If it is not something you can find or find yourself, or if it includes designated technologies directly on your site, you are able to ask questions and get answers. Deal with respect to others with whom you want to behave. This is the old gold rule, but applies to the SEO industry.
If you are irregular and inconsistent with your SEO companies, they will work with you on your own. Remember, if you knew everything about SEO you would be recruiting an SEO agency. Give your SEO company some rooms and allow them to hire a job that you’ve hired to do them.
