Welcome to the Q&A Forum

Hi romaro, From my understanding, using these tags as part of a mobile XML sitemap is not necessary and in fact, Google don't recommend having a separate mobile sitemap: https://www.seroundtable.com/google-mobile-sitemaps-20137.html Instead, for a dynamically served site, the important things are: Use the Vary HTTP header to signal your changes depending on the user-agent. Detect user-agent strings correctly. You can read more about Google's guidelines for dynamic serving here: https://developers.google.com/search/mobile-sites/mobile-seo/dynamic-serving

Gracias Bridget!

Another good job Alan.

If you put a rel canonical in the other pages, you will be telling the search engines that the other pages are duplicate. i think you are better of not doing so, for the sake of the other pages. The test is, after you remove the duplicate content, any paid ads what is left on a page, is enoutth to justify the page as a usefull page. Keep to this rule and you will be OK

Hi, 1. It would make the most sense to optimize for the singular and plural forms of a keyword on the same page. For example, if you're targeting the phrases, "green car" and "green cars," you should optimize a single landing page for both terms. Although Google shows different results for plurals, it is still aware that they're variations of the same word. I would not recommend creating separate landing pages for singular/plural of the same word. 2. This is a strategy that most likely will not help you. If your search results pages show excerpts of the content of each page being shown in the results, all the content on those pages will be duplicate content. You don't want to cannibalize the SEO you've done on the actual pages of your site by having Google crawl excerpts of that content as well. Though, there may be a way to pull this off to your benefit if you somehow show unique content on those search results pages. But unless they're long-tails, you're not likely to rank those search result pages above website that are actually optimized for the same keywords.

First of all, good luck with your new website!  Now onto your questions: I wouldn't suggest taking on every imaginable category of news, instead I would focus on one topic. Your sitemap should only links to pages on your website, however the pages should (and most likely must) present the source of the original news article. Yes. For text a regular sitemap will work, for video check out video sitemaps, and I am not too sure about podcasts, maybe someone else will be able to chime in on that.
