If you are planning to hire an seo agency or seo consultant then you need to ask few important questions which will help you understand whether your marketing firm has all the expertise required to handle your project or not.
×NOTE: THINK ABOUT WHAT WOULD HAPPEN IF THE SEO CONSULTANT OR MARKETING AGENCY THAT IS DOING THE WORK OF WEB POSITIONING SUDDENLY CUT COMMUNICATION (YES, IT HAPPENS MORE THAN IT SHOULD) AND LEAVE YOU WITH A POORLY OPTIMIZED WEBSITE OR EVEN MAJOR FLAWS. YOU SHOULD HIRE A SEO COMPANY TO SOLVE THE PROBLEM, AND NEED TO KNOW WHAT CAUSED IT.
×NOTE: THIS QUESTION DOES NOT USUALLY HELP TO KNOW IF THE SEO YOU HAVE IS FRONT RIGHT OR WRONG, BUT YOUR ANSWER WILL HELP YOU KNOW WHAT TO EXPECT FROM SEO COMPANY YOU HIRE (HAVE CLEAR EXPECTATIONS FROM THE BEGINNING MINIMIZE POTENTIAL FRUSTRATIONS OF BOTH PARTIES IN THE FUTURE).
×NOTE: SEE THE SUCCESS OF YOUR FUTURE SEO WEB PAGES TAKING THE ABYSS AND HOW YOU WILL AVOID SUCH SANCTIONS AFFECT YOUR SITE IN THE FUTURE.
×NOTE: YOU DO NOT NEED TO KNOW THE EXACT DATE OF THE UPDATE, BUT IT IS KEY THAT says SOMETHING LIKE: "THERE WAS A PANDA UPDATE IN JULY AND AN UPDATE XYZ a FEW MONTHS BEFORE."
It requires a lot of knowledge (also has to be continuous) and knows thoroughly to Google (in case you did not know, Google makes updates their algorithms every month). Do not believe who promise you the moon and the stars for $100 a month, because it is not possible. While the market analyzes and chosen based on the work performed, their knowledge, their brand and opinions from other customers.
Hiring an experienced SEO services Company is not cheap!
