You can publish in HI journals, cite your previous work in your own papers, send copies of your publication to notable researchers, list it on sites such as RG, etc.

Jevas - I take the measures that I always take. It's important to do the background checks if you wish your work to have the greatest chance of impact. I investigate the ranking databases i.e. ISI, Scimago according to the discipline that best fits my research topic. Depending on my previous experiences and my (or team) evaluation of the manuscript to be submitted, I rank the top 5 highest impact journals that I think I have a reasonable chance in. If I have not published with them before then I check the journal background i.e. scope, distribution, citation rates etc. Then I submit to the highest ranked first, on my list, and then keep going until it is accepted - following reviewer feedback and adjustment. Even with the lower journals on my list - there is still a good chance of reasonable impact overall.

I share my publications on researchgate and with my co-workers, friends wherever they are. I think this can also increase the impact of my publications.

Thanks for sharing your thoughts

You can increase your factor when you are publish in journal with high impact factor, and you have citation rate.
