Video lesson No. 3 - Determining the level of trust in sites

In search of products that interest us, we often turn to the Internet for help. And this is quite logical, because often it is online stores that offer us many useful things and are able to satisfy all our needs.

Increasingly, Russians are making purchases in foreign online stores. At the time of searching, the buyer’s path often comes across both world-famous sales platforms and little-known sites. They showcase great deals and the buyer's temptation increases.

When making a purchase in a domestic online store, we can choose cash on delivery and, if necessary, return the goods. In the case of foreign retailers, things are much more complicated, and customers almost always expect a “pig in a poke.” Therefore, before placing an order, you need to make sure that the foreign online store is reliable.

How to evaluate the reliability of a foreign online store

It is not clear why, but since ancient times the opinion has been established that in developed countries Defective, faulty or counterfeit products are not sold. There is also an opinion that goods from abroad are necessarily of high quality. However, this opinion is not entirely correct, because even in developed countries there may be low-quality products, and Chinese stores“encrypted” under American and European. These are the “honest” sellers you should be wary of.

First steps on an unknown site

1. First of all, when you go to the store website, familiarize yourself with its main subsections, carefully read the sections: “About us”, “Guarantees”, “Payment and delivery”. It is very good if the website has a “Guarantees” section.

2. If, after reading all the information, you can evaluate it as plausible, then pay attention to whether the site has technical support. If there is one, then talk to the consultants and ask them in more detail: what delivery times they guarantee, how long they have been working in this area, and whether there is a possibility of exchange or return of the purchase.

3. After this, it’s time to move on to the next stage: try to find real reviews about this store on the Internet. It would also be a good idea to check whether the store is on the list of unreliable sellers. Single list on this moment does not exist, but many resources have lists of dishonest stores. Lists of unscrupulous traders are regularly updated.

Lots of reviews and the whole story can only be found in an online store that has been operating for quite a long time. And if you see a young site, and it already has a lot of rave reviews, then this looks alarming.

How to check the reality of the site's origin

In an attempt to sell their products, many sellers do their best to disguise their store as European or American. However, this information is quite easy to verify. To do this, you need to find relevant information about the owner of the site and its location. Arranging such a check will not cost you anything.

This technology gained rapid development when the markets computer technology Laptops were gaining popularity. The fact is that a laptop is first and foremost mobile computer. Accordingly, it cannot be connected by any wires. The laptop must access the Internet via a Wi-Fi receiver, which was implemented in last years.

Ping- the time spent receiving packets from your computer to the Server on the Internet and back. Acceptable broadband connection quality should be less than 100 ms.
Jitter- The result of calculating the difference when measuring successive pings. Ideal network characterized by - 0 ms. In a real network, the ping difference is greater than zero.

YOUR GRADE and LINE QUALITY

Internet network quality classification:

A - Great. MOS is greater than 4.37. Ping below 50ms and 0% packet loss
B - Okay. MOS from 4.28 to 4.37. Ping below 90ms and 0% packet loss. Network quality is not suitable for all online games.
C - Satisfactory. MOS from 4.00 to 4.37. Ping below 150ms and 1% packet loss. Poor for online games and Internet telephony; for streaming video, the quality of the Internet is acceptable.
D - Unsatisfactory. MOS from 2.50 to 3.99. Ping below 300ms and 3% packet loss. In such a network, all Internet applications will work poorly.
F - Very bad. MOS is less than 2.50. Ping below 500ms and 20% packet loss. You should contact your provider to resolve the problem.
