A website may have 500 or 5000 visitors a month, and yet not get call or sales from a site, many clients don't understand this, and ask me what the problem is.
The problem can be various things, if a site has 5000 visitors and you are not getting any sales, often it's because people are not finding what they want on the site, they can't navigate the site, or they can't use the cart easily. Getting 5000 visitors a month, you should be getting some sales. The SEO or the way the site shows in search engines could be deceptive.
On most websites, about 60% - 70% of visitors bounce, which means they leave after only looking at one page. Of the visitors that go to a second page, about 25% leave the site on the second page.
Of the visitors still on your website, you will have some that are spam spiders looking for more email addresses. There is the visitors that are there to steal your images or words for their own websites or school study's, that's a large % of visitors to a website… a very large percentage.
Then you have visitors like me, that are only on the site for research, just to give you an idea, my internet history tells me I visit between 10 and 15 thousand webpages a month, over the paste year, and I buy perhaps 2 things online a year.
So that could be viewed as about 70,000 pages viewed per purchase, yet most of the time I would visit a maximum of 10 pages to buy a product, the other page views I make are researching for various SEO clients I have, or just out of interest.
I don't know anyone that visitors as many pages as I do, (people that visit as many sites as I don't generally have time to know other people that surf all day every day) but I'm sure that few of us visit your website a day.
So after all that, maybe .5 % are actually serious customers wanting to buy whatever you are offering. How many of them are actually at the "got the credit card ready" stage or are now just comparing prices or services.
You maybe thinking by now that websites are a waste of time, but with a good SEO … ok an excellent SEO like me, that works on getting quality, relevant clients to a website, that % of website visitors ready to spend money on your products or services can be increased drastically.
I have a dentist in Chula Vista, San Diego for example, that is getting between 4% and 5% of his visitors becoming patients, and we all know how much dentists charge for their services. This dentist had a website for 4 years, which generated not patients at all.
All of the chiropractor's websites I have worked my SEO wizardry on, have had a significant increase both to the amount of visitors to their website, and the % of those visitors becoming patients.
The ecommerce websites I have worked on, have most often gone from having few visitors, and no sales at all, to thousands of visitors, and thousands of dollars of sales.
