I have submitted sitmap.xml. But Search Console shows errors in some pages like SiteMap submitted but not indexed? Please suggest some tricks

You can also use the Search Console Sitemaps API to manage your sitemaps. The API provides all the same functionality and information as this report.

f you've submitted your XML sitemap in Google Search Console, investigate what URLs Google's reporting to be missing and verify whether these need to be indexed. If they need to be indexed, add them to your XML sitemap. If they don't, make sure to implement a robot's noindex.

1. If you don't have a XML sitemap yet, create one now(opens in a new tab).

2. If you do have an XML sitemap, but you haven't submitted it yet in Google Search Console, do so now(opens in a new tab).

3. If you've submitted your XML sitemap in Google Search Console, investigate what URLs Google's reporting to be missing and verify whether these need to be indexed. If they need to be indexed, add them to your XML sitemap. If they don't, make sure to implement a robots noindex. If you really want to keep Google away from these URLs, then update your robots.txt.

f you've presented your XML sitemap in Google Search Control center, explore what URLs Google's answering to be missing and confirm whether these should be ordered. Assuming they should be ordered, add them to your XML sitemap. On the off chance that they don't, try to execute a robot's noindex.
