"Canonicals: Contains Fragment URL","Issue","High","1","0.010","Pages with a rel=""canonical"" that includes a fragment URL in the href attribute. Google generally doesn't support fragment URLs. These annotations are ignored and not used for canonicalisation by Google.","Remove fragment URLs from canonical annotations and ensure they are to accurate indexable pages to avoid them being ignored by search engines, and any potential indexing or ranking unpredictability.",""
"Directives: Nofollow","Warning","High","15","0.110","URLs containing a 'nofollow' directive in either a robots meta tag or X-Robots-Tag in the HTTP header. This is a 'hint' which tells the search engines not to follow any links on the page for crawling.

However, changing URLs is a big decision, and often it's not worth changing them for SEO purposes alone. If URLs are changed, then appropriate 301 redirects must be implemented.",""
"Links: Internal Nofollow Outlinks","Warning","Low","3","0.020","Pages that use rel=""nofollow"" on internal outlinks. Links with nofollow link attributes will generally not be followed by search engines. Remember that the linked pages may be found through other means, such as other followed links, or XML Sitemaps etc. Nofollow outlinks can be seen in the 'Outlinks' tab with the 'All Link Types' filter set to 'Hyperlinks', where the 'Follow' column is 'False'.

"H1: Multiple","Warning","Medium","3","0.020","Pages which have multiple <h1>s. While this is not strictly an issue because HTML5 standards allow multiple <h1>s on a page, there are some problems with this modern approach in terms of usability. It's advised to use heading rank (h1-h6) to convey document structure. The classic HTML4 standard defines there should only be a single <h1> per page, and this is still generally recommended for users and SEO.","Consider updating the HTML to include a single <h1> on each page, and utilising the full heading rank between (h2 - h6) for additional headings.",""
"Content: Low Content Pages","Opportunity","Medium","116","0.850","Pages with a word count that is below the default 200 words. The word count is based upon the content area settings used in the analysis which can be configured via 'Config > Content > Area'. There isn't a minimum word count for pages in reality, but the search engines do require descriptive text to understand the purpose of a page. This filter should only be used as a rough guide to help identify pages that might be improved by adding more descriptive content in the context of the website and page's purpose. Some websites, such as ecommerce, will naturally have lower word counts, which can be acceptable if a products details can be communicated efficiently.","Consider including additional descriptive content to help the user and search engines better understand the page.",""
"Page Titles: Duplicate","Opportunity","Medium","20","0.150","Pages which have duplicate page titles. It's really important to have distinct and unique page titles for every page. If every page has the same page title, then it can make it more challenging for users and the search engines to understand one page from another.","Update duplicate page titles as necessary, so each page contains a unique and descriptive title for users and search engines. If these are duplicate pages, then fix the duplicated pages by linking to a single version, and redirect or use canonicals where appropriate.",""
"URL: GA Tracking Parameters","Warning","Low","9","0.030","URLs that contain Google Analytics tracking parameters. In addition to creating duplicate pages that must be crawled, using tracking parameters on links internally can overwrite the original session data. utm= parameters strip the original source of traffic and starts a new session with the specified attributes. _ga= and _gl= parameters are used for cross-domain linking and identify a specific user, including this on links prevents a unique user ID from being assigned.","Remove the tracking parameters from links. Event Tracking is recommended in place of utm parameters for tracking additional interactions on a page such as downloads, link clicks, form submissions, and video plays.",""
"URL: Non ASCII Characters","Warning","Low","1","0.000","URLs with characters outside of the ASCII character-set. Standards outline that URLs can only be sent using the ASCII character-set and some users may have difficulty with subtleties of characters outside this range.","URLs should be converted into a valid ASCII format, by encoding links to the URL with safe characters (made up of % followed by two hexadecimal digits). Today browsers and the search engines are largely able to transform URLs accurately.",""
"JavaScript: Canonical Mismatch","Issue","High","2","0.010","Pages that contain a different canonical link in the raw HTML to the rendered HTML after JavaScript execution. Google can process canonicals in the rendered HTML after JavaScript has been processed, however conflicting rel=""canonical"" link tags may lead to unexpected results.","Ensure the correct canonical is in the raw HTML and rendered HTML to avoid conflicting signals to search engines.",""
"Response Codes: Internal Redirection (3xx)","Warning","Low","499","1.550","Internal URLs which redirect to another URL. These will include server-side redirects, such as 301 or 302 redirects (and more). View URLs that link to redirects using the lower 'inlinks' tab and export them in bulk via 'Bulk Export > Response Codes > Internal > Redirection (3xx) inlinks'.","Ideally all internal links would be to canonical resolving URLs, and avoid linking to URLs that redirect. This reduces latency of redirect hops for users, and enhanced efficiency for search engines.",""
"Images: Over 100 kB","Opportunity","Medium","1","8.330","Large images over a size threshold. Page speed is extremely important for users and SEO and often large resources such as images are one of the most common issues that slow down web pages. This filter simply acts as a general rule of thumb to help identify images that are fairly large in file size and may take longer to load. These should be considered for optimisation, alongside opportunities identified in the PageSpeed tab which uses the PSI API and Lighthouse to audit speed. This can help identify images that haven't been optimised in size, load offscreen, are unoptimised etc.","Uncompressed images bloat pages with unnecessary bytes, so ensure images are optimised with compression, properly scaled, and using the best image format to reduce file size where possible.",""
"Security: Missing Content-Security-Policy Header","Warning","Low","13808","49.690","URLs that are missing the Content-Security-Policy response header. This header allows a website to control which resources are loaded for a page. This policy can help guard against cross-site scripting (XSS) attacks that exploit the browser's trust of the content received from the server. The SEO Spider only checks for existence of the header, and does not interrogate the policies found within the header to determine whether they are well set-up for the website. This should be performed manually.","Set a strict Content-Security-Policy response header across all page to help mitigate cross site scripting (XSS) and data injection attacks.",""
"Page Titles: Over 60 Characters","Opportunity","Medium","3304","24.210","Pages which have page titles that exceed the configured limit. Characters over this limit might be truncated in Google's search results and carry less weight in scoring.","Write concise page titles to ensure important words are not truncated in the search results, not visible to users and potentially weighted less in scoring.",""
"Security: Unsafe Cross-Origin Links","Warning","Low","1426","5.130","URLs that link to external websites using the target=""_blank"" attribute (to open in a new tab), without using rel=""noopener"" (or rel=""noreferrer"") at the same time. Using target=""_blank"" alone leaves those pages exposed to both security and performance issues for some legacy browsers, which are estimated to be below 5% of market share. Setting target=""_blank"" on <a> elements implicitly provides the same rel behavior as setting rel=""noopener"" which does not set window.opener for most modern browsers, such as Chrome, Safari, Firefox and Edge.  The external links that contain the target=""_blank"" attribute by itself can be viewed in the 'outlinks' tab and 'target' column. They can be exported alongside the pages they are linked from via 'Bulk Export > Security > Unsafe Cross-Origin Links'.","Consider the benefits of including the rel=""noopener"" link attribute on any links that contain the target=""_blank"" attribute to avoid security and performance issues for the users of legacy browsers that may visit the website.",""
"H1: Missing","Issue","Medium","57","0.420","Pages which have a missing <h1>, the content is empty or has a whitespace.

"Meta Description: Over 985 Pixels","Opportunity","Low","3884","28.460","Pages which have meta descriptions over Google's estimated pixel length limit for snippets. Google snippet length is actually based upon pixels limits, rather than a character length.

"URL: Uppercase","Warning","Low","16","0.060","URLs that have uppercase characters within them. URLs are case sensitive, so as best practice generally URLs should be lowercase, to avoid any potential mix ups and duplicate URLs.","Ideally lowercase characters should be used for URLs only. However, changing URLs is a big decision, and often it's not worth changing them for SEO purposes alone. If URLs are changed, then appropriate 301 redirects must be implemented.",""
"Meta Description: Below 70 Characters","Opportunity","Low","401","2.940","Pages which have meta descriptions below the configured limit. This isn't strictly an issue, but an opportunity.

The page will still be crawled (to see the directive), but it will then be dropped from the index.","URLs with a 'noindex' should be reviewed carefully to ensure they are correct and shouldn't be indexed. If these pages should be indexed, then the 'noindex' directive should be removed.",""
"Page Titles: Same as H1","Opportunity","Low","12717","93.190","Page titles which match the h1 on the page exactly. This is not necessarily an issue, but may point to a potential opportunity to target alternative keywords, synonyms, or related key phrases.","This is not necessarily an issue, but may point to a potential opportunity to target alternative keywords, synonyms, or related key phrases.",""
"Meta Description: Duplicate","Opportunity","Low","4","0.030","Pages which have duplicate meta descriptions. It's really important to have distinct and unique meta descriptions that communicate the benefits and purpose of each page. If they are duplicate or irrelevant, then they will be ignored by search engines in their snippets.","Update duplicate meta descriptions as necessary, so important pages contain a unique and descriptive title for users and search engines. If these are duplicate pages, then fix the duplicated pages by linking to a single version, and redirect or use canonicals where appropriate.",""
"JavaScript: Meta Description Updated by JavaScript","Warning","Medium","2","0.010","Pages that have meta descriptions that are modified by JavaScript. This means the meta description in the raw HTML is different to the meta description in the rendered HTML.","While Google is able to render pages and see client-side only content, consider including important content server side in the raw HTML.",""
"Response Codes: External Blocked Resource","Warning","Medium","130","0.400","External resources (such as images, JavaScript and CSS) that are blocked from rendering by robots.txt or an error. This filter will only populate when JavaScript rendering is enabled (blocked resources will appear under 'Blocked by Robots.txt' in default 'text only' crawl mode). This can be an issue as the search engines might not be able to access critical resources to be able to render pages accurately. Blocked resources can be viewed by URL in the 'Rendered Page' tab, and any pages with blocked resources can be viewed under 'JavaScript > Pages with Blocked Resources'.","If critical to your content, update the external subdomains robots.txt and resolve any errors to allow resources to be crawled and used for rendering of the websites content.",""
"Meta Description: Missing","Opportunity","Low","1","0.010","Pages which have a missing meta description, the content is empty or has a whitespace. This is a missed opportunity to communicate the benefits of your product or service and influence click through rates for important URLs.","It's important to write unique and descriptive meta descriptions on key pages to communicate the purpose of the page to users, and entice them to click on your result over the competition. It can also mean Google use this description for snippets in the search results for some queries, rather than make up their own based upon the content of the page.",""
