Use sitemap files to help search engines index your site
One useful technique you can employ is to create a sitemap file for your web site.
A sitemap file is a text or XML file that lives in the root directory of your website. Search engine crawlers then look for this file, and use it as a source of interesting URLs to crawl on your site.
For example, a sitemap file for Web Envoy might look like this.
https://webenvoy.net/ https://webenvoy.net/features https://webenvoy.net/pricing https://webenvoy.net/frequently-asked-questions https://webenvoy.net/about-web-envoy https://webenvoy.net/register
In many cases you need to create the file yourself, and this allows you to curate the URLs that you include in the file.
Sometimes, for example with a WordPress installation, you can install a plugin that will automatically generate and update your sitemap file for you. The Yoast SEO plugin does this for you, and there are many others.
