Welcome to the Q&A Forum

You have to understand your audience requirements and then plan to write articles in your blog in such a way that your articles solve the purpose of your customer. Always remember "Content is the king".

You can get DA 25 plus without even earning backlinks, just write high-quality original content in your blog. (Disable right click throughout the site to prevent plagiarism)

At the initial stage, keep your topic very narrow. Getting DA does not solve our purpose. The articles should do sales for you which should be your ultimate goal. Have promotional banners within articles to take the user to our plans page and then aim for conversion. (This varies as per your business niche)

If the domain is same you can do 301 redirect of top pages (old website) that ranks higher to the newer version of the web page.

Secondly, without affecting your ranking you can move your old website pages to a newer domain also. This works if you want to change domain without modifying the sitemap and individual URLs of your website.

Make sure you have the search console access (verified) to both the website domains, Back-up your website and database(s) to restore in case of any error. Launch the website in the new domain.

Do 301 redirect via your site’s .htaccess file (At the old website host). Use the code below

RewriteEngine on
RewriteCond %{HTTP_HOST} !^www.newerdomain.com
RewriteRule (.*) http://www.newerdomain.com/$1 [R=301,L]

Once this is done, then login to Google Search Console and go to the old domain settings icon. There will be an option called "Change of address" click it and select the new domain. Now go to the new domain property and add XML sitemaps to Google.

That's it!

It might work. Purchasing expired or old domains and redirecting them to build your link equity. This is a completely different scenario. However, if you look spammy and are doing this with a ton of old, expired domains, you are going to get nailed.

Secondly, earning 17 domain authority is not a difficult task. You can develop your new site easily till 20-25 DA. Growing above 25 DA requires more commitment.

As your website got ranked in top positions use subfolders, let's say for an example if your primary domain in English is abc.com then have subfolder like www.abc.com/de/

Avoid choosing subdomain, If you go for a subdomain, you will lose your current authority as Google assumes subdomains as a separate domain.

As you wish to develop your website for other language use properly translated content from the native speaker of the language and use it under subfolders. If you simply use any API to translate your content then you will hit by Google's Panda Update for having poor content quality.

Avoid creating a new domain, instead, book that domain and redirect to the subfolder version (www.abc.com/de/)

Hope this strategy helps you!

Thanks, I did it. How long do you think it will take for Google to take action against the web spammers? Any Idea!

Google Search Console UI has changed. Still, you can find search terms under "performance" section from the left end of your search console and select queries to view the keywords for which your website appeared.

You have to use 301 redirect. Read this link from Google Search Console help https://support.google.com/webmasters/answer/6073543?hl=en

you can preserve the "link juice" from SEO perspective if you use 301 redirect.

Keyword stuffing, particularly hidden keywords (1116 keywords) in all pages and unfortunately the website ranks 1-5 position in the first page of google

Like how we can "suggest an edit" in Google Business Listings, is there any way to report Google about the webmaster guidelines violation?
