Continuous Web Page Monitoring

Google Lighthouse is an excellent tool for improving the quality of web pages. During the development of a web page, you can run Google Lighthouse audit from your local machine and identify issues that are affecting the performance, SEO, accessibility for your web page.

Once the issues are identified, you can fix the issues based on the opportunities provided by Google Lighthouse audit. Your web page then goes live and everything is great, until the next set of changes need to be done to the web page.

The next set of the changes may again affect the page quality. If you are spending time and money to drive traffic to your web page, a web page with poor quality (performance, SEO) essentially translates to losing money.

DevRaven can help with automated continuous monitoring of your web pages and sends alerts when your web pages are poorly performing.
