Complete redesign of website and 301 redirects

[seoanalytics]

I did a complete redesign and content change for my website.

I have my new webpages indexed but they still haven't replaced the old ones after 1 month. In search results I see both the old ones and the news ones.

How long of a delay should I expect (approximately) for the old pages to be replaced by the new ones knowing the entire website was changed.

Thank you,

The answer here depends upon the strength and visibility of your site.  Strong sites convert in a couple weeks.  Weak sites can take a month or more to convert.

For at least the past three to six months, Google has been really slow with this type of work.  The times that I mention above are more historic than what is happening today.

Is a domain authority of 25 with a page authority of 18 considered strong (meaning a couple of week to get the page ranked) ? Or Should I be looking at 1 month or more like 2 to 3 months or more you think ?

Does the fact that my entire website was updated slow dow the process also ?

I would expect that a site with domain authority of 25 could take a month or more to change.

Presently, I see 404 pages on Amazon taking a month to drop from the SERPs and redirects on a DA 70 taking a few weeks to fully switch.

I see patience is the key here !

Should I use https://support.google.com/domains/answer/4522141?hl=en to do the redirect and maybe speed it up  or is a redirect file my htaccess ok and won't change anything

I never use more than a 301 redirect.

Perhaps using Google's suggested methods will cut the wait.  I try to conserve on labor,

Did you leave the old sitemaps (xml and html) up until Google got all your new pages indexed?

My understanding (could be wrong) is that leaving the old sitemaps provides a simple way for Google to keep seeing that "oldpage.html" is redirected to "newpage.html".

The more often Google sees the redirect, the faster they index properly. And an easy way to make sure they keep seeing the change is to leave your old sitemaps up for awhile.

Not I didn't leave the old sitemap.
