Should you invest your time and money in increasing the amount of traffic or the quality of traffic to your website?

I will answer this question for e-commerce business.

For an e-commerce business, the most coveted traffic is from people who buy the same thing that you sell from your COMPETITOR.

It is possible to get one 'Add to Cart' from visits from your Pinterest marketing, and it is also possible to get no 'Add to Cart' froms of visits from Reddit. I have tested both on my e-comm store, and both statements are true for a persona of mothers aged- in the USA.

Same goes for all other marketing efforts. When you start Facebook advertisements for your e-comm store, you will get non-converting in your starting days. You will not be getting any sales until you optimize your audience to the extent where "you reach the people who buy the same thing that you sell from your competitor." 

Examples and case studies go on and on. The crux of the matter is that most of your time and money investment will be wasted if you invest in quantity only.

One should always invest time and money in attracting people who have a history if interest in his/her niche.  

Ideally, a good digital strategy should result in high volume of quality traffic to a website, still we know in real life such a situation is far away from realistic. The trade-off between quantity and quality is a common issue that businesses have to face. What is volume, though, if only a tiny portion of it converts to sales or meets the comapny's business goals? A moderate volume of prospects with high potential for purchasing is always a better idea than a mass of one-time visitors. Therefore, a business should invest in bringing quality traffic and nourishing excellent relationships with visitors so as to achieve its goals best. In three words: "Quality over Quantity!"

It depends on the nature of business you are running. Some business needs traffic while other needs quality traffic. 

Quality traffic could be the potential buyers on your website. The ones interested in your services or products.

In eCommerce case you should invest your time and money to built quality traffic

This is a critical trade-off, multiple factors that have to do with what is the kind of business you are running are involved. A suitable answer optimizes both options properly. Moreover, in practice there are situations where you need to enhance amount of traffic over the quality or vice versa. I think it's risky to enhance one option and leave the other unchanged (Dynamic management for both options is required). 

I will invest time and money both in increasing the quality of traffic to my website. Because quality matter more than quantity. Less quantity with good quality of work is better than having a large quantity 

Time is a critical factor in the competetive world and therefore should be wisely invested.The answer to the question depends on the context and would change according to the industry and its requirement.If the objective is to achieve brand awareness then increasing the amount of traffic would have an immense contribution in achieving the goal. On the contrary of we are looking to boost sales for an ecommerce company the quality of traffic is pertinent.

Online lead generation techniques vary with the platform being used (SEM, SMM, SEO). The aim being to get the maximum quantity of targetted leads to the website / landing page which can then be converted to qualified leads depending on the quality of the content, design on the site. The leads targetting filters vary by the type of business but is generally by-region, by-keyword (for SEM, SEO) along with a few more filters like by-agegroup and other demographics (for SMM). 

Basically when the approach and strategy is adopted based only on increasing the traffic and gaining the top spot in SERP without concentrating on the quality will not help in the long run as there are chances where high quality content will replace less/no quality content in mean time as internet and its trends keeps evolving. So its best guideline to focus more on quality traffic which will help in conversion rather than just increasing the traffic for no/minimal reason.

Ofcourse invest time and money in to online marketing SEO or SEM. it is good return in business, without marketing there is no scope to grown up your online business now a days, and without traffic website and online store it selv's  no value.

Best option for generate real quality traffic is from "Google Adwords", "Facebook Marketing", "YouTube Video Marketing"
