After a while, Google will know about your pages, and keep the ones it deems ‘useful’ – pages with original content, or pages with a lot of links to them. The rest will be de-indexed. Be careful – too many low-quality pages on your site will impact your overall site performance in Google. Google is on record talking about good and bad ratios of quality content to low-quality content.

I think ranking in organic listings is a lot about trusted links making trusted pages rank, making trusted links making trusted pages rank ad nauseam for various keywords. Some pages can pass trust to another site; some pages cannot. Some links can. Some cannot. Some links are trusted enough to pass ranking signals to another page. Some are not. YOU NEED LINKS FROM TRUSTED PAGES IF YOU WANT TO RANK AND AVOID PENALTIES & FILTERS.
When referring to the homepage, a trailing slash after the hostname is optional since it leads to the same content ("" is the same as ""). For the path and filename, a trailing slash would be seen as a different URL (signaling either a file or a directory), for example, "" is not the same as "".
We’ve used other tools in the past, but SE Ranking offers more up-to-date data and information, which benefits our agency and clients. SE Ranking allows us to access historical data with just a few clicks without ever having to leave the interface. From daily ranking updates to current search volume trends, there are numerous aspects that are essential when formulating client strategies, and with SE Ranking’s continuously updated system we are able to use this data to help our clients succeed.

For instance, in a recent test (2019), if you have a page title longer than 12 words, all the keywords beyond 12 words evaporated from the page copy. This is a change from the way Google used to work, when the extra words were included as part of the page copy, not just part of the title. So, if you have a 15 word title, the last 3 words will not count towards ranking, if that test result was to be replicated.
All sites have a home or "root" page, which is usually the most frequented page on the site and the starting place of navigation for many visitors. Unless your site has only a handful of pages, you should think about how visitors will go from a general page (your root page) to a page containing more specific content. Do you have enough pages around a specific topic area that it would make sense to create a page describing these related pages (for example, root page -> related topic listing -> specific topic)? Do you have hundreds of different products that need to be classified under multiple category and subcategory pages?
Another illicit practice is to place "doorway" pages loaded with keywords on the client's site somewhere. The SEO promises this will make the page more relevant for more queries. This is inherently false since individual pages are rarely relevant for a wide range of keywords. More insidious, however, is that these doorway pages often contain hidden links to the SEO's other clients as well. Such doorway pages drain away the link popularity of a site and route it to the SEO and its other clients, which may include sites with unsavory or illegal content.
