Webmaster Guide: Pre-Launch Checks for a New Site

Webmaster guide readers preparing to launch a new site should first check the domain redirect, HTTPS, robots.txt, sitemap, access to essential pages, and form functionality. Performing these checks in the same environment, saving the existing settings first, and retesting the same URL after every change helps identify visibility and access problems early.

Define your access scope first for a webmaster guide

Before starting, clarify which layer you can access. If you use shared hosting, the hosting panel, domain DNS management, and the site's content management panel may be sufficient. On a managed server, you may need administrator access to the web server configuration and application logs. You should also have access to property management in the relevant webmaster tool for search engine verification.

Before changing the settings of a live site, make copies of the DNS records, existing redirects, robots.txt content, and, if applicable, SEO plugin settings, or record their values somewhere secure. Change only one factor at a time. This allows you to understand which change was ineffective if the problem is not resolved and which step should be reversed if a new problem appears.

Five-step technical pre-launch check

1. Test the domain and HTTPS redirects. In a browser, open both the root domain and the www or non-www version in use. If both versions go to the expected primary address and the connection appears secure in the browser, the basic redirect is appropriate. If one version does not open, goes to the wrong site, or creates a redirect loop, first compare the DNS records with the domain mapping in the hosting panel. If the DNS is correct but the loop continues, adjust the application's URL settings and the server-side HTTPS redirect so that they point to the same destination; do not disable security checks.
2. Open the home page, important content, and error pages. Using the menu visitors will use, go to the home page, a content page, the contact page, and, if applicable, a product or service page. Each page should open with the expected content and an appropriate status code. If a link returns a 404, first check whether the URL matches the actual permalink in the content management panel; if the content was moved, define an appropriate redirect rather than deleting files at random. If only one page is affected, correcting that page's link is safer than changing the settings for the entire site.
3. Review robots.txt and page indexing settings. Add the robots.txt path to the end of the domain and check that the file can be read. The file must not accidentally block areas of the live site that need to be crawled. Also review the noindex setting in the page source or SEO plugin for the home page and important content. For example, if the new site was protected with noindex during preparation, remove only this setting once the launch decision is final; do not change the access policy for the administration panel and draft areas.
4. Verify that the sitemap is actually accessible. Open the sitemap address generated by the SEO plugin or application in a browser. If the file is empty, contains only drafts, or returns a 404, check the content publication status, site URL, and plugin generation settings. A valid sitemap should show the URLs intended for publication; it should not list administration screens or areas requiring special access. After fixing the sitemap, open the same address again and check the current content list.
5. Test forms and the basic user flow. Submit a valid test entry through the contact or registration form, then check for the expected confirmation message on screen and the message in the recipient's inbox. If the form returns an error, first review required-field validation, the recipient address, and the new entry in the application logs. If the issue concerns registration authorization or SMTP configuration, correct only the relevant setting; do not write passwords or access tokens to logs or a publicly accessible area.

How should you interpret a finding?

If HTTPS works but only one domain version goes to the wrong address, the problem is generally in the DNS or canonical redirect layer rather than the content; do not change content settings. Conversely, if the home page opens correctly but an important page returns a 404, examine that page's permalink and any migration redirect instead of changing the domain.

If the search engine tool reports that it could not discover the page, first distinguish a robots.txt block from a noindex tag. If robots.txt is blocking it, narrow the scope of the crawl rule; if noindex is present, correct the page-level indexing option. If the sitemap can be read but a single URL still does not appear, check whether the URL is actually published, accessible through links, and available without requiring a login. A positive result from one check does not prove that the other layers are also correct.

Renew the evidence after a change

For example, suppose hypothetically that the home page of a new promotional site opens but the search engine tool cannot crawl the URL. If you find a block in robots.txt covering the entire site, edit only the rule required for the live content and preserve the original file. Then reopen the same URL that caused the earlier problem, submit a new crawl request, and review the new crawl result from after the time of the change. If it still appears blocked, check the noindex setting separately; do not assume that the initial finding explained the entire cause.

Connect the launch decision to a measurable result

An acceptable result at the end of the check is that the preferred domain opens over HTTPS, the main user flows do not return errors, important URLs do not produce 404 responses, robots.txt and noindex settings match their intended purpose, and the sitemap shows current URLs. If the form test fails, correct the submission configuration connected to the form before announcing the site. However, if the expectation is only search engine visibility, do not treat immediate indexing as the sole measure of launch success; first verify that the page is crawlable and accessible.

If the same problem continues after a setting change and new evidence points to a different layer, reverse the change and restore the original value. Do not make bulk changes, especially to DNS, redirect, and indexing settings. Before launching the site, you can also review the relevant resources on İyibirNet and compare the verification options provided by your hosting panel according to your environment.
