My business provides web hosting and website design for many companies. We normally do our own SEO work and get good success HOWEVER we have one client that cannot get back on page #1 of Google no matter what we try. We have changed search terms, we have added alt text to images, have had cache services like Cloudflare and plugins that speed up the website. We have checked toxic backlinks with SemRush and MOZ but not sure that is the issue. Our Domain credibility is low around 28/100 and not sure why.
You need to be the best in the industry for resolving issues that could be from speed and in-efficient script causing the first paint to be too slow or something like that. You need to be able to do fix these things yourself and not a team of people. I want one person, the person who is the expert to bid on this and work with me to resolve to the point of getting back on Page #1 in Google for our search words, mostly is just a 2 word phrase so you can focus on that without too many terms and phrases.
If this works out well, I will hire you for other projects.
