What law firm SEO means when the answer is a paragraph
For twenty years legal SEO was a race for position. Ten blue links, and the firms above the fold got the calls. An assistant does not present ten options. It writes four sentences and names a short list of firms, and the person reading it almost never opens a results page afterwards.
That changes what the work is. You are no longer arguing that your page deserves position three. You are making sure a model can say, correctly and without qualification, that your firm handles custody matters in your county, that a consultation is free, and that clients say the process was explained to them.
Everything below is ordinary law firm SEO done for that purpose. None of it hurts your Google position. Most of it helps.
