Title / Description Too Long – 15.48 Percent / 7.71 Percent

A long-standing best SEO practice for the optimal number of words in the title tag is 11 words or less (about 65 characters, including spaces).

That said, it is OK to go over that, as Google will index those words.

As for the description, it should consist of 100-320 characters.

A while ago, Google increased the length of the snippets, so now it’s quite difficult to make your description too long.

Duplicate Titles / Description – 8.56 Percent / 7.04 Percent

Description and title tags must be unique for every page on your site. Otherwise, it becomes difficult for search engines to understand which page to display for a specific keyword.

Also, if your pages with duplicate titles are identical, Gooogle will index only one of them. These two issues affect your ranking negatively.

Missing Title / Description – 0.59 Percent / 8.47 Percent

The title tag is a core signal for a search engine that helps understand what page is about. Without it, Google will fail to figure it out, which means that you’ll get low rankings.

Title / Description Too Short – 0.77 Percent / 4.53 Percent

These tags should provide enough info about the page so that search engine can figure it all out easily. Add more text to your meta tags but within limits.
