If you are developing your own website, the first priority is to find out that it is indexed by search engines and not banned. In Runet, one of the leading search engines is Yandex. Use a simple algorithm that will allow you to find out if your site is on Yandex's blacklist.
So, you are in doubt if your site is in the Yandex directory. The simplest way to find out if this is the case is by the search engine itself. First, open the page of the search engine https://www.yandex.ru/. Most likely, you have already used this service.
Next, all you need is the link search code. It must be entered in the search bar, and not in the address bar of the browser. The text of this request looks like this: # url = "www.your site.rf *", where "your site.rf" is the address of your site. As you may have noticed, the address fits in without the permission of https://. Such a record of the search query will allow you to make a search exactly at the address, which is required.
Check out the search results. The first result should be a link to the home page of your site. If not, then most likely he is blacklisted. The reasons can be very different. Alternatively, the domain is banned, that is, it was already in the blacklist when you bought it. It is possible that malicious information has entered your site - a virus program or suspicious content. After all, the site could have been banned by accident.
In any case, if your site is banned, you will need to contact Yandex support to find out the details. This can be done at
Your site may simply not be indexed by the search engine. It takes a robot some time to find and index your site. To make sure that this is not the case, follow the link https://webmaster.yandex.ru/addurl.xml, enter the address of your site's main page in the URL bar and follow the simple instructions.
If the service reported that robots were sent to analyze the site, then, most likely, it will appear in Yandex catalogs in a couple of days. Next, you have to move your site up in the search engine, regularly filling it with high-quality and unique thematic content.
