above 50 people per day and be dedicated to SEO, SMO and other moneymaking (more here).
While only 3 blogs got the prize, there are still 17 places left. Here, the principle is that whoever got up earlier, that, and sneakers, so if you want to use free hosting for the next year, I advise you not to delay 😉
