Yeah, that’s a pretty common situation, so don’t stress too much 🙂
Most of those “indexing” and “crawl” errors look scary, but a lot of them aren’t actually critical. First thing I usually do is check which pages are really affected — sometimes it’s just old URLs, duplicates, or pages that aren’t meant to be indexed anyway.
If you’re not a coder, you can still fix a lot: make sure important pages return 200 (not 404), remove or redirect broken links, update your sitemap, and resubmit it in Search Console. Also check robots.txt and noindex tags — sometimes pages are blocked by accident.
Honestly, Google Search Console gives pretty clear hints if you open each issue and read the details. Just go one by one, don’t try to fix everything at once.
And from experience — these errors don’t always kill your traffic unless they affect key pages, so focus on the important stuff first 👍
