How do I choose a good SEO agency and avoid the bad ones?

Choosing an SEO partner is critical – the right agency can boost your business, the wrong one can waste money (or worse, harm your site’s reputation with bad practices). Here are some tips:

• Ask about their SEO philosophy and practices: A trustworthy agency will focus on “white-hat” SEO – meaning strategies that follow search engine guidelines and build genuine value (quality content, earned links) . If an agency talks about secret tricks, or guarantees #1 rankings, be cautious. As one resource advised, any SEO agency that guarantees performance or promises thousands of backlinks overnight is not one worth trusting . Great SEO like SVZ provides is more science and effort than magic.
• Experience and Case Studies: Look at their track record. Can they share examples of other clients’ success (even if anonymized)? Do they have experience in your industry or a similar one? An agency should be able to point to specific metrics – e.g., “We helped X client grow organic traffic 200% in 12 months” – and ideally connect that to business results (like conversions).
• Questions to ask them: Inquire about how they do keyword research, how they earn backlinks, how they communicate progress. Good agencies will be transparent. For instance, you might ask “How do you approach link building?” and they should describe a thoughtful outreach or content-driven strategy, not something vague. Or “How will we know the campaign is working?” and they should mention regular reports with key metrics.
• Red flags: As mentioned, guaranteeing a specific ranking is a red flag – no one controls Google. Also, if they refuse to explain their methods (“proprietary process” with no detail), that’s concerning. If they mention tactics like mass directory submissions or buying links or using link schemes, steer clear – these black-hat methods can get your site penalized. Another red flag is poor communication: if they seem disorganized or avoid questions during the sales process, it won’t magically improve later.
• Communication and Fit: You want an agency that will treat you as a partner. That’s what we focus on here at SVZ. They should ask you a lot of questions too – about your goals, customers, past efforts – which shows they customize their approach. Chemistry matters; you might work with them for a year or more, so choose a team you feel comfortable with.
• Reviews and Reputation: Check their reviews on Clutch, Google, etc., and even ask for references. Other clients’ experiences can be telling. We have plenty of references and social proof at SVZ - maybe an overwhelming amount ;)

One handy tip from industry experts is to ask the agency to share some example questions they would ask you – good SEOs ask about your business model, unique value, customer demographics, etc., to craft a tailored strategy . If all their pitch is about “We will add meta tags and submit your site to 1000 directories,” that’s outdated and superficial - we at SVZ already include this by default within every site build.

Ultimately, a good SEO agency like is transparent, data-driven, and realistic, while a bad one is secretive, overly salesy with big promises, and uses one-size-fits-all tactics. SVZ, for example, often finds ourselves explaining to prospective clients why we won’t do certain things (like spammy link-building) and why a slower, steady approach is safer – this honesty sometimes surprises them if they’ve talked to more “black-box” vendors before. We also emphasize finding an agency that stays current; SEO evolves constantly, so you want folks who adapt and learn (through reputable SEO blogs, conferences, etc.).

As a quick recap, some questions you could ask to gauge an SEO agency include :

• “Do you focus on white-hat techniques? Can you give examples?”
• “What specific areas of SEO are your specialty – technical, content, link-building, local?”
• “Do you have experience in our industry or with sites of our size?”
• “How do you report progress and results? What metrics do you track?”
• Their answers will reveal if they’re the real deal.
