Including meta name=”robots” content=”follow” Has no Impact on Search as it is the Default Value
Using meta name=”robots” content=”follow” has no impact on search as this is the default value and Google essentially ignores it. Apart from adding a very minimal amount of additional HTML to the page, there is no value in removing it apart from avoiding running into the same question again in the future.
Using Noindex Header Tag Will Not Prevent Google From Viewing a Page
Including a ‘noindex X-Robots-Tag’ HTTP header directive on a sitemap file will not affect how Google is able to process the file. You can also include this directive on other documents such as CSS files, as it will not affect how Google views them, instead it will just prevent them from showing up in a web search.

Website Owners Don’t Need to Specify What Google Should & Shouldn’t Render
Website owners don’t need to implement anything on their sites that would tell Google what is unnecessary to render, as it should be Google’s job to figure this out. Being selective and not rendering particular elements can also cause problems for a website.
Use X-Robots-Tag HTTP Header to Noindex Indexed Sitemap Files
If sitemap files are indexed for normal search queries, then you can use the X-Robots-Tag HTTP header to noindex all pages ending in .xml or .gz.
JavaScript Snippets Can Close Head & Cause Elements Below to be Overlooked
Be careful when adding JavaScript snippets to the head of a page, as this might cause the head to close prematurely and cause elements like hreflang links not to be processed, as they are seen as part of the body.
Google Only Accepts Rel Alternate Links in Head Section
Google doesn’t accept rel alternate links returned in the response header, they are only accepted in the head section of a page.
Google Uses Semantic Markup to Understand Importance of Highlighted Text
