Luther Lindler Review from Google
2.0★
Luther Lindler's Review Sourced from Google
I give them 2 stars only because they did improve my Google search eaning with 6 key words. The cost? $3600 for 6 months- that's almost $1000 per key word. My main reason for dissatisfaction is they would promise things and not deliver. They also put work back on me, the customer, which they should have been able to do.First, they promised to place SEO rich text on my website. They wrote it and I edited it. Then they said they could not place it on my website diue to access. They asked me to have the CRM turn off two factor authentification because the way the work is not one single individual would need access. This was a no go. Finally after days of back and forth and me threatening them, they said they had access. However at this point I had given up and asked them to send me the text and I placed it on the website myself (even though I am paying them $60/hour to do this).Fast forward a couple months- again, they promise to fix an issue with website address duplication and to provide me other SEO rich text. 30 days later, this was still not done at our monthly telephone discussion. The website duplicaion was not fixed and they said the SEO text was a task for next month. This was when I caneled any further work which I had planned to do anyway since we had been at this for 6 months. They offered to put the website address fix money toward anoher tsk. However, when I asked them SPECIFICALLY what that task would be, I got NO ANSWER. This tells the story.Finally another major problem is there is NO consistancy in who you talk with. One month it is person A, next month person B, next month person C, next month person B again. I find their practices un-professional and they do not instill confidence in the customer. If I had it to do over again, I thnk I owuld look elsewhere knowing what I know now.

You can tell he’s in it for the long haul, and that mix of expertise and heart is rare—exactly why I trust his insight every time.

I have been working with Boostability for a little over 3 months now and my traffic went from around 300 to 2400! My organic keywords have also increased significantly. They give you a dashboard where you can go and check these numbers, but I do my own research with Google Analytics and SEMrush. I am very happy with the results!

Digital Silk was an exceptional partner in the design and development of NeuroAnimation's new website. Their team was very responsive and worked hard to accelerate the project to fit within a tight timeline. One thing that stood out while working with Digital Silk was the effort they invested in understanding our very unique business. They approached the project as though they were part of our own team, taking care to learn important details about our work, and that dedication was reflected in the quality and content of our new website. We are looking forward to continue our relationship with Digital Silk and would highly recommend them.

What services do conversion optimization agencies in the US provide?
They focus on improving how effectively a website turns visitors into customers. Core services include:
Comprehensive website and funnel audits: Identify friction, drop-offs, and performance issues. Faster pages convert better, and one-second loads can produce up to three times more conversions than slower pages.
Qualitative and quantitative research: Combine analytics and user feedback to understand intent, barriers, and pain points.
User behavior analysis: Use heatmaps, click paths, and session recordings to uncover confusion or hesitation.
Customer journey mapping: Redesign key steps to reduce friction and improve flow through the funnel.
Hypothesis development: Create evidence-based test ideas grounded in research and auditing findings.
A/B and multivariate testing: Run experiments to validate high-performing variations. Strong A/B tests can lift landing page conversions by roughly 30%.
Landing page and checkout optimization: Streamline product pages, forms, and checkout steps. Roughly 22% of shoppers abandon carts when the process is too long or complicated.
Content and design optimization: Improve messaging, layout, and UX to guide users smoothly. A seamless experience can increase conversions by up to 200%.
How much does conversion optimization cost in the US?
Hourly rates for conversion optimization in the US start from $55 and can reach up to $300. For per-project fees, the rates go from $5,000 to $100,000+, depending on scope, channel complexity, and program length.
Most US-based conversion optimization companies fall into three clear cost tiers:
Hourly Rates
$55/hr for smaller Shopify or WordPress optimization tasks
$100-$135/hr for standard CRO, UX optimization, and Shopify Plus work
$300/hr for enterprise PPC or multi-channel conversion programs
Project-Based Pricing
Under $5,000 for small, targeted CRO updates such as landing page fixes, SEO-driven conversion improvements, or short PPC experiments
$5,000-$20,000 for 2-3 month optimization cycles covering audits, UX updates, and basic testing
$20,000-$100,000 for full CRO programs for 3-6 months including research, journey mapping, A/B testing, and funnel optimization
$250,000-$1 million for enterprise, multi-channel CRO engagements spanning PPC, DTC, or large-scale eCommerce platforms over 12-36 months
When can clients expect ROI from a conversion optimization project?
The return on investment (ROI) typically follows a predictable timeline:
4-6 weeks: Early gains from fixing clear usability or funnel issues
3-6 months: Most clients see the strongest, measurable ROI within this window
Ongoing: Incremental improvements as validated tests replace assumptions
What is the typical timeline for a full optimization cycle, from initial audit to testing and rollout?
A full conversion optimization cycle typically runs 8 to 12 weeks and follows a structured sequence:
1-2 weeks of research and auditing
Hypothesis development and test design
A/B testing over several weeks to gather statistically reliable data
Implementation of winning variations across the site
Early improvements may appear within 30 to 45 days, but 2 to 3 months is the usual timeline to move from audit findings to fully implemented, data-backed changes.
How often do they review performance data and adjust during an active campaign?
CRO teams follow a set review cadence during active campaigns:
Weekly metric checks to identify early trends or issues
Monthlydeep reviews to adjust strategy
Post-test analysis immediately after each A/B test concludes
Mid-test changes only when a clear issue is detected
Quarterly audits to refine the roadmap and introduce new test ideas
Which business types do conversion optimization companies most often support?
These types of agencies work with companies of all sizes. DesignRush data shows:
~50% of clients are small businesses (<50 employees)
~20-30% are mid-market (50–249 employees)
~10% are large enterprises
