The short answer: most small and mid-size law firms are quoted between $1,500 and $5,000 a month for SEO. A GoodFirms survey of more than 300 agencies found 48% of them charge in that band and another 43.3% charge less than $1,500. Large legal agencies that run big multi-office firms charge a lot more, often well into five figures.
That range is real, but it is not very useful on its own. Two quotes at $2,500 a month can buy completely different things. For an immigration firm the more useful question is what the money builds, because immigration has a few cost drivers that a personal injury or estate planning firm does not.
What actually drives the price for an immigration firm
How many case types you handle
Family-based immigration and business immigration are two different markets. A firm that only does marriage green cards and naturalization needs a handful of strong pages. A firm that also handles asylum, removal defense, H-1B, L-1, O-1 and PERM needs a real page for each, written for very different readers. More case types means more pages to write, keep current and link together, and that is where most of the work goes.
How many languages your clients search in
If a large share of your clients search in Spanish, Mandarin or Tagalog, the pages they need have to exist in that language, as real pages Google can index. That roughly doubles the content work for every language you add, and each translated page needs a bilingual reviewer before it goes live. I cover this in more detail in multilingual SEO for immigration law firms.
How crowded your city is
Ranking for immigration lawyer in Houston or Los Angeles takes more work than ranking in a mid-size city with three immigration firms. The work is the same kind, but there is more of it, and it takes longer before the map pack moves.
Where your site and profile are starting from
A firm with a clean site, a well-set-up Google Business Profile and a steady flow of reviews needs less foundation work in the first months. A firm with a slow site, the wrong primary category and three old addresses scattered across directories needs a heavier start before any of the ongoing work pays off.
What cheap immigration SEO usually is
At the low end, the pattern is predictable: blog posts bought in bulk from writers who do not know the difference between adjustment of status and consular processing, Spanish pages run through a translation tool and never read by a human, and links from sites no real person visits. It looks like activity in a monthly report. It rarely brings in a consultation.
In immigration the content problem is worse than in most practice areas, because the facts move. USCIS raised most filing fees on April 1, 2024: the I-130 went to $675 on paper and $625 online, and the N-400 to $760 on paper and $710 online. A page still quoting the old numbers tells a careful reader that nobody at the firm is watching the details. AI engines are built to avoid citing stale answers on fast-moving rules, so the same page also drops out of ChatGPT and Google's AI Overviews.

Google Ads is the obvious comparison. WordStream's 2026 benchmark puts the average cost per click for attorneys and legal services at $9.87, the highest of any industry it tracks, and the average cost per lead at $131.63. Immigration usually costs less per click than personal injury, with estimates running from about $5 to $20 depending on the city and the keyword. Those clicks stop the day the budget stops.
SEO costs the same each month whether a hundred people find you or a thousand, and the pages keep working after they are built. It is slower. Most firms need four to six months before the trend is clear. I wrote a fuller comparison in SEO vs Google Ads for immigration lawyers.
Questions that tell a fair quote from a cheap one
- Which pages will you build in the first three months, and for which case types?
- Which languages, and who reviews the translated pages before they publish?
- Who writes the content, and does an attorney at my firm approve it before it goes live?
- What do you do about Google Business Profile and reviews, not only the website?
- What does the monthly report count: calls and consultation requests, or only impressions and rankings?
- Do I own the site, the content and every account if I leave, and how long is the contract?
If the answers are vague, the work will be too. If a company will not tell you who actually does the work, that is usually because it is not the person you are talking to.
How I price it
I do not quote a number off a shelf. I run a free audit first, look at your site, your profile, your city and what ChatGPT and AI Overviews say about your firm today, and then quote against what your firm actually needs. There is no long contract, and everything I build lives in your accounts. If the audit shows your site is in good shape and the gap is somewhere else, I will tell you that too.
