SVG elements are allowed to have <title> elements contained within them, and this shouldn't be considered an SEO violation when embedded into an HTML page.

There should be different content on URLs with and without slashes. Although this should be OK with search engines (don't leave it to chance) it is bad convention and could confuse users. URL's with a trailing slash typically denote a directory.

To test whether common homepage URL's are accessible with the same content being served as the naked domain (actual homepage) will help to determine whether the web server serves duplicate content on different URL's.

Some common ones include:

• index.php
• home.php
• default.php
• index.html
• home.html
• default.html
• index.aspx
• home.aspx
• default.aspx

Although we do not believe in the necessity of a sitemap.xml file we do believe that if you have one it should be valid. If /sitemap.xml returns 200 we should parse it to make sure its valid.

Each page should have an h1 tag as the main heading. Subsequent h1 tags must be within a sectioning root or content sectioning tags.

A edit was suggested from the library page - https://passmarked.com/library/content/seo/title.length.

The documentation of the rule should be in docs/title.length.md

The suggested content is:

Your HTML5 document title defined in `<title></title>` tags will show up in SERPs (Search Engine Result Pages). If they are too long, they will be truncated and will not behave as you intended. They might be truncated missing out on important keywords but mostly they will just look weird and cause humans not to click on them.

If your titles are less than 55 characters it should display correctly in SERP's most of the time.

How do I fix this ?

Make sure that your titles do not exceed 55 characters. You might have to ease on your keyword use and keep only the most relevant. Use Passmarked to check this for you :)

There should be a redirect or no page served when connecting to the IP address of the server where the site is served from. Duplicate content is bad.
