Technical audit is an integral part of website search engine optimization. It is a process of examining website pages and detecting issues that may hinder a domain from ranking highly in organic search.

With the Site Audit in Serpstat, you can find website aspects requiring attention and fixing to improve rankings and user experience. Besides, this tool allows you to evaluate the results of the SEO work carried out since the results are compared to previous scans.

Benefits of a Technical SEO Audit

Performing an SEO audit and checking if the site complies with search engine requirements is a must for website owners and their SEO specialists.

Often, people start considering a website audit in case of an emergency, such as a Google penalty. It can cause a significant drop in rankings for the targeted keywords or even get your website wholly excluded from search results. Sounds like an SEO nightmare, right?

That's where a thorough audit of website is vital, allowing you to detect and fix technical SEO issues. After implementing the improvements, you can start monitoring your performance in organic search results and, after a while, get it back to normal.

However, you need an SEO audit even when everything is fine with the site: traffic is growing, and positions are gradually increasing. You can further speed up the growth of the website by identifying and correcting technical issues.

Performing a detailed site check before starting the work on the site's SEO helps to find minor issues and severe problems so that the optimizer can safely work on other ranking factors and promote the site.

Here's a short list of what you'll achieve by performing site audits and fixing discovered issues:

1.compliance with the search engine requirements;
2.better user experience;
3.lowered bounce rate;
4.increased traffic;
5.boosted rankings;
6.improved web performance; security.

Advanced settings

After you finish setting up the Site Audit project, click the "Start" button for your first SEO audit scan.

You will see the SDO in the project dashboard when the audit is complete. Domain Optimization (SDO) demonstrates the level of domain optimization from 1 to 100. It is calculated based on the ratio of the number of issues and their severity to the total number of possible domain issues. The higher the SDO, the better optimized the site is.

SDO score in My projects

The storage period for detailed project data is limited to a period of 2 to 100 months depending on your plan, and then the data will be deleted.

If more than 2 months have passed since the last date of the audit, detailed information of the issues and URLs, where they were found, will be deleted. There will be available only the SDO and the number of issues.

To save your data:
1) export the needed reports and download them;
2) increase the storage period of your data by upgrading your pricing plan.

Go to the "Audit summary" of the "Site audit" tool to get more detailed information about the results and stages of the audit.

Audit Summary

During and after crawling, you'll see logs of the performed audit process.

If 0 pages are scanned and indicators read "N/A", check the logs to see the reason for the failed scan.

Logs of Site Audit

When the audit is done, you will see a graph of the SDO domain score dynamics from the first scan to the latest.

Issues overview

Further, there's a table with a short list of vulnerabilities found on the site.

All issues and recommendations

All issues

The "All issues" report presents a detailed list of issues found on the website and recommendations on how to fix them.

The list is divided into logical blocks according to types of issues.

To get a detailed explanation and advice for fixing, click on the issue. The report presents:

How to fix a status code

Response codes

HTTP status codes are responses that the server delivers upon the user's request. Errors 4xx and 5xx negatively affect the website ranking — the search engine likely considers the site unreliable, unavailable, or abandoned and stops it from indexing.

It's essential for webmasters and SEOs to monitor all server responses and find pages with errors.

Serpstat finds pages that send the following response codes:

HTTP status code issue

Meta tags

Title is a title of a page that should concisely and accurately describe the content of the page (up to 70 characters).

Description is a meta tag containing a more detailed page description (from 100 to 300 characters).

This metadata affects the site's ranking and participates in the formation of snippets — the site's description on the SERP. Make sure the meta tags are complete, their content is unique, and are within an appropriate length.

Serpstat checks meta tags for the following issues:

duplicate or missing meta tags


H1-H6 headers are a significant ranking factor. Headings are used to structure the content of the page; each heading indicates the importance of the text that follows it.

You must keep the heading sequence from H1 to H6.

The H1 tag is the most significant headline; further are subheadings with H6 as the least significant. Each page must have one H1 heading, and the heading text must be unique within the site.

Serpstat checks headers for three important issues:

missing or multiple headings

Content and multimedia

Serpstat examines content and multimedia for elements that violate search engine requirements.

The tool checks the presence of the following content errors:

Lorem Ipsum is a nonsense text that developers use to fill in page layouts. If it is present on a site page, the search engine may perceive it as irrelevant.

The body is the content on the page. It is important for search engines as an indicator of page usefulness. The absence of text in the tag negatively affects the ranking.

lorem ipsum issue

Multimedia elements are also essential for optimization. Although they don't directly affect the ranking, they can cause bad user signals and indexing errors. In addition, pictures also affect the loading time of the website.

The tool checks the presence of the following multimedia errors:

Page indexing and accessibility

Page Indexing is the process during which the search engine collects information about your website. The search bot scans (crawls) the pages of your domain and all its elements and stores the collected data in its index.

As Google puts it: "The Google index is similar to an index in a library, which lists information about all the books the library has available. However, instead of books, the Google index lists all of the webpages that Google knows about".

For a search robot to index a page, it must be open for indexing. Serpstat checks the site for the following issues:

Issues with indexing


Redirects are a way to send users and search robots to a URL that differs from the one they initially landed on. They are typically used when a domain name has changed, a website page is deleted, or when switching to the secure HTTPS protocol.

Serpstat shows if website pages have 301 or 302 redirect:

redirects issues


It is essential to correctly configure links on the website because they are a significant factor in its authority and ranking in search results. The quality of the domain link mass affects its position in the search results.

Serpstat checks links for the following issues:

issues with links

Server parameters

Incorrect server parameters may lead to a traffic drop and site indexing issues since users and search engine bots would not be able to access the website.

Serpstat checks the site for the following issues:

wrong server parameters

HTTPS certificate

Having an HTTPS certificate is a crucial authority factor, as ensuring the users' data is secure is the basic standard everyone should meet nowadays.
Also, Google ranks such websites higher in search results.

Serpstat checks the site for the following issues:

problems with https certificate

Hreflang attributes

If your site contains language versions of the content, use the "hreflang" attributes to indicate this to the search engine. This attribute helps the search engine determine what language you're using on a specific page and display it to the corresponding target audience in search results.

Serpstat checks the site for the following issues:

hreflang attribute

AMP-related issues

AMP (Accelerated Mobile Pages) stands for Accelerated Mobile Pages. Sites using AMP load faster on mobile devices and rank first in mobile search results.

It is recommended to use AMP technologies to improve the loading time. Inferior, generated content is one of the most common reasons for the deterioration of ranking positions. Consider these aspects in the optimization to avoid the most common mistakes.

AMP technologies

Markup-related issues

Open Graph and Twitter Card markups are used to create an informative and presentable preview of your site on social networks and Twitter.

Micro-markup helps the search engine generate special snippets and recognize page content. It shows crawlers that text or other page elements are important and belong to a specific data type.

Serpstat looks for the following markups in the code:


PageSpeed for Mobile and Desktop

Website page loading speed is an important ranking factor. Fast and proper loading increases the overall website usability, improves your rankings, and drives more traffic to your website. Poor loading speed affects user behavior: slow-loading websites tend to annoy users, which increases the bounce rate, making your search engine rankings drop.

Serpstat identifies loading speed issues and offers fixes for both desktop and mobile versions of the site. Data is taken from Google PageSpeed ​​Insights tool.

Some of the parameters of the issue are:
