Hi,
Use of structured data :- You may have come across the Featured Snippet within the search results on a number of occasions. It's appearing more and more frequently for question-based keywords.
Link Reclamation :- this tactic is all about finding when someone has mentioned you, your business, your product/service or your content without actually linking to you. Once you find someone that's done this you can then get in touch with them and simply request that they add a link to your website.
Write Consistently :- Search engines love frequently updated sites. But more important than that, users do. A site that’s updated consistently tells users you’re serious about providing good content, which makes it worth it for them to invest their time into reading it.
Checking for Links :- There are ways to do a bulk search on a list of URLs to check if any of the pages contain a link to yours, but if you're checking this on a daily basis, it's probably just as fast to do a quick manual check.
Competitor Link Analysis :- There are a lot of resources out there surrounding competitive link analysis.
Play by the rules:- You won’t get ahead by trying to take shortcuts. Unfortunately, many SEOs try to use unethical practices, also know as black hat SEO, to try to trick search engines into giving them a higher ranking. Anything promising quick results will most likely result in penalty, or worse, your site will be removed from Google’s index altogether.
