Use the primary keyword in the meta title. Meta titles are headlines that appear with results on a search page. Include the primary keyword in this title as it helps crawlers understand the page, but more importantly because it helps searchers find relevant results on SERPs. Keep your title to 65 characters or less so the full headline is visible in results. Also, include the primary term as close to the front of the title as possible to help catch extra attention.
The toolset is written in C# and requires the .NET Framework to run. However, this only applies to the toolset itself. The installation packages you create with the toolset do not require any extra framework or software to be installed on the target computer. Similarly, there might be a few additional utilities required for some special applications (merge modules, patches) but only on your build computer, the client will only need the finished and self-contained installer package, nothing else.
Using long tail keywords is now a waste of time. This is because of Google RankBrain. RankBrain is an AI (artificial intelligence), so to this new algorithm, all related long tail keywords are the same. It is now pointless to use such long tail keywords. What I would recommend, instead, is use Medium Tail Keywords along with LSI Keywords. This is the new way of keyword research! 😉
