HTML Metatags
Title
Wikipedia
The title is too short, it may not provide search engines and users with enough information to understand the relevancy of your page. You should try to keep the length of the title somewhere between at least 10 characters and 70 characters.
Description
Wikipedia is a free online encyclopedia, created and edited by volunteers around the world and hosted by the Wikimedia Foundation.
The description has optimal length. Keep in mind that the "optimal" length will vary depending on the situation, and your primary goal should be to provide value and drive clicks.
Encoding
UTF-8
You should always specify the encoding used for an HTML page. If you don't, you risk that characters in your content are incorrectly interpreted. This is not just an issue of human readability, increasingly machines need to understand your data too.
Language
Incorrect Language
Identifying the language of your content allows you to automatically do a number of things, from changing the look and behavior of a page, to assisting search engines in extracting information. If part of the page uses text in a different language, you can add a language attribute with a different value to the element that surrounds that content.
Language Region
Not Found
Images
Attribute ALT
Success, no any <img> without defined ALT attribute. Alt text is helpful to end users if they have images disabled or if the image does not properly load.
As a general rule, search engines do not interpret the content of image files. The text provided in the <img alt> attribute enables the site owner to provide relevant information to the search engine and to the end user.
H1-H6 Tags Information

For search engines, <H> tags helps understand the structure of the text on a page better. For users, headings are like anchors in a wall of text, navigating them through the page and making it easier to digest. The <h1> tag reinforces the core keyword(s) found in the <title>, <description>, and the <body>. We recommend that the <h1> tag includes keywords that reflect the contents of the page and that it is not longer than 150 characters in length, but don’t overuse the tags and the keywords in them. Keep it readable for users.

H1
1 H1 tag(s).
Your H1 introduces the topic your page is all about, just as a title tells a reader what a book is all about.
H2
5 H2 tag(s).
The H2s are akin to book chapters, describing the main topics you’ll cover in sections of the article.
H3
Subsequent headers, H3s to H6s, serve as additional sub-headings within each section, just as a book chapter may be split up by multiple sub-topics.
H4
H5
H6
Iframes Information
iFrame
iFrames not found.
Since search engines consider the content in iframes to belong to another website, the best you can hope for is no effect on SEO. Iframes tend to neither help nor hurt your search engine ranking. For this reason, it’s best to refrain from using iframes on main pages that you want to rank high in search engine results. Instead, fill high-priority pages with useful, unique content and save iframes for other pages.
Code To Text Ratio
Code To Text Ratio
5.91 %
A good code to text ratio is anywhere from 25 to 70 percent. This percentage refers to the visible text ratio, as opposed to HTML elements, image tags and other non-visible information. This has become especially apparent since search engines, such as Google, released the Panda update which placed importance on content-driven sites.
Favicons

Favicons are the little piece of graphic that represents your brand on browser tabs, bookmark lists, search history, search ads and even search results. These files are placed in a file called favicon.ico and placed in the root directory of a website. There are no direct SEO effects of having favicons. However, there may be indirect benefits such as increased usability of site and bookmarks. It makes your website look more professional and help a users to remember your site while browsing through multiple URLs. If you want to get mentioned benefits you have to specify icons for different web browsers and sometimes even for different mobiles.

Default Favicon
Line 15, /static/favicon/wikipedia.ico
Backup icon for most desktop browsers (if no icon of the right size is found). Tag format <link rel="shortcut icon" href="path-to-16x16-icon.ico" type="image/x-icon" />
16x16 Optional Favicon
