If you're an e-commerce site owner wishing to optimize the site for search engines for the best rank & most traffic, first & foremost make sure you've patience. Reason is, SEO was 'never an overnight process and will never be'.
It genuinely takes time in targeting some good search terms, on-page & off-page works, making the site socially active (social media activities) and outranking your competitors. Not all business owners are SEO experts, they need to consult or hire SEO firms. This creates a chance for the bad SEO organisations to falsely educate site owners about giving the quickest result, at cheapest price, with the most no. of links and traffic and so on. They apparently look like fakes, don't they?
Here're the points to help you recognize those
backlinks seo agencies and their badass commitments.
Links - their no. and quality
If you talk about SEO, link building strategy comes first. The nature of fake agencies is - either they don't disclose their strategy or make some super hi-fi sentences like building hundreds and thousands of links.
If this is the case, move straight away because most of those links will be low-quality and bear no worth.
Right to your contents & links
Bad companies take the money from you to build high-quality contents, links, blogposts and guestposts. As soon as your contract finishes they take down all the links and guestposts. That's why I call them badass.
