Question on Google Crawl Statistics .
Are there any rules for scanning an online store?
How many scanned pages per day should an online store have with the following indicators:
Online store of furniture and armchairs (5 years).
In total, there are 8,000 pages in the Google index.
In Search Console 2000 pages are crawled every day, that is 20%.
Commodity - 6000 pages. The rest is categories and a blog, which adds 2 pages per day.
Q: Is the crawl budget too low?
Can you recommend something to increase it?

Answer 1

I can advise you to set the last-modified header, if it is set correctly, the date the page was created or the date it was last modified will be stored there. In the presence of such a header, the following will happen:
1. The load on the server will decrease and the performance of the site will increase.
2. When scanning the site, the search engine will see which pages have changed and will not load too much, which means it will have more time to crawl exactly those that need it.
You can also set up a sitemap, which will also improve the indexing speed (of course, with the right settings)
