If you look around, not only within WA, you see many complaints about the monster called Google. But I feel we are unfair. Just see what we have from it:
- Google Analytics Tool - free of charge.
- Search Console (Webmaster) - again free of charge.
- Fetch option within the Webmaster as something really special.
- Many other free tools.
A bit more about Fetch. When you publish a post, you use this tool to let Google know about it. They take a note, and sometimes this happens instantly. My fastest documented example is 8 seconds; this is how quickly I was able to check the post's ranking. In practice it was instant.
So just think about this simple fact. The post is made available to the audience instantly and globally. If you are selling or promoting some stuff, this means you can have traffic and make sales instantly.
Which other business would provide you something like this, and which other tool? I remember one sentence from a Google's representative "it is not you and Google, we are on the same side". I think we should realize this.
For those who do not use Fetch, it is in Webmaster, see the screenshot. It is not compulsory to use it, but it speeds up the process. It can take weeks before the post is ranked without it.
But ranking in Google is so hard? Yes indeed, but this is not because of Google, it is due to many others who are trying the same as you.
