SEO is a perfect combination of on-page and off-page. On-page Optimization is the most important factor before starting off-page. Enhancing the website and solving all technical issues will have an effective impact, if off-page is done in a relevant way.

I have observed that most of them still work with old methodologies in off-page. Drop all them out and start off the fresh one. Focus more on conversions, because getting your client conversions will only help you increase your ROI.

Here are factors related to Off-page that we all need to focus on:
1. Follow relevancy: Relevancy will help you gain trust and you will get your target audience.
2. Do not use Promotional Stuff . Write useful information to solve the problems of the users.
3. Create interactive content and social media posts.
4. Do not repeat the same activity if it does not show you results. Example: If you feel classified ads are not working then do not continue it. Instead find an alternative for it. It could be flyer ads.
5. Find opportunities with relevancy, do not waste an opportunity. Example: If you are creating a profile see to it that everything is filled up, do not leave it incomplete.
6. Quality of the context is important. Relevancy and quality are the two main concept of building backlinks.
7. You should be strong with you're searching techniques, that will gain you good results.

Few Off Page Techniques:

1. Guestography
2. Competitor based links
3. Forums
3. Question and answer
4. YouTube Optimization (Sharing Embedded URLs)
5. News Release (On high Quality sites)
6. Content Management
7. Viral Marketing

Note: Always use the best technique that suits your niche. Search and explore strategies that will gain you conversions.

There are lots of tasks you can follow for link building namely,

1. Social Bookmarking
2. Blog Submission
3. Article Submission
4. Directory Submission
5. VIdeo Sharing
6. Document Sharing

But remember to submit all these in only Web2.0 sites

There are many off page tasks which were working pretty well few years back like directory submission, article submission, social bookmarking but they are not very effective at the moment. In these days you only need high quality first tier backlinks from authorized websites and blogs and you should always use unique and original content for your link building work.

I am doing the following off off page works -
1. Classified Listing
2. Business Listing
3. Profile Creation
4. Article Posting
5. Blog Posting
6. Video Sharing
7. Forum Commenting
8. Blog Commenting

But, I must say that on page SEO work is as important as off page SEO to get top ranks.
