Crawlability and Architecture
First and foremost, your website has to be crawlable before you can begin to think about SEO. To foster easier navigation for search crawlers, the website’s structure should be clean and well-organized. In order to make your structure as clean as possible, some of the main focus areas will be your sitemap, robots.txt file, and your internal links and URL structure. Site Audit covers over 20 of the most important common issues in this area.
On Page SEO
Issues regarding your content, title tags, h1 tags, meta descriptions, and images all play into your website’s on page SEO. In order to optimize, you’ll want to avoid any duplicate content, titles, descriptions or h1 tags. You’ll also need to make sure that your content, titles, and descriptions are all at an optimal length. Site Audit checks for over a dozen of the most common on-page SEO issues, so you can identify all of the mistakes on your site that could be hurting you.
A great deal of SEO depends on technical aspects of a website such as proper HTML, page load speed, and mobile optimization. Site Audit will tell you if you have any pages with an oversized HTML file or slow load speeds. It will also point out the use of flash, frames, or other outdated technology that should be avoided for SEO.
When moving a website from HTTP to HTTPS there are a lot of common mistakes that you can run into. From proper certificates to redirects and canonicals, encryption and more, Site Audit checks for every possible issue involved when a website moves to HTTPS. There’s a dedicated report showing all of your HTTPS-related issues which you can get to quickly by following the widget from the Overview report.
For larger companies and global websites, international SEO can be tricky.

Site Audit checks for multiple issues like the use of the right language and country codes, conflicts with page source code, incorrect hreflang links, and more.
