Your guideto the Internet

Short, easy to say, no hyphens or digits. For Russia — .ru or .рф, worldwide — .com. Check availability in the form above, register it to yourself or your company and turn on auto-renewal so the domain never lapses.

DNS is the Internet’s “address book”: it links your site name to a server and mail. To make a domain work, set the hosting NS servers at the registrar. Changes spread from a few minutes up to a day.

Hosting is space on a shared server: cheap and simple for sites and shops. A VPS is a virtual server with its own resources and settings. A dedicated server is a whole machine for heavy loads and special needs.

It is the share of time your site is available. 99.99% means no more than about 4–5 minutes of downtime a month. For a business, customers almost never see an error instead of your site.

A builder is a quick start for a simple site. A CMS is a flexible site or shop you update yourself in a control panel. Custom is for your own design, integrations and ongoing support.

We copy files and the database to the new hosting, test it on a temporary address and only then change DNS. Keep the old hosting until the change has spread. Full guide in “How to move a site?”.

A certificate encrypts data between visitor and site and shows the browser padlock. Without it browsers show warnings and search engines rank the site lower. It has to be renewed on time.

Files and database — daily; keep several copies, including off the main server. Once a month check that the site really restores from a backup.

It answers customers 24/7 from your prices and terms, suggests products, takes requests and hands complex questions to a manager. Works on your site and in messengers.

An agent not only answers but acts: creates CRM deals, books clients, checks order status. It gets minimal permissions and a human approves important steps.

Ads bring requests right away while the budget runs. SEO takes longer but brings search customers continuously. Best results come together: ads at launch, SEO and useful content for the long run.

An address like info@company.ru earns more trust than a free mailbox and stays with the company when staff change. Set up SPF, DKIM and DMARC records for reliable delivery.
