Another tip you can use is just reach out to the prior agency and say something like the following: “We realise you were using link networks for our website which has resulted in a Google penalty and loss in business. Can you please remove my website from any link network you have built?”. If the prior agency is decent, they will remove the links from the network.
Organic search engine optimization (organic SEO) refers to the methods used to obtain a high placement (or ranking) on a search engine results page in unpaid, algorithm-driven results on a given search engine. Methods such as boosting keywords, backlinking and writing high-quality content can all improve a site’s page rank. Black hat SEO methods, such as the use of keyword stuffing and link farming, can also boost organic SEO.
Remember when you used to rely solely on search engines for traffic? Remember when you worked on SEO and lived and died by your placement in Google? Were you #1? Assured success. Well, okay, maybe not assured. Success only came if the keywords were relevant to your site users, but it was the only real roadmap to generating site traffic and revenue.
