There are very favorable hosting rates for site hosting. But sometimes they are intimidated by traffic restrictions. We will understand how to determine whether the site will fit into the established framework.

## BANDWIDTH CALCULATION

A simple calculation can tell a lot of interesting things:

Required traffic = average number of page views x average page weight x average number of visitors per day x number of days per month x reserve.

The average number of visitors per day is the total number of visitors per month, you need to divide by 30.

- The average page weight is the average size of a single page file.
- The average number of page views is the average number of page views per visitor.
- Reserve is a safety factor that varies between 1.3-1.8.

We arrange the numbers, and get a rough estimate of the bandwidth that is required for your site.

## CALCULATION OF THE BANDWIDTH OF THE SITE FROM WHICH YOU CAN DOWNLOAD A FILE

The calculation is carried out in a similar way, only need to identify additional channels for download. Site bandwidth and downloads are easily calculated using the formula:

Required traffic = [(Average number of page views x average page weight x average number of visitors per day) + (average number of downloads per day x average file size)] x number of days per month x reserve .

The average number of visitors per day is the total number of visitors per month should be divided by 30

- The average page weight is the average size of a single page file.
- The average number of page views is the average number of page views per visitor.
- The average file size is the total size of the site files divided by the number.
- Reserve is a safety factor that varies between 1.3 – 1.8.

## EXCESS BANDWIDTH

Now you understand that there is a certain margin of safety, ranging from 30% to 80%, which is used in the calculation of throughput. The reason for this is that the bandwidth reserve is crucial, if necessary to withstand sudden spikes in traffic.

That is, the higher the backup rate, the more stable the server. So, it can cope with an unexpected jump in traffic that can erase all the differences between a successful and unsuccessful advertising campaign site.

For example, your article was on the first page of Google for the search query “iphone” – and the server does not cope with a sharp increase in traffic. That is how a good advertising campaign suddenly ended very badly.

## HOW TO DETERMINE IF A SITE NEEDS MORE BANDWIDTH?

As a rule, if the site is constantly busy and slow, this is the first sign that a higher bandwidth is required.

The probability that the provider simply does not have enough bandwidth reserve capacity is also not excluded. To solve this problem, it is necessary to increase the bandwidth, or switch to a dedicated server, since there is no need to share the bandwidth of the site with other hosting clients.

In addition, you can use file hosting services, which not only allows you to save an impressive margin of site bandwidth, but also make a profit for downloading your files.

## CONCLUSION

When choosing a suitable hosting plan, you should, in addition to the amount of bandwidth, pay particular attention to some details.

The frequency of the processor, the number of databases, RAM – this is just a partial list. In fact, without quality resources on these parameters – unlimited bandwidth loses its meaning.
