Does Google Adwords helps in improving Organic Search Engine Rankings in Google?

Answer is NO.

Google Adwords is a Paid Advertising that offers instant traffic whereas Organic Listings is Zero cost advertising that helps in driving relevant traffic. Both are totally different and work independently from each other.

In order to receive high rankings in Google, it depends upon several factors like Google PR, back links, title & meta tags, indexing frequency, keyword density, prominence & proximity, website popularity etc. Google uses its special secret formula using these factors to display its Search Engine Result Pages (SERPs) based on keywords or keyphrases keyed in. It keeps on updating its formula & parameters that affects search engine listings from time to time. Also, more and more websites are adding globally, which leads to increase in competition level.

On the other hand, Google Adwords can be designed to keywords, location, audience & budget specific. It definitely helps in driving most relevant & traffic over organic listings. But it has no connection with search engine ranking factors that Google follows for organic listings.
