Improving your website doesn’t have to be difficult. 

All you need is the right software. To identify and rectify any issues that might be affecting your site’s search engine optimization (SEO)—the actions you’re taking to improve your visibility in search results—user experience, accessibility, and conversion rates.

We’ve hand-picked 12 website optimization tools to help you unlock your website’s full potential. 

Let’s dive in.

1. Site Audit 

Site Audit is a website crawler tool that assesses your site’s overall health.

It performs over 140 technical SEO (activities that improve a website for search engines and users) and on-page SEO (actions on your webpages that improve search rankings) checks to identify issues on your site.

These issues can affect your site’s crawlability (meaning how easy it is for search engine bots called crawlers to access and index your content), rankings in search engines, and more. 

The tool also provides recommendations on how to address each issue you come across. 

To use Site Audit, open the tool to set up a project. Then, click “Start Site Audit.” 

Once the audit is done, head to the “Overview” tab to see a high-level look at your website’s overall health. Including a Site Health score (between 0% and 100%) that can help you understand how well your site is doing from an SEO perspective. 

Next, click the “Issues” tab. 

The most severe issues, (called “Errors”) appear at the top of the list in red. These are the issues that have the greatest impact on your SEO, user experience, and website performance. So fix them before moving on to “Warnings” and “Notices.”

You can also click “Why and how to fix” next to any issue to see suggestions for fixing it. 

And you can even measure your success after fixing the issues. Simply re-run the audit and head to the “Progress” tab.

• Largest Contentful Paint (LCP): This measures how long it takes for the largest content element on your website to load. Ideally, important parts of your website should appear quickly for visitors.
• First Input Delay (FID): This measures interactivity(i.e., how long the browser takes to respond when someone first clicks, taps, or scrolls on the webpage). A slow response might cause visitors to leave your website. 
• Cumulative Layout Shift (CLS): This measures visual stability (i.e., whether elements like images or videos move around unexpectedly as the page loads). Good visual stability makes it easier for people to read and interact with your website.
