You will find a simple IF Statement that returns an error if a specific file is not found in the tk or tcl directory. You can comment the IF Statement as provided below and try running your PyInstaller code once again.

#if not os.path.isdir(tcldir):
    #raise FileNotFoundError('Tcl data directory "%s" not found.' % (tcldir))

From 1 Order a week, to 3 Orders a day with Google AdWords

In 2016, I started my own Resume Writing Service as a part-time venture. I went at it with a lot of thought. Built a professional website, wrote appealing content and published several blogs. But that wasn’t enough to get the phones ringing. I was receiving an average 1 order per week through SEO and about 2-3 orders per week through word-of-mouth and other sources. Well, that does not sound much of a business, does it?

It was time to get back to the drawing board. It was not my business that was the problem. It was just my marketing strategy that needed a rethink. With my small business idea, spending heavily on marketing would be foolish. I had to choose a Paid advertising medium that was smart.

Google AdWords was my preferred Paid advertising choice and within a few weeks of research my ads were live on Google.

With just USD 100 per month on Google AdWords, I was able to generate an approximate 3 orders per day with a phenomenal Click-Through-Rate of 8 to 10%.

The average Click-Through-Rate of Google AdWords is about 2%. Anything above 2% is considered above average CTR.

With a successful Google AdWords Campaign, I was able to keep my Marketing Budget to below 2% of the Revenue Share. The recommended digital marketing budget for most companies my size is anywhere between 5% to 8%.

If you are wondering why I chose Google AdWords, and not Facebook, Instagram or other mediums. Well, I will leave that for another blog post.
