Hello there
1. First of all, place your main keyword at the beginning: Search engines assign more importance to the first word in the title tag than to the second one and so forth. From a usability perspective, since users understand just the first 11 characters of links, then it is important to make the most out of these characters by placing the most important content there.
2. And remember, don't put your company name on every single website page. The problem with this is that when Google comes along to index your site, it has no idea what your site is about, so it looks in the HTML for clues. One place it looks is in the page title, which is what you see in your tag on your browser. If you keep using your company name over and over again, you end up indexing your company name a lot in Google's search engine. This is great you say...so when someone Googles "My Company Name" I will be first. That's true, you will be. But unless you are Nike or Coke, you don't have massive brand recognition, so while you may get a bit of traffic from your name, you are missing out on people looking for your services. So my final advice here is put your company name on your home page only along with your industry and use the other pages for more product related keywords.
Mmm sorry no study here but reading a lot and watching some guru videos from time to time!!
Hope this helps!
