10 Tactics To Perform An On-Page SEO Audit

Now that you have free tools to help with your on-page SEO checklist. Let’s dive into the 10 tactics you can use to perform an effective SEO check for your website.

1. Run a Site Crawl

A “crawl” is when software runs through your website to find SEO problems. Running a site crawl is also the first step of any SEO on-page audit, using a tool like SEMrush Site Audit or Ahrefs Webmaster Tools


To run a site crawl, enter your website’s domain name or URL into the tool and start the process. Depending on the size and complexity of your site, the crawl may take a few minutes to a few hours to complete. 

Once the crawl is done, you will get a report with various metrics and issues you must address.

2. Check Your Organic Traffic

The next step of your SEO site audit is to check your organic traffic. Google Search Console or Bing Webmaster Tools will help you in this step. 

Organic traffic is one of the most critical indicators of your site’s SEO performance. It reflects how well your site ranks and attracts visitors to your target keywords and topics. Checking this index measures your SEO efforts’ effectiveness and finds any improvement areas.


Use the performance report in on-page SEO audit tools to review your organic traffic. Then, filter by date range, device type, country, etc. You will see various metrics for your site and individual pages, including impressions, clicks, CTRs, average positions, etc.

3. Check for Any Duplicates of Your Site

After checking your organic traffic, it’s time to find duplicates of your site. This step improves SEO and ensures the best user experience. Further, it helps your site avoid penalties from search engines for duplicate content. 

To check for duplicates on your site, you can use SEO optimizers like Google Search Console, Ahrefs, SEMrush, or Copyscape. They will provide insights into pages with similar content or content that appears elsewhere on the web.

Also, check different URLs on your site and ensure each page has unique and original content. 


When you have similar or identical content on multiple pages, use canonical tags (rel=canonical) to mark the preferred page version. It helps search engines understand which version to index and rank.

4. Find Indexing Issues

While doing on-page SEO audit, finding indexing issues involves checking if search engines are properly indexing your web pages. To do this, access Google Search Console and navigate to the “Index” tab to review the index status.

Another way is to visit Google and type “” (replace “” with your actual domain) to see which pages from your site are indexed by Google. If crucial pages are missing, there might be indexing issues.


There are many ways to handle indexing issues, which the most common is hiring an SEO company. We recommend ROI Digitally – one of the best Michigan SEO companies. They offer full-funnel digital marketing services, including on-page SEO audits. Contact them to identify SEO issues of your site and take action to improve its performance.

5. Ensure Your Site Is Mobile-Friendly

Ensuring your site is easy to use on mobile devices is vital to bringing visitors a great user experience. First, open your website on a smartphone or tablet to see how it looks and works. Check if it’s easy to navigate, read content, and interact with buttons and links.

Then, enter your website’s URL into Google’s Mobile-Friendly Test tool. It will tell you if your site is mobile-friendly and highlight any issues. Other helpful on-page SEO audit tools are Google PageSpeed Insights or GTmetrix to check your website’s load speed on mobile devices.

6. Benchmark Your Core Web Vitals Scores

Core Web Vitals are scales Google uses to weigh how good a website feels for users. They measure how fast a page loads, how quickly visitors can interact with it, and how steady things stay while loading.


In 2022, John Mueller from Google confirmed they now only use Core Web Vitals to judge websites, not the older speed signals they used. He also stated that these metrics affect how Google ranks a website.

The main things to check and compare are:

  • Largest Contentful Paint (LCP)
  • First Input Delay
  • Cumulative Layout Shift (CLS) 

To monitor these metrics, use the Core Web Vitals report in Google Search Console. Also, check out the Performance report in Ahrefs’ Site Audit for more detailed data.

7. Reclaim Authority by Fixing Broken Pages

The next step in the SEO page audit is reclaiming authority by fixing broken pages. Broken pages, or 404 error pages, harm user experience and negatively affect your website’s search engine rankings. They make users wasting time to find the information they’re looking for. 

We have Google Search Console, website crawlers, and online broken link checkers to detect broken pages. They will analyze and help you find out the issue.


Suppose a page was moved or had a new URL, set up 301 redirects from the old URL to the new one. Consider creating a similar version if the page no longer exists. Further, create a custom 404 error page with helpful information to guide users when they meet a broken link.

8. Check for Sitemap Issues

A sitemap is a list of pages you want search engines to check out. You should avoid putting redirects, non-canonical pages, or pages that no longer work on this list because it may confuse Google. Ensure the essential pages you want Google to notice are in your sitemap.

To keep an eye on any sitemap problems, just visit Google Search Console and click on “Sitemaps.” 

9. Find Declining Content

Search rankings don’t remain forever. When content becomes outdated, its search traffic drops off. Therefore, boosting it by updating and republishing the content is also a crucial step in on-page audit.


Here’s a simple way to find out whether the content is losing its visibility using Google Search Console:

  • Step 1: Go to the Search results report.
Step 1: Go to the Search results report.
  • Step 2: Set the date filter to compare the last 6 months with the previous period.
Step 2: Set the date filter to compare the last 6 months with the previous period.
Step 2: Set the date filter to compare the last 6 months with the previous period.
  • Step 3: Click on the “Pages” tab.
Step 3: Click on the "Pages" tab.
  • Step 4: Arrange the table based on the “Clicks Difference” from low to high.
Step 4: Arrange the table based on the "Clicks Difference" from low to high.

10. Review Content Gaps

Content gaps happen when your competitors rank for keywords that you don’t. It can be time-consuming to figure out these keywords manually. Therefore, to quickly find content gaps, you can outsource SEO services. Otherwise, use Ahrefs’ Content Gap tool and follow these steps:

  • Step 1: Put your domain into Ahrefs’ Site Explorer.
  • Step 2: Open the Content Gap report.
  • Step 3: Input your competitors’ domains.
  • Step 4: Click on “Show keywords.” You’ll get a list of keywords your competitors rank for that you don’t.

And that’s also the final step of an effective SEO on-page audit. Improve your website today, so more people can find and enjoy what you offer online!
