In the case of putting a new site online or creating a new page, indexing by robots can take several days, so you will need to be patient before you get alarmed.
Tip 1: If, after more than a week, you notice that your site is still not indexed, you can submit its URL manually on the Google Search Console, but don’t insist on doing so, once will be enough because google doesn’t like to feel forced.
Tip 2: To find out if your site is present in search engine results, type a query in the search bar of your browser: site:domainname.lu (without https:// and without www.) and check that the different pages and subpages of your site have been indexed.
Tip 3: If you want to increase the indexing speed of your website, create a sitemap and add it to your robots.txt file or send it directly to the Google Search Console. The online service xml-sitemaps.com offers a free basic version that can help you create your sitemap. However, for complex and voluminous sites, it is better not to do without professional advice.
The tools offered by your favorite search engine will be very useful to you, do not hesitate to check the Search Console regularly to make sure that everything is going well on your site and that Googlebot is able to index your content.
