Welcome to the Q&A Forum

Sitemap looks fine. Click on the urls in GSC and see the referring links. That would give you some more insight.

Sounds like a forum script would work for you.

He also mentioned 500 backlinks to the Facebook page, which I will assume aren't crappy. If they are legit, I would try to avoid changing the Facebook URL. Maybe you create a separate FB page and outreach to the webmasters and ask them to update the URL (or better yet, link back to your website instead). Later on, you can merge the two pages.

Create question "category" pages that groups up multiple answers into larger, more encompassing pages.

amazon, zappos, walmart, microsoft store - many ecommerce sites don't use tabs.

A common workaround seems to be to have "tabbed navigation" but instead of toggling visibility, it scrolls down to the corresponding section.

Agreed with one note... its a really bad idea if you are already ranking for the terms you like to. There will definitely be a period of time where you will lose your rankings and although they should return to their previous rankings, Google is fickle.

So if you aren't ranking in the top 50 for several terms, simply changing the URL won't get you to the first page (it may get you into the top 50 though). You would need to update the content and backlinks (internal + external) to see worthwhile movement. Otherwise you just risk losing ranking for the terms you currently do well for.

Sound like you want a "Flowerpedia Mexico" and a "Flowerpedia USA" (with different content on each) website that you want to offer in both languages (MX in Eng/Spa & USA in Eng/Spa).

If that's correct, what you have seems fine, as long as you are consistent throughout. Just be sure to set the language + country in your hreflang markup for each.

My guess it's a http(s) and www/nonwww issue. e.g. you have the www version in GSC which contains a sitemap that has non-www urls and you force remove www on the actual web pages (so the non-www pages are indexed, but the www. version of the site you are looking at in GSC isn't)

Make sure all of these are consistent.

Ah, I see now.

This looks like a prev/next orientation + it contains the actual text "ARTIKEL 9 VON 14".

My best guess would be that google is picking up on that (either naturally or through their data highlighter tool).

Not much unfortunately. Just make sure the website is as secure as possible as hacked pages usually do more damage than bad links.

If you continue to build quality content and links, the effects of the spammy backlinks will continue to diminish (until as some point, you will be considered an authority and negative SEO won't really work any longer). But until then, staying up to date on incoming backlinks and updating the disavow file is your best bet.

General consensus is that it is still usually indexed/ranked but the value is diminished (and they may be going in the direction of completely ignoring it). See this post: https://www.seroundtable.com/google-hidden-tab-content-seo-19489.html

Artikel = items

This is a results of there being multiple schema offers (see the example with Dell UltraSharp 30" LCD Monitor) on the page that are marked up.  Google reads this and displays the # of offers and their min-max price range (if set) in the serps.

You can post to reddit without using imgur. Instead, post it on your website along with supplementary content, make sure the page loads fast and isn't spammy, and post that to reddit instead.

Imgur is it's own separate entity that people browse through. The main advantage imgur has is that images are "more compatible" with reddit (in terms of plugins that make loading an image easier, people are more likely to click/view because they know its a good experience).

Go to http://analytics.moz.com/pro > the rightmost column = "Insights", click on the one that corresponds > here you get a list of all of Moz's insights.. look for a section called "Keyword opportunities"

I've used http://cuterank.net/ (desktop application) before with success. It uses your own IP so if you need to check lots of keywords/locations, you may need proxies.

Hmm, not that I'm aware of. If anything, Google used to scrape Yelp reviews. Where are you seeing that this is the case?

Google's official recommendation is just to unblock js/css and let it figure it out since it's smart enough now. I personally like to give as many suggestions/clues to follow as possible so that it doesn't get confused.

IMO, the onclick/href hybrid is probably the best for user experience. With proper canonicals set up (so that Google only indexes 1 version and avoids any duplicates), it's also my suggested method for SEO.

My guess is the apostrophe (') in the meta description that is causing the issue. Check out your other pages that don't have the meta description indexed.

What does your robots.txt file contain? (or share the link)

Try removing it, clearing server cache and fetching as google again.

Essentially, you should have the AJAX load "onclick" but have the "href" link to the hardlink for people who don't have JS enabled (and crawlers).
