Separate domains may also be used for different brands, regions, or products. Sometimes the reason is simpler: the same content needs to appear under different addresses for different audiences.\n\nThe articles themselves may be identical.\n\nCreating a separate channel for every domain quickly leads to duplicate content. A new article has to be published several times, corrections copied manually, translations checked separately, and someone has to remember which version was updated where.\n\nPublicasta lets you connect several domains to a single channel.\n\nArticles, translations, comments, and channel settings remain shared. The domains only determine where readers enter the channel and which language version should be shown first.\n\n## Publish Once, Use Several Domains\n\nSuppose your articles are available in English, Spanish, and German.\n\nYou could connect three domains to the same channel:\n\n- `www.example.com`\n- `www.example.es`\n- `www.example.de`\n\nThere is no need to create three separate channels.\n\nYou publish the article once and add English, Spanish, and German versions to that same article. They remain part of one publication and are managed inside one channel.\n\nEach domain can have its own default language.\n\nA reader visiting the Spanish domain will first be shown the Spanish version, if it exists. The German domain can prefer German, while the international domain can default to English.\n\nThe channel itself remains the same.\n\nWhen you publish another article, you do not have to copy it to three different places. A new translation is added to the existing article rather than becoming another independent publication.\n\n## One Main Domain — or Several Working Mirrors\n\nOne connected domain is selected as the primary domain.\n\nOther domains can either redirect to it or work as mirrors.\n\nWith a redirect, visitors are sent to the primary or canonical domain.\n\nA mirror behaves differently. The reader stays on the domain they originally opened.\n\nFor example, someone may visit:\n\n`www.example.de/getting-started`\n\nand continue browsing articles on `www.example.de`.\n\nThe same domain is also preserved in channel and article URLs, as well as RSS, JSON, and Markdown links.\n\nThis makes a mirror more than another address pointing to the same destination. It becomes a separate entry point into the same channel.\n\n## Let Each Domain Speak to Its Own Audience\n\nA domain often already tells you something about the audience.\n\nFor example:\n\n`www.example.com` — English\n`www.example.es` — Spanish\n`www.example.de` — German\n\nEach mirror can have its own default language.\n\nIf the URL does not specify a language explicitly, Publicasta first tries the language assigned to that domain. If that translation does not exist, the normal channel fallback languages are used.\n\nThe Spanish domain can open Spanish versions by default, while the German domain opens German versions, without splitting the articles into separate channels.\n\nThis works well for projects that already have regional websites and want to keep familiar local addresses without maintaining duplicate content.\n\n## Readers Are Not Locked to the Domain Language\n\nThe domain only sets the default.\n\nIf the reader chooses another language or opens a URL with an explicit language parameter, that choice takes priority.\n\nAll translations still belong to the same article. The domain simply helps decide which one to show first.\n\n## Keep Internal Links on the Current Domain\n\nArticles often link to other articles in the same channel.\n\nIf every link contains a full URL, those links become tied to one particular domain.\n\nFor internal navigation, you can use a relative URL:\n\n`./getting-started`\n\nA reader on the Spanish mirror will open the next article on the Spanish domain.\n\nA reader on the German mirror will stay on the German domain.\n\nThe same article content can therefore work across all mirrors without maintaining separate sets of links for each site.\n\n## Where This Becomes Especially Useful: Documentation\n\nA regular blog or publication can use multiple domains to separate audiences without duplicating articles.\n\nThe same setup is particularly useful for documentation, help centers, and knowledge bases.\n\nThese channels usually contain many interconnected articles, and their structure often needs to stay identical across several languages or websites.\n\nFor example, the same documentation channel could be available through:\n\n`docs.example.com`\n`ayuda.example.es`\n`hilfe.example.de`\n\nThe articles and translations remain in one channel. The Spanish address opens Spanish versions by default, the German address opens German versions, and the documentation itself is still maintained in one place.\n\nFor larger documentation channels, you can create a dedicated contents article and pin it.\n\nFor example:\n\n- Getting Started\n- Account Settings\n- Working with Articles\n- Integrations\n- API\n- FAQ\n\nRelative links work well here too.\n\nA pinned article can also be used as the navigation structure for the whole channel. H2 and H3 headings form sections and nested items.\n\nOnly published articles from that channel are included. External links, duplicates, and the pinned article itself are excluded.\n\nWhen a reader opens the documentation through a mirror, navigation links keep the current domain. The reader’s language is also preserved unless the source link specifies another language explicitly.\n\nLong articles can have their own table of contents based on H2 and H3 headings in the selected language version.\n\nOn wide screens, navigation can move into a side panel after scrolling. On narrow screens, it appears in a compact bar at the top. If both article navigation and channel navigation are available, the reader can switch between them.\n\n## What Search Engines See\n\nThe same article appearing on several domains needs clear canonical and language signals.\n\nPublicasta assigns one canonical domain to each published language.\n\nThe `canonical` URL points to the main address for that language version, while `hreflang` connects the different translations.\n\nEach mirror sitemap contains only the canonical URLs assigned to that domain.\n\nAdding several mirrors does not mean that the same article has to be indexed as several unrelated publications.\n\nFor Google Search Console, each mirror should be added as a separate property and managed by the domain owner.\n\n## One Article, Shared Reader Activity\n\nA custom domain does not create a separate copy of the channel or a separate set of reader data.\n\nComments, reactions, favorites, and subscriptions belong to the same publication regardless of which active domain the reader used.\n\nReaders can sign in to their Publicasta account from the primary domain or any active mirror and continue using those features.\n\nThe sign-in screen identifies Publicasta because reader accounts are handled by the platform. A custom domain changes the public address of the channel, but it does not turn Publicasta into a white-label service.\n\n## See Which Domain Brings the Traffic\n\nPublicasta records the domain through which a page was opened.\n\nAnalytics can therefore separate traffic from:\n\n`www.example.com`\n`www.example.es`\n`www.example.de`\n\nThere is no need to create several channels just to compare traffic from different domains.\n\n## Connecting a Custom Domain\n\nOnly the channel owner can connect a domain.\n\nEnter the domain in channel settings and Publicasta will provide a TXT record to verify ownership.\n\nOnce verified, point the domain with a CNAME record to:\n\n`connect.publicasta.com`\n\nFor a root domain, use CNAME flattening, ALIAS, or ANAME if your DNS provider supports it.\n\nDNS changes may take some time to propagate. Publicasta automatically rechecks domains that are still pending, and you can also start a manual check from channel settings.\n\nAfter Cloudflare validates the hostname and issues an SSL certificate, the domain can be selected as primary or switched to mirror mode.\n\nIf your DNS configuration includes CAA records, they must allow the certificate authority used by Cloudflare.\n\nIf your subscription no longer includes custom domains, the interface shows a grace period before the domain is disconnected. Articles are not deleted and remain available through their Publicasta addresses.\n\n## One Publication, Several Ways In\n\nA single channel can serve several websites, regions, or language audiences.\n\nIt may be a blog, a company publication, a collection of articles, a help center, or a multilingual knowledge base.\n\nThe articles and their translations stay in one place. Each domain gives readers a different way into the same channel and can open the language intended for that audience by default.\n\nA new article only needs to be published once. Its translations can be added to the same publication, while domains and languages are configured around it without creating duplicate copies of the content.","available_translations":[{"language":"ar","title":"قناة واحدة ونطاقات متعددة: انشر مرة واحدة واصل إلى جماهير
