WEB SPAM: Re:  Error In Your Website…?

Hello,

My name is Jeff  and I am a Digital Marketing Specialists for a Creative Agency.

I was doing some industry benchmarking for a client of mine when I came across your website.

I noticed a few technical errors which correspond with a drop of website traffic over the last 2-3 months which I thought I would bring to your attention.

After closer inspection, it appears your site is lacking in 4 key criteria.

1- Website Speed
2- Link Diversity
3- Domain Authority
4- Competition Comparison

I would love the chance to send you all the errors that at least give you a gauge on the quality of what I do.  

If you are interested then please share your Phone number and requirements.

Our prices are less than half of what other companies charge.

Thanks
Jeff Carner
