How to find low competition niches with good search volume?

So, when I gain a link I always check to see if the page that is linking is in the Google cache. I've noticed recently that more and more pages are actually not showing up in Google's cache, yet still appear in search results. I did read an article from someone whoo works at Google a few weeks back that there is sometimes an error with the cache and occasionally the cache will not display. This week, my own website isn't showing up in the cache yet I'm still ranking in SERP's. I'm not worried about it, mostly whitehat, but has there been any indication that Google are phasing out the ability to check cache's of websites?

I have been searching through these forums and haven't come across someone that faces the same issue I am. The folks on the Google forums are certain this is an algorithm issue, but I just can't see the logic in that because this appears to be an issue fairly unique to me. I'll take you through what I've gone through. Sorry for it being long. Website URL: https://fenixbazaar.com 1. In early February, I made the switch to https with some small hiccups. Overall however the move was smooth, had redirects all in place, sitemap, indexing was all fine. 2. One night, my organic traffic dropped by almost 100%. All of my top-ranking articles completely disappeared from rank. Top keyword searches were no longer yielding my best performing articles on the front page of results, nor on the last page of results. My pages were still being indexed, but keyword searches weren't delivering my pages in results. I went from 70-100 active users to 0. 3. The next morning, everything was fine. Traffic back up. Top keywords yielding results for my site on the front page. All was back to normal. Traffic shot up. Only problem was the same issue happened that night, and again for the next three nights. Up and down. 4. I had a developer and SEO guy look into my backend to make sure everything was okay. He said there were some redirection issues but nothing that would cause such a significant drop. No errors in Search Console. No warnings. 5. Eventually, the issue stopped and my traffic improved back to where it was. Then everything went great: the site was accepted into Google News, I installed AMP pages perfectly and my traffic boomed for almost 2 weeks. 6. At this point numerous issues with my host provider, price increases, and incredibly outdated cpanel forced me to change hosts. I did without any issues, although I lost a number of articles albeit low-traffic ones in the move. These now deliver 404s and are no longer indexed in the sitemap. 7. After the move there were a number of AMP errors, which I resolved and now I sit at 0 errors. Perfect...or so it seems. 8. Last week I applied for hsts preload and am awaiting submission. My site was in working order and appeared set to get submitted. I applied after I changed hosts. 9. The past 5 days or so has seen good traffic, fantastic traffic to my AMP pages, great Google News tracking, linking from high-authority sites. Good performance all round. 10. I wake up this morning to find 0 active people on my site. I do a Google search and notice my site isn't even the first result whenever I do an actual search for my name. The site doesn't even rank for its own name! My site is still indexed but search results do not yield results for my actual sites. Check Search Console and realised the sitemap had been "processed" yesterday with most pages indexed, which is weird because it was submitted and processed about a week earlier. I resubmitted the sitemap and it appears to have been processed and approved immediately. No changes to search results. 11. All top-ranking content that previously placed in carousal or "Top Stories" in Google News have gone. Top-ranking keywords no longer bring back results with my site: I went through the top 10 ranking keywords for my site, my pages don't appear anywhere in the results, going as far back as page 20 (last page). The pages are still indexed when I check, but simply don't appear in search results. It's happening all over again! Is this an issue any of you have heard of before? Where a site is still being indexed, but has been completely removed from search results, only to return within a few hours? Up and down? I suspect it may be a technical issue, first with the move to https, and now with changing hosts. The fact the sitemap says processed yesterday, suggests maybe it updated and removed the 404s (there were maybe 10), and now Google is attempting to reindexed? Could this be viable? The reason I am skeptical of it being an algorithm issue is because within a matter of hours my articles are ranking again for certain keywords. And this issue has only happened after a change to the site has been applied. Any feedback would be greatly appreciated 🙂

We have a travel website that has been ranked in Google for 12-14years. The site produces original images with branding on them and have been for years ranking well. There's been no site changes. We have a Moz spamscore 1/17 and Domain Authority 59. Sep 17th all our images just disappeared from Google Image Search. Even searching for our domain with keyword photo results in nothing. I've checked our Search console and no email from Google and I see no postings on Moz and others relating to search algo changes with Images. I'm at a loss here.. does anyone have some advice?

Google search results for a particular query was appearing in top 10 results but now the page appears but  only after clicking on the " omitted results by google." My website lists different businesses in a particular locality and sometimes results for different localities are same because we show results from nearby area if number of businesses in that locality (search by users) are less then 15. Will this be considered as "duplicate content"? If yes then what steps can be taken to resolve this issue?

I'm currently using the Yoast Local SEO plugin for WordPress to generate my KML file which is linked to from the GeoSitemap.  Check it out http://www.holycitycatering.com/sitemap_index.xml. A competitor of mine just told me that this isn't correct and that the link to the KML should be a downloadable file that's indexed in Google.  This is the opposite of what Yoast is saying...  "He's wrong. 🙂  And the KML isn't a file, it's being rendered. You wouldn't want it to be indexed anyway, you just want Google to find the information in there. What is the best way to create a KML?  Should it be indexed?

There is a plethora of choice today for aggregating customer reviews. BBB wants to collect ratings from our customers; there a commercial options that put me in more control; yelp wants to rate me locally.  Google... Given that I have some ability to steer customers toward my preferred review site, which one should I use?  From an SEO perspective, have you noticed whether some these sites carry more weight or credibility than others? I realize it may depend on the type of business we are. In this case I represent a software company and their customers are USA/global, rather than local.
