See if he'll let you do a 2 month  test with a different home page and let him see the difference in the traffic/business and then let him make a more informed decision.

On  the other hand, the page that all your "home" navigation links go to should be a page like the one you wish your home page would be--a page with a bit more static content than the /начало/ page and one that other parties might link to instead of the domain's (current) default page. Develop your external links to that page.

In the market you're working in, you better have real, link-worthy, thought leadership-type blog posts regardless of what's on your homepage because it's likely that the majority of your search traffic will land on your blog posts--at least until you build awareness and strength for your brand. Don't blame the lack of traffic on the boss' decision on the home page if you haven't pushed really hard for top quality content. If you've done that and he/she hasn't complied, blame the lack of traffic on their business sense, not necessarily on the web site.

I wouldn't buy just for any SEO value a direct match .pw domain might have 'cause it won't have much. If you're buying it for your main site, because it matches your company name, you're still better off going with a dot com or dot net. unless, maybe, you live there--which apparently only about 21K people do.

Yes, this can be confusing when you're first starting out.

A keyword is a word or a phrase that your target audience would use when they perform a query in a search engine for a product or service, etc. For example, if the target audience for a particular landing page is a professional plumber, the copy on your landing page might really focus in on "40" linear shower drain" because a plumber might know to search for that right off the bat.  However, if the target audience for a landing page is a DIY'er who is researching how to build a shower pan for the first time, their initial searches may revolve around simply "shower drain". While both "40" linear shower drain" and "shower drain" may be considered potential keywords for your overall web marketing plan, you might only focus on one of those for any particular piece of web content,  while the other would not be considered a keyword for that page.

The reason different web pages might be crafted to target these individual terms is that the more specific a page can be in tailoring content to a certain keyword, the better able it is to compete with strong competitors who are also targeting that key phrase. If your page uses terminology that broadly applies to both audiences, Google is less likely to rank your page higher than a competitor page that focuses granularly on only one of them when that's what the searcher queries.

Simple, huh!

I know, not really. : )
