What is Website SEO?

SEO or search engine optimization is the improvement of technical characteristics and content of a website to meet the requirements of search engines and customer’s needs. During this process, specialists conduct an SEO website analysis to determine the areas for improvement. In addition, they analyze the position of a website among its direct Google Search competitors and build a strategy to improve its online ranking.

Generally, there are 3 main types of website SEO:

  • On-page SEO. This subtype of search engine optimization comprises keyword analysis, online content creation, and keyword optimization.
  • Technical SEO. This SEO type is about optimizing site speed, crawlability, website architecture, security, and responsiveness. In other words, SEO experts perform the technical website audit to find any technical bottlenecks that affect its SEO.
  • Off-site SEO. This SEO strategy is all about building backlinks and increasing the website’s authority for search engines.

To put it simply, search engine optimization is a sure way to improve a website’s ranking positions in SERP results. The better SEO a site has, the closer to the top it ranks.

Essential Role of SEO in 2020: Why Does Your Website Need an SEO Audit?

SEO is Google’s way to establish justice in Google Search. Without search engine optimization, it would be very easy to manipulate Google’s ranking positions. As a result, manipulators would be shown at the top of Google, whereas the websites with engaging and quality online content would rank lower.

Thus, although SEO requires additional effort from website owners, it introduces the order in Google Search. As a result, users receive more accurate and relevant online search rankings, whereas websites have clear directions on what they should improve to rank at the top. Even though Google doesn’t share all factors taken into account by its search ranking algorithms, there are many generally approved SEO techniques. These search engine optimization strategies have proven effective and can help your website outperform competitors in Google.

Try using Pingdom, PageSpeed Insights, WebPageTest, or any other alternative online checker. A one-second delay in page loading decreases the number of page views by 11%. That’s why software for online speed check is a must-use to keep your website afloat.
  • Rank tracking tools. Let’s say you have finished writing content according to all search engine optimization rules. What’s next? After the content is published, you need to make sure the articles and keywords properly rank on Google. To perform such analysis manually, you would need to type each keyword in Google to find your pages in SERPs. Don’t do that!
  • Keyword Research tools. No need to say that keyword research is the foundation of website search engine optimization. Advanced keyword analysis software significantly speeds up the discovery phase and brings numerous other SEO benefits. In particular, keyword analyzers can show the content gaps of your competitors.
  • SEO reporting tools. SEO reporting software is necessary for anyone who wants to rank in the top SERPs and stay there forever. The thing is that search engine optimization is a continuous process that requires monitoring and tuning-up. Such website checkers analyze website performance based on selected KPIs and regularly provide SEO reports.
  • CompetitTools. To launch a successful SEO strategy, treat competitors like your teachers, not like your enemies. Competitor websites have been in your industry for a while and introduced diverse SEO ranking techniques.
  • Local SEO tools. Although Google’s ranking is global, many buying decisions happen locally.

Such SEO optimization tools usually comprise an automated listings finder (to look for directory listing opportunities), automated update of all listings, review management features.
