      PPC Review from Max Snitkovsky, MBA

      My experience with Klientboost was a complete dumpster fire, so I would highly recommend you AVOID this unethical company.I engaged with Klientboost with the goal of improving the performance of my ecommerce brand. Onboarding was OK, with Elisha and her team when they gather information about my business. For the first 2 weeks they developed a strategy that they presented to me, with the goal of improving my business. The next 2 weeks was spent executing that strategy before I realized I had wasted my time and money. Klientboost's strategy was a complete failure and all of my KPIs were worse off compared to before I engaged with Klientboost. That includes ROAS, # of Purchases, Conversion Rate, and Cost Per Acquisition. Before my business was consistent, and as soon as Klientboost took over, everything just plummeted. I paid an additional $1500 for "creatives". What I received back was a quote or short text, overlayed on my existing photos. There was no creativity whatsoever. This was a complete waste.Klientboost's big selling pitch is during the first 30 days they will make changes to improve your business performance, and those 30 days will be the benchmark for their next goal of increasing results by 20%. What actually happened is that they lowered my performance during the first 30 days, so that they could return to what I had before in the following days, so it is clear how they achieved their stated "20% growth goal". Very unethical.I highly recommend you avoid Klientboost!

      Digital Marketing Review from Sue MacGregor

      I hired KlientBoost early in 2024 to support our digital marketing efforts. As Head of Marketing, my main priority is to support our sales organization by feeding the pipeline and driving revenue for the company. KlientBoost came highly recommended because they produce results quickly. In the short time we have worked with KB, our digital marketing efforts have produced nearly $1M in pipeline. I can't wait to see what we do together in 2025.

      They delivery excellent results on the backs of hardworking vendors... which in turn, they do not pay. From a business ethics standpoint, it's worth looking into another agency who cares about their subs.

Frequently Asked Questions

What services do SEO agencies provide?

Top SEO companies provide services that improve your website’s visibility in search engines to increase traffic, leads, and revenue. Core services include: 

  • Keyword research: Identifying search terms your customers use so your pages target real demand. 
  • On-page SEO: Optimizing titles, meta descriptions, headings, internal links, and content to improve relevance and rankings. 
  • Technical SEO: Fixing site speed, mobile usability, crawl errors, and indexing issues so search engines can properly access and rank your site. 
  • Content creation: Producing optimized blog posts, landing pages, and other content that attracts and converts organic visitors. 
  • Off-page SEO: Acquiring backlinks, earning brand mentions, and managing citations to increase domain authority and ranking strength. 
  • Local SEO: Optimizing Google Business Profile and local listings to improve visibility in local search results. 
  • SEO audits and reporting: Analyzing performance, tracking rankings, traffic, and conversions, and refining strategy based on data. 

Can SEO companies guarantee a #1 ranking on Google?

No, a professional SEO agency cannot guarantee a #1 ranking on Google. Google’s algorithm is controlled by Google, not agencies, and rankings depend on competition, search intent, site authority, and ongoing algorithm updates. 

Search engine optimization companies can improve your chances of higher rankings by optimizing your site, creating quality content, and building authority. They cannot control final positions. 

Any agency that guarantees a #1 ranking is using a sales tactic or risky methods that can lead to penalties and traffic loss. Reliable SEO agencies focus on measurable growth such as increased organic traffic, more qualified leads, and higher conversions. 

How do SEO agencies measure success?

SEO agencies measure success using traffic, rankings, and conversions from organic search. The primary metrics include: 

  • Organic traffic: Number of visitors coming from search engines. This shows overall visibility growth. 
  • Keyword rankings: Position improvements for target keywords. Higher rankings increase traffic potential. 
  • Conversions: Leads, purchases, or sign-ups generated from organic traffic. This connects SEO to revenue. 
  • Click-through rate (CTR): Percentage of users who click your result. This reflects how effective your titles and descriptions are. 
  • Bounce rate and engagement: How users interact with your site. Strong engagement signals relevant traffic. 
  • Backlink profile growth: Number and quality of external websites linking to you. This reflects authority improvement. 
  • Return on investment (ROI): Revenue generated compared to SEO cost. This determines the business impact. 

How much do search engine optimization companies charge for their services?

SEO agencies typically charge between $500 and $7,500 per month, with most businesses paying $1,000 to $2,500 monthly. Pricing varies based on the agency, scope, and level of competition. 

Common pricing ranges include: 

  • Monthly retainers: $500 to $7,500 per month for ongoing SEO. Large or enterprise companies may pay $10,000 to $50,000+ per month. 
  • Project-based SEO: $1,000 to $30,000 per project for audits, site optimization, or migrations. 
  • Hourly consulting: $75 to $300, depending on expertise and provider. 
  • Performance-based SEO: Custom pricing tied to traffic growth, rankings, or revenue. 

Costs increase with competitive industries, larger websites, national or international targeting, and full-service campaigns that include technical SEO, content, and link building. 

How long does it take to see results?

SEO typically takes 4 to 6 months to start showing results, and 6 to 12 months to deliver significant traffic and revenue growth. The exact timeline depends on your website and competition. 

Typical SEO timeline: 

  • 1 to 3 months: Research, technical fixes, and content creation. Minimal traffic impact. Early ranking improvements may appear. 
  • 4 to 6 months: Noticeable ranking improvements, traffic growth, and initial leads or conversions. 
  • 6 to 12 months: Strong traffic increases, consistent rankings, and measurable business results. 
  • 12+ months: Maximum impact. SEO becomes a major and stable source of traffic and revenue. 

Factors that affect timing include website age, existing authority, competition level, content quality, and budget. New websites often need 6 to 12 months, while established websites may see improvements faster, sometimes within 1 to 3 months.
