I will share some tips to get more value in your Google search when researching in order to write about something. These tips are not new and I am sure most of the people already know them, but it is very helpful for Internet beginners.

Exact words

If you want Google to search for your words exactly as you have written them then put your words between quotation marks:

“like this”

Similar words

If you are interested in a topic, then you can tell Google to look for similar words too adding a tilde before the word:

~like this

You get that symbol  by pushing shift + ` in an English keyboard.

Search in a specific website

This option is really useful when you need to have an idea about how other posts about the same subject look in the place where you are about tu publish. Do it

site:thesite.com

Or you can focus in a specific type of webs:

site:org

site:com

site:es

Type of file

Yes, it is also possible! Are you looking for a pdf?

filetype:pdf

other example: filetype:docx

Remove searches with a specific word

Sometimes there is another topic that uses  the same words, but are not related with yours. For example, if you look information about the fruit apple you could try

-software -hardware -computer

And you will remove all the sites with these words.

These are the most basic tools Google offers you, and they are very useful in some researches.
