For one thing, without content, SEOs would have nothing to optimize for search engines. The metadata they add to posts is an attempt to help robots like Google and Facebook wrap their digital heads around the complexities of the content they're indexing. Every link earned by every marketer points to a piece of content, and the keywords that people type into search engines are an attempt to find—yep—content.
From top to bottom, on-page content and its metadata should be optimized to inform search engines as simply as possible why each page of your site exists and what you are hoping users get from it. And as algorithms evolve to understand human search behavior, they become smarter at ranking content in search engine results pages (SERPs) in a way that serves users the best content every time.
What would be the purpose of/reason for moving back to a different url? If its been a few years, I’d leave it alone unless you watched everything decline since moving to the main url. Moving the forum to a new url now would probably be a bit chaotic, not only for your main url but for the forum itself…. Only reason I could imagine myself moving the forum in this scenario would be if all those links were really awful and unrelated to the url it currently sits on…
It doesn’t make any sense to optimize for words that people don’t use. Good keyword research makes sure that you use the same words as your target audience and this makes the whole effort of optimizing your website far more worthwhile. In addition, by looking at search intent, you find out which questions your customer has. Those questions should get an answer in the form of quality content.
When a company is secure in their local market, they can then consider expansion and better face the challenges that accompany expanding into the international market. These challenges range from product or service alterations that may be necessitated due to import/export technicalities. Language barriers that may arise when promoting or branding beyond the local market.
Unlike other forms of online marketing, content marketing relies on anticipating and meeting an existing customer need for information, as opposed to creating demand for a new need. As James O'Brien of Contently wrote on Mashable, "The idea central to content marketing is that a brand must give something valuable to get something valuable in return. Instead of the commercial, be the show. Instead of the banner ad, be the feature story." Content marketing requires continuous delivery of large amounts of content, preferably within a content marketing strategy.
