Meta tags are used to provide search engines with additional information about a page. Meta tags are added to <head> section of the HTML page. Meta description tag provides a short description of the page. In some situations this description is used as a part of the snippet shown in the search results for your website. Good description together with title increases CTR for your site and drives more organic traffic. That's why it is important to work on good page description.

Warning: Missing ALT Attribute

The alt attribute provides alternative information for an image if a user for some reason cannot view it (because of slow connection, an error in the src attribute, or if the user uses a screen reader). It also helps crawlers understand what is in an image. Providing meaningful description for an image also can help drive organic traffic from image search.

Notice: Page Size is Too Big

Speed is the critical quality parameter for users and thus for search engines. Faster pages have lower bounce rate and higher rankings in search engines. Though there is no ideal standard page size we recommend it to be within 51200 bytes. How did we come up with this number? Users now more and more tend to be on mobile device. Average mobile device uses 3G connection. 3G connection speed varies between 144 and 400 kilobit per second. To satisfy and impress a user with speed HTML page and blocking referenced resources should load within couple of seconds. We set limit to 500ms and this gives us the size of 51200 bytes on average connection. Moreover if you check your page with google speed test tool it will complain about slow website if your server respond longer than 200ms.

PageDetails
https://www.ted.com/read/ted-books Current: 61255 bytes, recommended: 51200 bytes
https://www.ted.com/topics Current: 127093 bytes, recommended: 51200 bytes
https://www.ted.com/talks Current: 84696 bytes, recommended: 51200 bytes
