How to Do Keyword Research for SEO Strategy?

Before commencing keyword research, find out the topics you wish to target. These topics can generally relate to your business in a close group or a broader sense. It is essential to consider buyers' cogitation and compile a list of issues that would allow your business to be discovered by the target audience.

Step 2: Shortlist Keywords and Phrases to Identify Sub-Topics.

The next step is finding keyword phrases to help you rank in SERPs. These are the exact keywords that the potential customers are searching for. Targeting these strings of keywords will return your web pages in search engines. Use various analytics tools such as Google Analytics to distinguish the keywords prospects use to discover your site.

Step 3: Focus on Related Search Terms.

While targeting keywords, you must thoroughly cover multiple keywords or strings to grab a spot on search result pages. You may manually discover different search terms by searching for a specific topic on and scrolling to the bottom of the results. You will find several other long-tail or short-tail search results related to the original keyword that you should consider.

Step 4: Analyze Your Competitors

Ranking on SERPs does not solely depend on your SEO campaigns. Instead, the SEO tactics applied by your competitor can affect your ranking. If your competitors have an active keyword strategy, your website will likely rank behind theirs. You can take the help of various SEO tools to analyze their site. You may focus on the keywords your competitors are ranking for and the keywords they have ignored since this may serve as an excellent opportunity for your website to create its market share on different terms.

Step 5: Trim down the Keyword List.

Keywords help the crawlers identify the topic you are offering. But it is vital to avoid keyword stuffing in the articles. Although Google has not specified the exact keyword density, SEO experts believe that the ideal percentage of general keywords is somewhere between 2% to 4%. If keywords are used excessively in an article or web page, the chances of Google penalizing the website are exceptionally high. The Google AdWords Keyword Planner is an efficient SEO tool showing the shortlisted keywords' volume and traffic approximations. This will help you eliminate low-volume keywords and narrow down your list.

How to Improve Your Local SEO Ranking?

For your business to capture the attention of nearby prospects, SEO specialists must enlist a robust local SEO strategy.

  • Single Domain: When a company targets multiple geographical areas, it may be tempted to design websites using separate domains for individual locations. However, this may harm your SEO marketing efforts since each domain's content, links, and keywords will clash with the attributes of the other. Using a subfolder within the primary site is advisable to manage and highlight the multiple locations where you offer services.

  • Location-Specific Content: To rank on local search engine pages, you must create content relevant to the focus area of your business. Optimize on-page elements for individual target regions. For instance, conceive page titles, H1, HTML tags, and the content and image in a manner that resonates with the local population. Businesses offering services in multiple regions must create a unique ‘Location’ landing page that branches out further to include separate location pages.

  • Claim Your Business Listings: To improve your standing in local search results, you must create and claim your business listing on 'Google My Business' and various online directories like Yelp, Bing, etc. You should also provide added information such as contact details, working hours, available services, etc. This will streamline your business's data and allow local prospects to discover your company effortlessly.

​​​​​What Is the Difference Between White Hat SEO V/S Black Hat SEO Techniques?
  • White Hat Technique: White hat SEO is an ethical and technical practice focusing solely on the requirements and interests of the audiences as opposed to the SERPs rankings. White hat SEO creates a steady, long-term layout to garner organic search traffic to the site. The SEO experts consider the guidelines established by the Search engines to warrant exceptional user experience. The primary white hat techniques incorporate generating quality inbound links, creating original, engaging, and informative content, using keywords, keyword analysis, keyword-rich meta tags, etc., to constantly improve the SEO ranking. 

  • Black Hat Technique: Black hat refers to SEO techniques and strategies where unlawful practices are implemented for higher search rankings. Black hat SEO is considered a 'quick-fix' to appeal to the bots in search instead of focusing on audiences. Although this SEO technique may offer a quick return on the site, it is a rather harmful practice in the long run. Google is known to ban websites from search engines or de-index as a penalty for malpractices. The most common black hat techniques include link farming, keyword stuffing, hidden texts and links, plagiarized content, misleading redirects, etc.

What Are The Most Common SEO Mistakes to Avoid?

Google's algorithm is ever-changing. Hence, SEO experts have to improve their tactics to get results constantly. However, there are particular mistakes that the algorithm despises. If these activities are enacted, the site can suffer significant damage. 

  • Intrusive Ads or Sneaky Redirects: A page filled with irrelevant and bothersome ads will fail to rank high on search results. At times, the ads and the page content are difficult to distinguish. This will compel Google to categorize the site under the "bad user experience" column. In addition, if there are unnatural links from the site, Google will detect them and implement a ban on the site.

  • Hidden Texts: Certain agencies hide main keywords using white text on a white background. They employ this tactic so only the bot can spot it while crawling the site. But this practice can get the site permanently banned from search result pages. 

  • Plagiarized Content: Search Engines hate duplicate content. SERPs display content that is original and unique on the top. Whereas websites posting copied content frequently will be penalized.

  • Avoiding Social Media Marketing: Social media marketing is considered to be one of the indirect ranking factors. The top social media marketing companies will help boost the reach of content. This, in turn, will increase the chances of gaining credible backlinks from reputed sites. In short, by avoiding social media marketing, brands can lose an enormous opportunity of boosting SEO rankings.

  • User-Generated Spam: Guest posting or user-generated content is a great way to post unique and engaging articles on the site. However, low-quality or gibberish content published without moderation will cause a decline in the ranking on SERPs.

​​​​​​Which are the Most Valuable SEO KPIs?

The responsibilities of the SEO experts do not end after the implementation of the SEO marketing strategy. They must keep a constant watch over their performance. Key performance indicators (KPIs) are measurable metrics that indicate the campaign's success.

The most vital SEO KPIs are as follows:

  • Organic Sessions: Organic sessions define the entire duration from the redirection of a visitor from the search engine to their exit from the site. The organic session also analyzes the activities of the user throughout the visit. An improvement in organic sessions indicates growth in organic traffic. Moreover, the increase in click-through rate aligns with getting more genuine clients, denoting a successful SEO marketing campaign.

  • Page Load Time: The loading time of a site can be a determining KPI. If a site takes a long time to load, the user is more prone to bounce back to the results page. This can also prevent the user from visiting in the future due to poor experiences. While redesigning the website, pay attention to improving the loading time by optimizing images and graphics of the site. 

  • Bounce Rate: The bounce rate determines the rate of sessions where the user does not perform any action and leaves immediately after the site loads. The bounce rate increases when the pages or content seems irrelevant to the visitors. Generally, it is considered excellent if the bounce rate is under 40. However, the ideal lowest bounce rate depends on the niche or industry.

  • Growth in Keyword Ranking: Monitor the website’s rankings for high-volume keywords. The site’s standing is excellent if the ranking is closer to number one. However, maintaining a close watch as an update in Google’s algorithm can create instability in the rankings. Focus on developing great content as well as link-building to boost ranking.

  • Conversions: An obvious SEO key performance indicator is the conversion ratio. If the site does not generate leads or convert inquiries to sales, the core business objective of expanding the customer base remains futile. Focus on Conversion Rate Optimization while ensuring exceptional user experience.

How to Recover From Google Penalty?

Before jumping into recovery, it is crucial to understand how to detect whether Google has penalized the site. The SEO specialists constantly run diagnostics on the website to look for any potential problem in the SEO strategy implemented.

  • Manual Penalties

    Resolution: First and foremost, ascertain the cause of the penalty, whether it is a link or thin content penalty. Next, put in efforts to rectify the predicament. Once convinced that the cause of retribution is remedied, submit a Reconsideration Request to Google appealing the withdrawal of the penalty.

  • Algorithmic Penalties
    With Google’s changing algorithms, it is likely that a specific activity is considered poor. This may result in a drastic decline in rankings and organic traffic. It may be challenging to identify the exact algorithm harming the website.
    Resolution: Take assistance from specialists with an extensive understanding of the algorithms to analyze the reason for the penalty. Eliminate link-related issues such as duplicate links, non-editorial links, paid links, etc. Also, focus on improving the quality of the content on web pages. Retaining a higher position on result pages may take time, but adopting SEO best practices will definitely pay off.
