Web Search Engine's Paid results timeline
Doing with PPC and target active keywords, you’ll see traffic increases almost immediately after you set your bid prices.
Web Search Engine's "natural", "organic (unpaid)", or "earned" results timeline
First month involves research and strategy into the client’s needs,
industry, competition, purpose, keywords, target audience, and not much implementation.
The second month implementation begins, but it takes time for search engines to recognize
the changes, so virtually nothing happens to results until the tail end of the second month.
When results start appearing in the third and fourth months, they’re going to be minimal.
By the sixth month things should be starting to move along nicely, but it will likely be closer
to 12 months before the real payoff starts. It’s in the second year that you will harvest
your investment.
