Search Engine Optimization (SEO) is the process which increases a website’s rankings in search engine results and subsequently increases site traffic and revenue.
For example, a website that sells designer clothing would want to appear as the first search result whenever a potential customer searches for the phrase “buy designer clothes” in Google.
Ask past clients if they felt that this SEO provided useful service, was easy to work with, and produced positive results.
If you're thinking about hiring an SEO, the earlier the better. A great time to hire is when you're considering a site redesign, or planning to launch a new site. That way, you and your SEO can ensure that your site is designed to be search engine-friendly from the bottom up. However, a good SEO can also help improve an existing site.
Making the changes recommended by an SEO takes time and effort; if you aren't going to take the time to make these changes, it's not worthwhile hiring a professional.
Some useful questions to ask an SEO include:
I visited your website and noticed that you are not listed in most of the major search engines and directories..."
Reserve the same skepticism for unsolicited email about search engines as you do for "burn fat at night" diet pills or requests to help transfer funds from deposed dictators.
Beware of SEOs that claim to guarantee rankings, allege a "special relationship" with Google, or advertise a "priority submit" to Google. There is no priority submit for Google. In fact, the only way to submit a site to Google directly is through our Add URL page or by submitting a Sitemap and you can do this yourself at no cost whatsoever.
Ask for explanations if something is unclear. If an SEO creates deceptive or misleading content on your behalf, such as doorway pages or "throwaway" domains, your site could be removed entirely from Google's index. Ultimately, you are responsible for the actions of any companies you hire, so it's best to be sure you know exactly how they intend to "help" you. If an SEO has FTP access to your server, they should be willing to explain all the changes they are making to your site.
