The short answer is "it depends, but more than likely yes." Investing in a managed an scalable SEO strategy can be the kind of marketing effort that pays dividends slowly (but surely) over time. If the validity and value of the organic traffic you are generating is high, and these customers are qualified buyers ready to make a purchase, then focus on growing the denominator (i.e. the pool of traffic from this source) is exactly what you should be doing right now. Generally speaking, as you increase in size the overall ratio of value to traffic size will diminish, but again you make up for that in the aggregate of a larger pool from which to drive purchases.

It's not so much a function of should you or shouldnt you, it is really more a function of to what extent you should be. I would say that (generally) investing in your SEO growth is a plan that will more likely generate medium-term results; if you need an immediate boost in driving sales then I would consider other campaigns such as looks-alikes on FB (if you have a good following there) or perhaps re-targeting for abandoned site visitors.

Are you utilizing and growing an email list from the people who visit your site? you might want to consider ways to monetize more of the numerator as well - in that if you can get email addresses with something like a lightbox roadblock pop-up form or something when visitors first hit the site you can set them up on a drip and drive re-capture opportunities back to your site.

happy to hop on a call and discuss further if you want to get into more details/ideas.

First things first, it's pretty easy to take a look into your analytics and identify the source of this traffic, try looking just by acquisition channel or source/medium in GA.

Secondly you need to ascertain the total organic potential and competition, based on the total volume available and competition you may have already hit a point close to saturation. Conversely there may be a huge opportunity that you haven't yet tapped into, making it very affordable.

The third thing is about risk mitigation, I'm always a big proponent on diversifying marketing and traffic sources as there will always be fluctuation, similar to diversifying your risk in stock portfolios, it's worthwhile looking into this as well.

Happy to discuss further on a call if you'd like advice on this from someone's who handled this on small up to multinational sites.

Cheers,

I'd recommend focusing on both your SEO and paid advertising, as they serve different purposes and can both be extremely valuable. SEO is inherently a long-term strategy - it takes time to build up authority, get backlinks, and rank for various keywords - but it also has huge payoffs that accumulate over time.

Paid advertising is a very immediate solution that allows you to generate awareness, traffic, and leads quickly. With a sizable enough budget, you can collect data in a short timeframe and use that insight to scale your efforts and increase ROI from your campaigns.

Your keyword strategy should take both organic and paid into consideration, and should also play an important role in optimization of your website and landing pages, to which all of this traffic will be directed.

Hope this helps - let me know if you'd like to discuss further!

If you want to continue to grow inorganically then yes. Consider leveraging your new customers and use social strategies to attract their friends and family. Growing organically is much more profitable in the long run.

Thanks.
