The question of determining the traffic of other people's sites worries most webmasters. The main interest is caused by competitors' sites or sites, the direction of which seems to be promising for creating another portal.
Methods for determining traffic to other people's sites
Most sites have traffic counters, which are displayed at the bottom of the pages. Most people use Yandex. Metrica and Liveinternet services. If there are pictures from them on the page, then the number in the middle means the current attendance for this day at a given time.
Both services are updated when the page is loaded and, accordingly, the counter code. Losses are no more than 1%, which is quite accurate. This method is only available for counters with graphical output on the page. If you do not see such pictures, then you should open the code of the main page in a separate browser tab and look for the lines indicating the place where the counter starts.
In this case, you will not be able to view the statistics under any circumstances, but at least you will know what service the site owner uses.
It so happens that a webmaster uses a Liveinternet counter without numbers. In this case, you can try using the following address: counter.yadro.ru/values?site=. After the equal sign, you must write the site address without https:// www.
Perhaps, in this case, you will be shown traffic statistics if access is open to all users.
To be sure of all the possibilities used, you can visit any site statistics site. Very often statistics taken from the same sources are indicated on them in a separate section. But sometimes it happens that there is no way to look at the site, and the Yandex. Metrica statistics are still displayed as a number.
Non-standard methods of traffic analysis
There is a foreign website rating service alexa.com. It contains all sites with a traffic of 2 thousand visitors. The lower the site's rating, the more visitors there are per day. After selecting the desired region, you just need to enter the site address in the search box and, if it has a rating, then you will find sites in the list next to it.
They may have open counters, which means that the approximate attendance of the desired site will be clear. The difference can be no more than 10%.
If the site is on a commercial topic and you understand the approximate queries to the search engines on which it is located, you can calculate the approximate traffic yourself. To do this, you need to use the Wordstat services from Yandex. Depending on the number of impressions for keywords and the average location of the site in the search engine results, you can make approximate calculations.
