I am doing search engine optimization for a website which sells septic tanks. It is based in Ireland. Recently the website owner has uploaded some PDF files. The PDF files contains company brochures, installation drawings and some information about the products. All these PDF files have already been indexed in Google. My question is will Google drop my SERP ranks? Should i have to worry about Google indexing these PDF files?
Why do you think the PDF's would have a negative impact on the site's rank? If anything it's just more unique content that's available in a different format diversifying the site.
I don't think so, if you are providing good information about your product through PDF file then it can be good for your website in SERPs
It depends on the answers to the following: 1. Where did he upload these PDF files? 2. Do these files contain valuable and high quality information? 3. Are they well-written? 4. Do they contain an ample amount and legit backlinks? If your answers to numbers 2, 3, 4 are yes, then no, your rankings won't drop - in fact, they may positively influence your client's rankings.
