HTML Metatags
Title
Booking.com | Official site | The best hotels & accommodations
The title has an optimal length. Search engines typically displays the first 50–70 characters of a title tag. If you keep your titles under 70 characters, our research suggests that you can expect about 90% of your titles to display properly.
Description
Big savings on hotels in 120,000 destinations worldwide. Browse hotel reviews and find the guaranteed best price on hotels for all budgets.
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
Language not found
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.

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.

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
3.15 %
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.
