Welcome to the Q&A Forum

Assuming Google translate is mostly correct, it looks like you've really over optimized this page with keyword phrases. I'm all for including keywords a couple to a few times within your content but it needs to be written for a human with search engines in mind not the other way around. I found that you have the exact phrase, "Furniture moving companies in Jordan" 15 times within the content on this page and the phrase, "in Jordan", 60 times because you include it after every mention of "furniture transport companies", "furniture transfer companies" and a few other variations. This seems like overkill. After cleaning up your content, I'd suggest getting more links to your site from relevant content as every site that wants to rank needs to do this. Good luck.

If you Care about the Search Console Error ONLY It just means Google has decided to index some URLs which do not appear in here: http://www.servicesarab.com/sitemap_index.xml so add them or don't, it really doesn't matter that much and it is extremely unlikely to change your SEO performance much at all If you are Really Concerned about SEO Performance personally I think that this is quite telling: https://analytics.moz.com/pro/link-explorer/spam-score?site=servicesarab.com&target=domain According to Moz, 45% of the domains in their index which share similar features to yours, have apparently been banned or penalised by Google (not really good) You site has (according to Ahrefs): https://ahrefs.com/site-explorer/overview/v2/subdomains/recent?target=servicesarab.com 18,840 backlinks from 242 referring domains. That's a pretty crazy balance, not very diverse at all https://d.pr/i/0ROVCA.png (screenshot) It seems like end of 2017 / beginning of 2018, tons of links for the site were produced in a very artificial and obvious way In the end, old SEO tactics that try and trick Google into thinking your site is great, are not very useful in 2018/2019 It's doubtful that there is a strong technical-SEO reason for the site's problems. It is more likely that Google is just restoring your site to 'where it should be' in the rankings It seems as if the usage of older SEO techniques tricked Google for a little while: https://d.pr/i/tsiXrh.png - but in the end, the unsustainable approach was not good enough
