Google Search Engine Ranking Factors
The difficulty of attracting customers is 
known to every entrepreneur, especially today with various adverts 
annoying us at every step. Marketing experts have come up with hundreds 
of tricks that are working in the media, on the radio or TV. Traditional
 advertisement can be used on the Internet too, albeit, less 
effectively. People tend to visit websites that somehow relate to their 
interests.  Therefore number of ad banners is not as important as 
website’s positions in search results.   
As proved by Alexa statistics and other 
reliable sources, Google.com has been considered the most popular search
 engine for many years, taking first place in the popular search engine 
rating for August with its 1,100,000,000 unique monthly visitors. Bing 
and its 350,000,000 visitors/month take the second place and Yahoo, used
 by average number of 300,000,000 persons per month takes the third 
place. The leadership is indisputable, because the rating took both 
global traffic and U.S. traffic into account.  
Top positions in Google are the main goal 
of every webmaster. And there has been no better website promotion 
method invented than SEO. Relatively cheap, this method proved to be lot
 more effective than advertisement. The concept of Search Engine 
Optimization is too wide to be narrowed down to a simple rules list. 
Moreover, Google is constantly perfecting the website ranking 
algorithms, prompting SEO experts to work on new methods. Nevertheless 
it is possible to single out basic SEO success factors that are still 
relevant in 2015.
On-Page SEO factors
1. Domain-level. 
Search engines are negative about large 
subdomain number. With correct optimization a website on one basic 
domain has more chances to take leading positions in Google SERP. Also 
it’s easier to build up weight and improve off-page factors on the basic
 domain. Experienced SEOs will help create correct subdomain and 
SEO-URLs structure that will include optimum keywords.  
2. Meta tags.
Meta tags are the search engine’s guiding 
lines that allow Google to obtain the main info on the website. During 
internal optimization SEO-expert makes relevant tags for the website:
- Title. You can see Title text when moving cursor to the tag of the website opened in the browser. The title must reflect the web-page’s content, feature keywords and have no commas. Maximum Title length for is 54 symbols without spaces (65 symbols with spaces).
 - Description. It’s a description of the page that the user sees in Google search results. Maximum symbols — 250. Description must contain keywords. If the Description is absent, the search engines generate it automatically using the text on the website.
 - Keywords. Meta tag, that provide the system with information about website’s content. SEOs use special tools to select keywords and base their selection on the Google data.
 
3. Sitemap.
Sitemap helps Google search bots to index the website. Only SEO experts can make a correct Sitemap.xml file.
4. Robots.txt.
 Robots.txt contains rules for the search 
engines. It can block separate pages, archive folders and folders with 
user data from the indexing. One extra symbol may prevent the entire 
website from getting indexed, so only experts should work with 
Robots.txt. Incorrectly written Robots.txt file has frequently impeded 
position growth.
5. Duplicated pages. 
The presence of duplicated pages can 
render all website optimization works null. Google is very critical 
about this aspect, so the experts check the exclusivity of web-pages in 
the beginning of the SEO-campaign.
6. SSL certificates.
First of all, SSL certificates are 
obligatory for e-commerce websites. SSL certificate doesn’t affect the 
search engine ranking itself, but it increases trust. As a rule, Google 
ranks safe websites higher.  
7. Content.
 Google content requirements get stricter 
with each year.  It concerns not only text, but graphics as well. 
 Content must be unique and relevant to the web-page’s subject. Content 
copying will inevitably result in website getting filtered and loss of 
positions. Correct use of keywords in texts, titles and Alt media 
content attributes guarantees high positions.
8. Internal links.
An irregularly distributed static weight 
obtained via visited links. Generally most of side web-sources refer to 
the home page. With SEO-expert’s help you can create a proper internal 
links structure to distribute the static weight between all web-pages. 
9. Web-pages loading speed
Fast loading speed doesn’t influence the 
position growth, but definitely improves the behavioral factors. High 
usability level attracts more users, improves CTR index, Google trust 
rank and lowers the bounce rate. To make it happen, experts optimize 
text/HTML code and media content ratio that slows the web-pages loading.
  
10. Mobile rendering.
A relatively new SEO-factor that Google 
takes into consideration during website ranking. Due to the fact that 
most users browse website through portable devices (smartphone, tablet),
 it would be a wise decision to make a website’s mobile version.
11. Bounce rate.
A percentage of visitors who usually view 
only one page of the website and then resume browsing. Websites with 
high bounce rate have several internal optimization problems: slow 
loading speed, non-optimized media content, complicated navigation, 
misuse of java-elements, etc.  
Bounce rate can’t be considered an 
SEO-factor analysis model due to the lots of cases of false bounce rate 
i.e. user obtaining necessary information (contact data, pricing, etc.) 
and leaves at once. 
Off-Page SEO factors
1. Link authority features.
CTR (click-through rate) and trust indexes
 are of a great importance for Google and heavily depend on the majority
 of other SEO-factors. The more users click the link, the higher 
website’s positions grow. Professional SEOs will instruct you how to 
improve website’s visibility and attract more visitors. 
2. Link building.
Backlinks number is one of the most 
important website promotion websites. Google takes into account both 
quality and quantity. Using backlinks incorrectly and misusing the 
method may result in vindictive damages issued by search engine. SEO 
company experts suggest using link building as productively as possible 
by placing links on the trustworthy websites in the following ratio:
- 50% — anchor
 - 40% — non-anchor
 - 10% — branded links
 
3. Social signals.
Communication with users via social 
networks helps increase website attendance and positions growth.  Social
 Media Marketing is specialized in brand promotion on popular websites. 
 SEOs recommend to create accounts and groups on Facebook, Twitter, 
Google+, LinkedIn and place social networks widgets on the website. As a
 rule SMM-managers are entrusted with networking, regularly making 
publications from the brand’s name, making updates, attracting 
subscribers and launching PR-campaigns. 
4. Geotargeting.
There is no point in promoting your 
website on the territory where your product and services are 
unavailable. Google is incredibly user-oriented, so its search results 
are adjusted depending on the country, region or city. Getting 
Registration in Google Maps and placing widgets on the website is 
obviously advantageous for local SEO.
SEO-campaigns
The SEO-campaign’s success is estimated 
via web-analysis.  Statistics reports help the webmaster to trace the 
positions change and adjust their strategy. Website visibility
 a.k.a the percentage of times the website is targeted in Google SERP 
can be improved by all of the abovementioned factors. The effectiveness 
of the promotion can be calculated by comparing current visibility 
percentage with the previous ones.
