Use the SEO List Crawler to quickly perform a SEO check on a list of URLs. You can enter up to a whopping 1000 URLs at a time with a daily limit of 2000 URLs . After submitting your list the tool will automatically extract important On-Page SEO elements. The returned results can be used to perform a technical SEO audit or generate a SEO report by using the Excel export function.
It’s important to know if a page / URL returns the right status code. Some status codes you can expect when entering an URL:
When the spider detects a 301 or 302 status code it will also detect the final destination URL (the URL where visitors and spiders are redirected to). The destination URL is only visible in the Excel export to save some valuable space inside the HTML data table.
The SEO List Crawler will first check if the Page Title can be found if this is the case it will extract the content and it will perform a character count to see it stays within the max. visible (55 – 65 character) limit.
The meta description is extracted to check if a description has been added to the page and to check the character length of the content. To make sure your description is completely visible in the search results limit it to 150 / 160 characters.
The H1 Heading tag is extracted and displayed when found. The spider will also check how many H1 are found on a single page.
The link count number represents the total links found on a page (internal + external links). If you need a specified report please use this tool to get more detailed report: http://www.seoreviewtools.com/internal-link-analyzer/
When a canonical tag is found on a page it will be returned in the report and you can see which page should be index by search engines based on the canonical location.
The final metric returned by this tool (when found), is the Twitter Profile URL. This isn’t a On-Page SEO element, but it’s just nice information to have when you are looking for ways to contact the web master or author of an article.
