Submit your content to search engines

Regardless of whether you have the best contents or not, if people can't find them, then they are useless. Install XML sitemap module. It will make it easier for search engines to crawl your website and keep their results up to date. The sitemap created by this module can be automatically submitted to Ask, Google, Bing and Yahoo! search engines.

Search engine optimization(SEO)

Now that your contents can be found, make sure that search engines know how to read and rank your contents.

• Pathauto will automatically convert URL path to human readable path. Instead of showing something like /node/123, it will show something like /article/my-favorite-fruits. This will increase the likelihood for someone to click on your link from the search results. The more your links get clicks, the better they are ranked.
• Using Redirect in conjunction with Pathauto will ensure that if your URL path changes, it will still redirect to the correct path. It will prevent visitors from receiving page not found error(404 Error).
