We are extremely proud of our success stories. Here are some case studies from clients for whom we have done a site quality review, as well as testimonials from other happy clients:

After our website suffered a steady decline in rankings for several months, I suspected that some black hat SEO link building that we’ve done in the past may have been the cause for this. So I started researching online on how to do a backlink audit. During my research I came across one of Marie’s articles which was very enlightening. I was then also referred to her by a leading SEO expert who said she was the best when it comes to site quality & backlink audits, so I reached out to her right away.

Marie’s team was very responsive and professional. I purchased their link audit and just got their extensive report back. It took them a couple of weeks, and I am highly impressed by the detail and thoroughness of the report. I will be implementing their recommendations ASAP and will be back for a site quality audit in the near future.

Thank you very much!

— Omer Reiner – FL Cash Home Buyers, LLC

First of all – this report was so detailed and informative. It was laid out clearly and contains enough information that even my team members who aren’t familiar with SEO should be able to understand it. That is SO helpful. Thank you!

— The Healthy Place,

Anthony here, owner of Pure CBD Vapors, an online CBD store in the U.S. My website traffic has dropped due to a Google core Update in 2019. It was really painful for me. Once I listened to Marie Haynes’ podcast on Google algorithm updates and then I have learned more about her expertise. I decided to hire her for our site review. They audited our website and provided us more than 200 pages of the report. Marie Haynes and her team did great efforts and provide genuine reasons. I and my team can see that in the report. They showed many issues and recommendation us many things to improve the website like EAT authority content, website speed, etc. Currently, we are working on Marie Haynes’ recommendations. I hope we will improve our website traffic and sale soon. The MHC team was professional, thorough, and responsive. I would recommend them for anyone dealing with website traffic dropped.


The work of Marie Haynes Consulting has been key for us to thrive in a post Medic update Google world. There are no shortcuts, but there is a way. MHC’s whitepaper on scientific consensus shows you exactly how.

She has helped us grow our website over the past few years and we are so thankful to have worked with her. Do the right thing and read her newsletter.

— Chad Kremp,

Marie is an exceptional SEO professional. She has offered us guidance and strategic insight into our organic traffic and rankings that have allowed us to take significant action. She is courteous, highly responsive, and is significantly knowledgeable in her area of expertise. We strongly recommend Marie to anyone looking for help with SEO.

— Shear Comfort,

Choosing Marie Haynes Consulting Inc was the best business decision I have ever made in my (most recent) business life.

Marie gave me insights on how to make dozens and dozens of adjustments and fixes to implement on my site and exactly how to carry them out. She also sent me follow-up emails on the fixes that I was confused about.

I also had the amazing experience to talk to her personally for her 1 hour live consultation after my assessment! (it felt like 5 minutes). It was amazing. She addressed every single one of my issues and sent me more emails with instructions.

She could have charged me 3X the amount that I paid her and I would not have blinked an eye. And I truly mean that.

— Charles Daidone, Owner,

Everything we knew about content creation and “link attraction” multiplied exponentially after receiving the first link audit report by the Marie Haynes team. The knowledge they shared with us has helped us develop healthily ever since, because we now feel able to assess the links we receive very confidently. We are grateful too for the tremendous boost that we just got in our rankings after the latest core algorithm change and this is partly due to the disavow that Andrew helped us put together. Simultaneously, we had spent nearly two years improving our content, usability and relevance following the guidance of MHC’s E-A-T insights, which elicited the very best in us. The positive results are a great motivator to keep being truthful and relevant, creating valuable content for the audience we are here to serve. Thank you so much for being our gurus in this journey!

Again, thank YOU and thanks to the whole team – keep being the best, please!

— Daniel, Co-founder of For the Ageless

Marie is a rarity in the world of SEO – she actually delivers what she says she is going to deliver! She is extremely knowledgeable, straightforward to deal with, great at communicating and thorough. As a UK ecommerce company, we were looking for the best in the business – and we found her. As a director of a UK ecommerce company, I can recommend her and her team without hesitation – I would recommend her services to anyone in the same situation as us – there is light at the end of the tunnel!

— Manual Penalty Removal Client

Marie is professional, very knowledgeable and prompt in responses. My site was in a “Pure Spam Penalty”. She did take a look at it, found the issues and prescribed the right solution. The process was very fast and the delays mostly were because of me being busy …. My request was approved by Google and few days later, the rankings are improving and have already few keywords showing back up on page 1 again. I am very thankful to have found Marie and asked for her help. I highly recommend her service….

— Pure Spam Penalty Removal

Marie and the team at MHC are outstanding and have been through the years. When first hired, Marie was able to have our penalty removed on her first attempt – something two large SEO companies were not able to do. We are thrilled to hear that Marie has hired a talented staff that she is training, and we are looking forward to some amazing SEO rankings moving forward.

— Eric M. Scop, V.P. Sales & Digital Marketing,

Given my prior experience with SEO companies, I was half expecting some boilerplate recommendations and a heavy dosage of copying and pasting. This was clearly NOT the case! I can tell you put some serious heart, time, and effort into this thing. All the recommendations were unique and personalized. To put it simply, I can tell you gave a f*ck, and it shows in everything you did/wrote.

— Site Improvement & Competitor Research Report for a large eCommerce site

I want to say a huge THANK YOU to Marie for her help at a B2B SaaS company where I was the Search Director. I had done years of off and on site improvements to get out of some kind of manual Google suppression my site was under. We were having trouble ranking for even our branded terms and were about 2 months from killing the domain completely and starting over with a new site. With Marie’s help, we were able to regain almost all of our rankings and organic site traffic went from 300 sessions/day to over 2,300 sessions/day. I can’t say enough about how helpful she has been and very well might have saved our business.

I recently paid 8K for a premium domain, but didn’t do enough research on it beforehand. After I had started publishing content I realized that the site had been very active about 15 years ago and had a massive amount of spammy widget and directory links pointing to it, many with exact match anchor text. It is literally the worst link profile I have ever seen.

Because of this, I decided to hire Marie Haynes and her team to do a full link audit of my site. They were able to find hundreds of domains with tens of thousands of seriously bad links pointing to the site. I have now uploaded the disavow file and I am hoping for the best.

The MHC team was professional, thorough and responsive. I would recommend them for anyone dealing with a bad link problem.

— Kris Gunnars,

Marie was the answer to our Google penalty issue.

She’s everything you look for in a contractor: she knows what needs to be done, is goal and milestone oriented, sends regular status updates and works methodically until the job is done.

We put our business in Marie’s hand and she delivered. She’s earned our trust and our respect. Hire her immediately.

— Manual Penalty Removal Client – Large Brand

Just wanted to thank you for the work you did on [site name removed for privacy]. According to Google Analytics the traffic between Oct 23 2014 – Dec 23, 2014 was 108,000 sessions. Compared to the same period last year there were 68,000 sessions. Your work nearly doubled my traffic!!!

— Google Panda Recovery Client
We are ranking on all of our brand name keywords now and all of our local office pages are starting to rank again, we noticed our office page is #1 for keyword “[keyword – city]” and for “[keyword – state]”, we are on page 1 already…Thanks Marie for making this happen. You are a true professional and made this entire process of link removal and documentation smooth.
— Manual Penalty Removal Client

When I first launched my website, (removed for privacy reasons) I had no knowledge of SEO so thought the best option was to employ somebody to do onsite and offsite SEO in order to help me rank well in the highly competitive field of wedding photography. My marketing budget wasn’t large but I found a low cost company who seemed to tick the boxes, gains were made and I landed on page 1.

As it turns out the gains were made due to low quality backlinks, directories and article posts. Sure enough google updated penguin and I dropped like a stone to page three. I put my trust in a company but due to their shortcuts I paid the price, losing business in the process.

After a lot of research I discovered Marie Haynes. I knew I had to get the problem solved and I wanted it done properly this time with no messing about or BS. Marie quickly did a site and backlink audit and also gave additional advise on areas to improve my website in the eyes of panda and penguin. Fortunately we had this done just in time for a penguin refresh and my site is currently sitting at number 1 – 3 for several my main search terms. Basically thanks to Marie’s expertise and knowledge my site is clean and back where it deserves to be. The advise was accurate and honest. Marie wasn’t just telling me what I wanted to hear. Without a doubt the best money I have spent on my online marketing.
