There are many factors to consider when determining how long it will take SEO results to be visible, including the age of a business's online presence, the quality of its content, and the competitiveness of its industry. New business may take up to six months to see the results from SEO efforts. For a business with an existing online presence, results from SEO can be seen almost immediately.
Some of these factors include:
-The keywords chosen.
-The relevance of your existing content for those keyword.
-The quality of your content vs competitors who are already ranking above your website.
-The age of your domain and your website.
-User metrics (e.g. how long a user stays on your website).
-The location of your business.
-The competitors you’re up against on Google and how established they are.
-How quickly changes are implemented from the start of a campaign.
