Im looking for an expert seo advice

Hello. So im looking to see if someobe can give me some advice or maybe know the right person for this. I own a service company and we provide services like garage repair, locksmith,carpet and more. There is a big company in the same city but they work all over usa.
The way tgey work is that they have a different webside for every city they work at in usa and almost all of the sites are on the first page on google.
I checked and it seems that the almost dont have any backlinks or article submissions.
My question is how do they do that and if i can find someone that can help me do that. Thanks.

If you want to do what you read in the articles, feel free to PM me.

Do they have different sites or just different pages of the same site? ( which is more likely)
They could be using PBN's and blocking the links (Likely)

i think they must have hired someone to do this for them. And as above post PBNs might be woking for them.

if you did on page SEO, perfectly there is possible- your website will be in first page of google

copy them

Good question. Ranking for keywords
Such as ( service + cities ) is pretty simple ( if you do SEO for a living. If you PM me I can send you current websites I ranked.

I do not suggest doing SEO yourself. ... Doing SEO & website design yourself would be the equivalent to hiring Kim Kardashian saying she wants to fix her own plumbing instead of hiring a professional.

So.. some basic questions ...

1. Do you have a verified google business page?
2. Do you have a website? ( I still need to analyze content )
3. Have you had your website for at least a year?
4. Do you have content on your website?

---> if you don't have any content, start putting some together and then seek a professional. Unique content is very important and only you as the service provider can create that.

As for your competition...if you want you can PM me website and keywords and I can tell you how they do it and how you can gain a competitive edge.

Also let me know the following:

--what keywords / cities you want to target.

after analyzing that information I can give you an estimated level of effort and tell you how much it would cost to do and you can decide from there..
