So, you have downloaded your links profiles on a CSV and you now have an extensive list of all your linked domains. If you have been doing SEO for 8+ years like me you can probably just know from analysis which links are bad from a TLD and URL point of view. If you do not know too much you can use tools such as Link Detox: to complete analysis of your link profile. I would always consult the advice of an expert SEO in this instance because it is easy for these tools to mistake good and bad links.
Now in your reconsideration request make sure you are honest and tell Google everything that the prior agency was up too. Be sure to include all Excel information of removed links and say you are going to make an ongoing effort to remove everything negative. It is common knowledge that Google may not accept your first reconsideration request, so it may take a few times.
The last thing you need to do is evaluate the results and simply do it all over again. You will need to be constantly reassessing your organic marketing plan. The situation, audience, and goals will be constantly changing. Your marketing plan will need to change to adapt to this flux. You should reevaluate your organic marketing strategy at least every quarter.

Another way search engine marketing is managed is by contextual advertising. Here marketers place ads on other sites or portals that carry information relevant to their products so that the ads jump into the circle of vision of browsers who are seeking information from those sites. A successful SEM plan is the approach to capture the relationships amongst information searchers, businesses, and search engines. Search engines were not important to some industries in the past, but over the past years the use of search engines for accessing information has become vital to increase business opportunities.[31] The use of SEM strategic tools for businesses such as tourism can attract potential consumers to view their products, but it could also pose various challenges.[32] These challenges could be the competition that companies face amongst their industry and other sources of information that could draw the attention of online consumers.[31] To assist the combat of challenges, the main objective for businesses applying SEM is to improve and maintain their ranking as high as possible on SERPs so that they can gain visibility. Therefore, search engines are adjusting and developing algorithms and the shifting criteria by which web pages are ranked sequentially to combat against search engine misuse and spamming, and to supply the most relevant information to searchers.[31] This could enhance the relationship amongst information searchers, businesses, and search engines by understanding the strategies of marketing to attract business.
If you check out some of the suggestions below this though, you're likely to find some opportunities. You can also plug in a few variations of the question to find some search volume; for example, I could search for "cup of java" instead of "what is the meaning of a cup of java" and I'll get a number of keyword opportunities that I can align to the question.
Black hat SEO refers to the practice of trying to trick the search engines into giving you higher rankings by using unethical tactics, such as buying links. The risk is just too great. Even if you enjoy a temporary boost in rankings due to black hat tactics, it’s likely to be short lived. Google is getting better and better at spotting dirty tricks and sooner or later the progress you made will be wiped out by an algorithm update, or worse, your site will get removed from the index altogether.
Organic is different. Matching keywords to user intent means you may be present in many searches. The user may find you consistently, and once they get to your site, they are more likely to stay. Organic users are still your best long-term customers. In my experience, they have lower bounce rates and more pages visited, and they are more likely to return.
