Here is how to add title tag in WordPress easily without using editing codes.
The title tag is extremely important for visitors to see on search engine result page (SERP). It should clearly describe what the content is about, and the search engine algorithm definitely takes it into account.
Adding title tag for a page in WordPress can be done by editing the HTML code as follows:

<title> XYZ </title>
An experienced SEO person can view the source code of a page to detect if the title tag is missing or not.
Most WordPress themes can automatically add the title to the header with the name of the website, but there is an easier way with a plugin without scanning through clustered HTML codes.
Some times editing title tag and forgetting syntax can break the website, and it takes a lot of work to locate the problem in the HTML code.
Using a plugin like Yoast SEO makes it so much easier without making coding mistakes.
