I am a digital marketing & SEO consultant with over 12 years of experience in many sectors, including B2B services, ecommerce, local SEO, and more.
I agree with Jeff here. If your ROI really is trackable and if it converts as well as you say, then I'd try to get some excellent testimonials ASAP.
If results are that good, getting some excellent testimonials will help your customers do the selling for you.
Try offering a trial to a few key players - folks who have influence over others in your audience.
Also, look for other partners - Anyone who has influence over your target market because, once you have a few amazing testimonials (and I don't mean lots of superlatives in the headlines here... I mean like:
"How [Big brand name] saw 'x00%' ROI in 'y' Days..."
Then I'd go for some partners and offer them an affiliate/referral deal to get your next few sales.
If Ecom is your target market too, how about running platform-specific offers or deals? E.g. Woocommerce users (ads to them), Shopify users (ads to them)... And/or partner with Woocommerce designers, Shopify designers etc... folks who influence the people you're targeting and are already trusted by them.
Win over 1 or 2 Shopify / Woo designers by showing them great results and offering them a % of sale... you stand a chance to grow faster as they'll likely have the ear of ecom site owners, and be trusted by them.
Sorry if this is a bit of a convoluted suggestion... I have man flu today so am not thinking as clear as normal!
- Crawl the existing site - save to Excel
- Run a search in Google for:
Then export the list (use Chrome SEO quake extension) and add to Excel
Put both lists into 1 Excel file & de-duplicate.
Next, get the sitemap of your new site, so you have all the URLs.
Then map every old page from the site crawl and Google site: command search export to a NEW URL on your new site structure. Try to match to relevant pages.
This way you can build '301 redirects' from the old URLs to the new ones, to help avoid too much loss of link equity (and avoid too many 404 error page views by visitors!).
If there's a lot of pages, prioritise older (old structure) pages that have:
1) Most number of backlinks
2) Most amount of traffic (if you have Google Analytics access).
Lastly, if you can access server log files, you can parse this info from these and look for other pages to redirect... though this is quite a lot more advanced.
Oh, and yes - Google Search Console (WMT) - you can check for 404 error pages there to redirect to (ideally relevant!) pages on the new URL structure.
Hope this helps!
