Frequently Asked Questions (FAQs)
Q1. How soon will SEO show results?
Usually 3 to 6 months. Traffic, rankings, and conversions grow gradually. Be cautious if an agency promises instant top results — that’s a red flag.
Q2. Can I switch agencies mid-project?
Yes — but it requires careful transition. Make sure you receive access to all assets (content, links, analytics) and ensure minimal loss of SEO momentum.
Q3. Does having an in-house SEO team mean I don’t need an agency?
Not always. Agencies bring tools, experience, and scale you may lack internally. Many businesses use a hybrid model.
Q4. How to estimate ROI for SEO?
Track organic traffic growth, leads, conversions, and sales over time. Compare the cost spent vs the revenue gained directly from SEO.
Q5. What’s local vs national SEO?
Local SEO focuses on your city or region (maps, local keywords). National SEO targets broader markets across states or countries.
Q6. Is it safe to hand over website access to an SEO agency?
Yes — when done with proper safeguards. Use roles, staging environments, backups, and access revocation post-contract.
Q7. Can an SEO agency guarantee #1 on Google?
No. No credible provider can guarantee that. Google’s algorithm, competition, and external factors make guarantees unrealistic.
