FAQs

Q.1 Why is SEO so expensive for law firms?

Ans. Legal keywords (e.g., “car accident lawyer”) are among the most expensive in the world, often costing $100-$500 per click in PPC. Best law firm seo agencies charge premiums because the work required to rank organically for these high-value terms involves creating expert-level content and securing high-authority backlinks.

Q.2 What are Local Service Ads (LSAs)?

Ans. LSAs are the “Google Screened” ads that appear at the very top of search results. They are critical for law firms because you pay per lead, not per click. Agencies manage the verification process and dispute invalid leads to maximize ROI.

Q.3  Can agencies guarantee #1 rankings?

Ans. No agency can ethically guarantee a #1 ranking due to Google’s ever-changing algorithm. However, best law firm seo agencies will guarantee a strategy and workflow transparency that historically leads to top placements.

Q.4  How do I measure the success of my law firm SEO?

Ans. Success should be measured by “Qualified Leads” and “Signed Cases,” not just traffic. Top agencies integrate with your CRM (like Clio or Filevine) to track exactly which keywords generated the cases that turned into revenue.

Q.5 Is content marketing important for lawyers?

Ans. Yes. Google’s E-E-A-T guidelines require legal content to be authoritative. Agencies employ writers with legal backgrounds (J.D.s) to write accurate guides that build trust with potential clients and search engines.

Q.6 How long does it take to see results?

Ans. In competitive practice areas like Personal Injury, it can take 6-12 months to see significant organic movement. However, best law firm seo agencies often use a hybrid approach with PPC to generate leads while the organic strategy builds momentum.
