Before you scrape your old website, make sure to analyze the performance of your current website, so you can make the right strategic decisions.
Everyone has an opinion of how a website should look like (which is not a bad thing), however, decisions should be based on data. For example, you can take a look at your web analytics tool (e.g. Google Analytics) and analyze your performance metrics. Are visitors engaging with your website the way you want them to? Do they spend enough time on your website, do they click on your call-to-action buttons? Can you spot which pages have the highest bounce rate? What about conversion rate? Google Analytics and other web analytics tools can give you plenty of actionable data about the performance of your website.
Other tools, such as Hotjar, can help you see how visitors are really using your website by visually representing clicks on a page, scrolling behavior, mouse hover, and you can even watch recordings of your actual visitors on your website.
In short, make sure you base your decisions on data and your target audience, this way you will get the best return on your investment.
