Have you seen an increase in blocking based on language requesting?

Hello how i can add these:
metatags = soup.find_all('meta',attrs={'name':'generator'})

When i try to use it for the keyword "Commbank" i get this error:
'NoneType' object has no attribute 'get_text'

On line 36 don't you want to include the link in the dictionary you append to found_results?

@rajrsingh Thanks for pointing this out. I have made the changes.

@cabbage-dealer The code on the blog was updated to fix this error. This happens when a result doesn't have a standard description. I have also updated the code to avoid this issue.

I keep getting all elements printed as in reversed (link ,description, title, tank, keyword) instead of (keyword, rank, title, description, link), sometimes it's not on order. I Google this and it's because the elements are contained in a set, rather than a list.
Is there a solution to print out elements in specific order?

How can i get results for different countries?

@EdmundMartin

Google has updated it's selectors, you just need to change this selector a bit.

@EdmundMartin thanks for this. I am getting the result returning [] still. I see you mentioned that Google has updated it's selectors. What have they updated to?

I am very new to this, programming and all, but I like the idea of this project and I am trying to expand on it. Anyways, when I ran this the first time, it worked. However, running it multiple times gave me the response that I've been blocked by google. Is that because I need to use Google's API to scrap a search? Thanks for your help!
